This dataset contains the Marine Optical Buoy (MOBY) ancillary (deployment) files. These are HTML pages which have auxiliary data associated with each data set in the deployