      <gmd:abstract>
        <gco:CharacterString>The primary products are global one degree maps of aerosol optical thickness based on one week's worth of data. Currently they are created from AVHRR channel 1 optical thickness retrievals from AVHRR global area coverage (GAC) data. Optical thickness, or optical depth,is a dimensionless quantity that indicates the amount of depletion that a beam of radiation undergoes as it passes through a layer of the atmosphere. Optical depth is a function of the density, composition, temperature, pressure, and volume of the layer. Aerosols are defined as suspensions of liquid droplets or solid particles in the atmosphere, including dust, smoke, sand, volcanic ash, sea spray and smog.</gco:CharacterString>
      </gmd:abstract>
      <gmd:purpose>
        <gco:CharacterString>Originally developed for the purpose of correcting sea surface temperatures for aerosol attenuation. Aerosols in the atmosphere that are not detected by nominal cloud screening will cause the top-of-the-atmosphere temperatures sensed by the AVHRR instrument to be too cold. Thus, the aerosol optical thickness product was developed to try to estimate the amount of aerosol in the observation path and enable a temperature correction based on this estimate.</gco:CharacterString>

                        <gco:CharacterString>Aerosol products are produced on a weekly basis, using a revised (Phase 2) single channel algorithm for aerosol optical thickness retrieval over oceans from radiances in Channel 1. This algorithm scales the upward satellite radiances in cloud-free conditions to aerosol optical thickness using an updated radiative transfer model of the ocean and atmosphere. The primary products are a global one degree map of Aerosol Optical Thickness based on a composite of one week's worth of data and the monthly mean product.</gco:CharacterString>

                <gco:CharacterString>Instrument Type: imager (scanning monochromator) and sounder (a cloud cover radiometer), Operational Mode: Discrete mode, sweep mode or diffuser plate mode., Collection Type: nonspatial scanning, Other Information: The SBUV/2 is a nadir pointing nonspatial scanning            instrument sensitive to radiation in the 160 nm to 400 nm ultraviolet spectrum. The SBUV/2 instruments on the TIROS-N satellites are designed to measure the total ozone in a vertical column beneath the satellite and its distribution with height in the atmosphere. The SBUV/2 contains a            scanning double monochromator and a cloud cover radiometer (CCR) designed to measure ultraviolet (UV) spectral intensities. In its primary mode of operation, the monochromator measures solar radiation backscatter by the atmosphere in 12 discrete wavelength bands in the near-UV, ranging            from 252.0 to 339.8 nm, each with a bandpass of 1.1 nm. The total-ozone algorithm uses the four longest wavelength bands (312.5, 317.5, 331.1, and 339.8 nm), whereas the profiling algorithm uses the shorter wavelengths. The cloud cover radiometer operates at 379 nm (i.e. outside the            ozone absorption band) with a 3.0-nm bandpass and was designed to measure the reflectivity of the surface in the instantaneous field of view (IFOV). The SBUV/2 also makes periodic measurements of the solar flux by deploying a diffuser plate into the field of view (FOV) to reflect            sunlight into the instrument. The monochromator and the cloud cover radiometer are mounted so that they look in the nadir direction with coincident nominal FOV's of 11.3 by 11.3 degrees. As the satellite moves in a Sun-synchronous orbit, the FOV traces 160-km wide paths on the ground.            The earth rotates approximately 26 degrees during each orbit. The satellite footprint moves at a speed of about 6 km/sec. In discrete mode a set of 12 measurements, 1 for each discrete wavelength band, is taken every 32 seconds. The order of measurements is 252.0 to 339.8 and the            integration time is 1.25 seconds per measurement. For each monochromator measurement there is a cloud cover radiometer measurement.</gco:CharacterString>

                <gco:CharacterString>The EPS accurately measures the number of particles over a broad energy range, including protons, electrons, and alpha particles. The magnetometer sensors can operate independently and simultaneously to measure the magnitude and direction of the Earth's geomagnetic field, detect variations in the magnetic field near the spacecraft, provide alerts of solar wind shocks or sudden impulses that impact the magnetosphere, and assess the level of geomagnetic activity. The second magnetometer sensor serves as a backup. The XRS is an x-ray telescope that observes and measures solar x-ray emissions in two ranges: one from 0.05 to 0.3 nanometers (nm) and the second from 0.1 to 0.8 nm. In real-time, it measures the intensity and duration of solar flares</gco:CharacterString>

                <gco:CharacterString>Instrument Type: sounder, Operational Mode: cross-track, Collection Type: continuous scan, Other Information: The HIRS/4 instrument provides multispectral data from one visible channel (0.69 m), seven shortwave channels (3.7 to 4.6 m) and twelve longwave channels (6.7 to            15 m) using a single telescope and a rotating filter wheel containing twenty individual spectral filters. An elliptical scan mirror provides cross-track scanning of 56 steps in increments of 1.8 degrees. The mirror steps rapidly (&lt;35 msec), then holds at each position while the            optical radiation , passing through the 20 spectral filters, is sampled. This action takes place each 0.1 second. The instantaneous field of view for each channel is approximately 0.7 degrees which, from a spacecraft altitude of 833 km, encompasses a circular area of 10 km at nadir on            the earth.</gco:CharacterString>

                <gco:CharacterString>Instrument Type: imager (scanning monochromator) and sounder (a cloud cover radiometer), Operational Mode: Discrete mode, sweep mode or diffuser plate mode., Collection Type: nonspatial scanning, Other Information: The SBUV/2 is a nadir pointing nonspatial scanning            instrument sensitive to radiation in the 160 nm to 400 nm ultraviolet spectrum. The SBUV/2 instruments on the TIROS-N satellites are designed to measure the total ozone in a vertical column beneath the satellite and its distribution with height in the atmosphere. The SBUV/2 contains a            scanning double monochromator and a cloud cover radiometer (CCR) designed to measure ultraviolet (UV) spectral intensities. In its primary mode of operation, the monochromator measures solar radiation backscatter by the atmosphere in 12 discrete wavelength bands in the near-UV, ranging            from 252.0 to 339.8 nm, each with a bandpass of 1.1 nm. The total-ozone algorithm uses the four longest wavelength bands (312.5, 317.5, 331.1, and 339.8 nm), whereas the profiling algorithm uses the shorter wavelengths. The cloud cover radiometer operates at 379 nm (i.e. outside the            ozone absorption band) with a 3.0-nm bandpass and was designed to measure the reflectivity of the surface in the instantaneous field of view (IFOV). The SBUV/2 also makes periodic measurements of the solar flux by deploying a diffuser plate into the field of view (FOV) to reflect            sunlight into the instrument. The monochromator and the cloud cover radiometer are mounted so that they look in the nadir direction with coincident nominal FOV's of 11.3 by 11.3 degrees. As the satellite moves in a Sun-synchronous orbit, the FOV traces 160-km wide paths on the ground.            The earth rotates approximately 26 degrees during each orbit. The satellite footprint moves at a speed of about 6 km/sec. In discrete mode a set of 12 measurements, 1 for each discrete wavelength band, is taken every 32 seconds. The order of measurements is 252.0 to 339.8 and the            integration time is 1.25 seconds per measurement. For each monochromator measurement there is a cloud cover radiometer measurement.</gco:CharacterString>

                <gco:CharacterString>The EPS accurately measures the number of particles over a broad energy range, including protons, electrons, and alpha particles. The magnetometer sensors can operate independently and simultaneously to measure the magnitude and direction of the Earth's geomagnetic field, detect variations in the magnetic field near the spacecraft, provide alerts of solar wind shocks or sudden impulses that impact the magnetosphere, and assess the level of geomagnetic activity. The second magnetometer sensor serves as a backup. The XRS is an x-ray telescope that observes and measures solar x-ray emissions in two ranges: one from 0.05 to 0.3 nanometers (nm) and the second from 0.1 to 0.8 nm. In real-time, it measures the intensity and duration of solar flares</gco:CharacterString>

                <gco:CharacterString>Instrument Type: sounder, Operational Mode: cross-track, Collection Type: continuous scan, Other Information: The HIRS/4 instrument provides multispectral data from one visible channel (0.69 m), seven shortwave channels (3.7 to 4.6 m) and twelve longwave channels (6.7 to            15 m) using a single telescope and a rotating filter wheel containing twenty individual spectral filters. An elliptical scan mirror provides cross-track scanning of 56 steps in increments of 1.8 degrees. The mirror steps rapidly (&lt;35 msec), then holds at each position while the            optical radiation , passing through the 20 spectral filters, is sampled. This action takes place each 0.1 second. The instantaneous field of view for each channel is approximately 0.7 degrees which, from a spacecraft altitude of 833 km, encompasses a circular area of 10 km at nadir on            the earth.</gco:CharacterString>

                <gco:CharacterString>Instrument Type: imager (scanning monochromator) and sounder (a cloud cover radiometer), Operational Mode: Discrete mode, sweep mode or diffuser plate mode., Collection Type: nonspatial scanning, Other Information: The SBUV/2 is a nadir pointing nonspatial scanning            instrument sensitive to radiation in the 160 nm to 400 nm ultraviolet spectrum. The SBUV/2 instruments on the TIROS-N satellites are designed to measure the total ozone in a vertical column beneath the satellite and its distribution with height in the atmosphere. The SBUV/2 contains a            scanning double monochromator and a cloud cover radiometer (CCR) designed to measure ultraviolet (UV) spectral intensities. In its primary mode of operation, the monochromator measures solar radiation backscatter by the atmosphere in 12 discrete wavelength bands in the near-UV, ranging            from 252.0 to 339.8 nm, each with a bandpass of 1.1 nm. The total-ozone algorithm uses the four longest wavelength bands (312.5, 317.5, 331.1, and 339.8 nm), whereas the profiling algorithm uses the shorter wavelengths. The cloud cover radiometer operates at 379 nm (i.e. outside the            ozone absorption band) with a 3.0-nm bandpass and was designed to measure the reflectivity of the surface in the instantaneous field of view (IFOV). The SBUV/2 also makes periodic measurements of the solar flux by deploying a diffuser plate into the field of view (FOV) to reflect            sunlight into the instrument. The monochromator and the cloud cover radiometer are mounted so that they look in the nadir direction with coincident nominal FOV's of 11.3 by 11.3 degrees. As the satellite moves in a Sun-synchronous orbit, the FOV traces 160-km wide paths on the ground.            The earth rotates approximately 26 degrees during each orbit. The satellite footprint moves at a speed of about 6 km/sec. In discrete mode a set of 12 measurements, 1 for each discrete wavelength band, is taken every 32 seconds. The order of measurements is 252.0 to 339.8 and the            integration time is 1.25 seconds per measurement. For each monochromator measurement there is a cloud cover radiometer measurement.</gco:CharacterString>

                <gco:CharacterString>The EPS accurately measures the number of particles over a broad energy range, including protons, electrons, and alpha particles. The magnetometer sensors can operate independently and simultaneously to measure the magnitude and direction of the Earth's geomagnetic field, detect variations in the magnetic field near the spacecraft, provide alerts of solar wind shocks or sudden impulses that impact the magnetosphere, and assess the level of geomagnetic activity. The second magnetometer sensor serves as a backup. The XRS is an x-ray telescope that observes and measures solar x-ray emissions in two ranges: one from 0.05 to 0.3 nanometers (nm) and the second from 0.1 to 0.8 nm. In real-time, it measures the intensity and duration of solar flares</gco:CharacterString>

Operational Dates: April 11, 1995 to October 07, 2002. Operational Status: decommissioned on May 23, 2007. NOAA-14 was placed in a near circular, (470nm) polar orbit. It is the sixth operational satellite in the Advanced TIROS-N series            and replaced NOAA-11. The spacecraft was rectangular shaped and powered by a 191" by 94"solar array. The satellite was Earth oriented, three-axis stabilized and weighed approximately 2200 pounds.</gco:CharacterString>

                <gco:CharacterString>Instrument Type: sounder, Operational Mode: crosstrack, Collection Type: step-scan, Other Information: The SSU consists of a single primary telescope with a 10 degree IFOV which is step-scanned perpendicular to the satellite subpoint track. Each scan line is composed of            eight individual 4.0 second steps and requires a total of 32 seconds, including time for the mirror retrace. The 10 degree IFOV gives a resolution of 147 km at the satellite subpoint and the stepping produces an underlap between adjacent scan lines of approximately 62 km at nadir. A            calibration sequence is initiated every 256 seconds (8 scans) during which the radiometer is in turn, stepped to a position to view unobstructed space and an internal blackbody at a known temperature.</gco:CharacterString>

                <gco:CharacterString>Instrument Type: imager (scanning monochromator) and sounder (a cloud cover radiometer), Operational Mode: Discrete mode, sweep mode or diffuser plate mode., Collection Type: nonspatial scanning, Other Information: The SBUV/2 is a nadir pointing nonspatial scanning            instrument sensitive to radiation in the 160 nm to 400 nm ultraviolet spectrum. The SBUV/2 instruments on the TIROS-N satellites are designed to measure the total ozone in a vertical column beneath the satellite and its distribution with height in the atmosphere. The SBUV/2 contains a            scanning double monochromator and a cloud cover radiometer (CCR) designed to measure ultraviolet (UV) spectral intensities. In its primary mode of operation, the monochromator measures solar radiation backscatter by the atmosphere in 12 discrete wavelength bands in the near-UV, ranging            from 252.0 to 339.8 nm, each with a bandpass of 1.1 nm. The total-ozone algorithm uses the four longest wavelength bands (312.5, 317.5, 331.1, and 339.8 nm), whereas the profiling algorithm uses the shorter wavelengths. The cloud cover radiometer operates at 379 nm (i.e. outside the            ozone absorption band) with a 3.0-nm bandpass and was designed to measure the reflectivity of the surface in the instantaneous field of view (IFOV). The SBUV/2 also makes periodic measurements of the solar flux by deploying a diffuser plate into the field of view (FOV) to reflect            sunlight into the instrument. The monochromator and the cloud cover radiometer are mounted so that they look in the nadir direction with coincident nominal FOV's of 11.3 by 11.3 degrees. As the satellite moves in a Sun-synchronous orbit, the FOV traces 160-km wide paths on the ground.            The earth rotates approximately 26 degrees during each orbit. The satellite footprint moves at a speed of about 6 km/sec. In discrete mode a set of 12 measurements, 1 for each discrete wavelength band, is taken every 32 seconds. The order of measurements is 252.0 to 339.8 and the            integration time is 1.25 seconds per measurement. For each monochromator measurement there is a cloud cover radiometer measurement.</gco:CharacterString>

                <gco:CharacterString>Instrument Type: imager (scanning monochromator) and sounder (a cloud cover radiometer), Operational Mode: Discrete mode, sweep mode or diffuser plate mode., Collection Type: nonspatial scanning, Other Information: The SBUV/2 is a nadir pointing nonspatial scanning            instrument sensitive to radiation in the 160 nm to 400 nm ultraviolet spectrum. The SBUV/2 instruments on the TIROS-N satellites are designed to measure the total ozone in a vertical column beneath the satellite and its distribution with height in the atmosphere. The SBUV/2 contains a            scanning double monochromator and a cloud cover radiometer (CCR) designed to measure ultraviolet (UV) spectral intensities. In its primary mode of operation, the monochromator measures solar radiation backscatter by the atmosphere in 12 discrete wavelength bands in the near-UV, ranging            from 252.0 to 339.8 nm, each with a bandpass of 1.1 nm. The total-ozone algorithm uses the four longest wavelength bands (312.5, 317.5, 331.1, and 339.8 nm), whereas the profiling algorithm uses the shorter wavelengths. The cloud cover radiometer operates at 379 nm (i.e. outside the            ozone absorption band) with a 3.0-nm bandpass and was designed to measure the reflectivity of the surface in the instantaneous field of view (IFOV). The SBUV/2 also makes periodic measurements of the solar flux by deploying a diffuser plate into the field of view (FOV) to reflect            sunlight into the instrument. The monochromator and the cloud cover radiometer are mounted so that they look in the nadir direction with coincident nominal FOV's of 11.3 by 11.3 degrees. As the satellite moves in a Sun-synchronous orbit, the FOV traces 160-km wide paths on the ground.            The earth rotates approximately 26 degrees during each orbit. The satellite footprint moves at a speed of about 6 km/sec. In discrete mode a set of 12 measurements, 1 for each discrete wavelength band, is taken every 32 seconds. The order of measurements is 252.0 to 339.8 and the            integration time is 1.25 seconds per measurement. For each monochromator measurement there is a cloud cover radiometer measurement.</gco:CharacterString>

                <gco:CharacterString>The EPS accurately measures the number of particles over a broad energy range, including protons, electrons, and alpha particles. The magnetometer sensors can operate independently and simultaneously to measure the magnitude and direction of the Earth's geomagnetic field, detect variations in the magnetic field near the spacecraft, provide alerts of solar wind shocks or sudden impulses that impact the magnetosphere, and assess the level of geomagnetic activity. The second magnetometer sensor serves as a backup. The XRS is an x-ray telescope that observes and measures solar x-ray emissions in two ranges: one from 0.05 to 0.3 nanometers (nm) and the second from 0.1 to 0.8 nm. In real-time, it measures the intensity and duration of solar flares</gco:CharacterString>

            <gco:CharacterString>NOAA-15 (K) - Launch: May 13, 1998. Instruments: AVHRR/3, TOVS (HIRS/3, AMSU-A1, AMSU-A2, AMSU-B), SEM/2, SARSAT (SARR, SARP/2), Argos/DCS/2 Operational dates: December 15, 1998 to Present.            Operational Status: AM Secondary. NOAA-15 was placed in a near circular, (450nm) polar orbit. It is the seventh operational satellite in the Advanced TIROS-N series. It is the first in the series to support            dedicated microwave instruments for the generation of temperature, moisture and surface hydrological products in cloudy regions where visible and infrared instruments have reduced capabilities. The spacecraft            was rectangular shaped (4.2m long by 1.88m high) and powered by a 6.14m by 2.73m solar array. The satellite was Earth oriented, three-axis stabilized and weighed approximately 2200 kg.</gco:CharacterString>

                <gco:CharacterString>The EPS accurately measures the number of particles over a broad energy range, including protons, electrons, and alpha particles. The magnetometer sensors can operate independently and simultaneously to measure the magnitude and direction of the Earth's geomagnetic field, detect variations in the magnetic field near the spacecraft, provide alerts of solar wind shocks or sudden impulses that impact the magnetosphere, and assess the level of geomagnetic activity. The second magnetometer sensor serves as a backup. The XRS is an x-ray telescope that observes and measures solar x-ray emissions in two ranges: one from 0.05 to 0.3 nanometers (nm) and the second from 0.1 to 0.8 nm. In real-time, it measures the intensity and duration of solar flares</gco:CharacterString>
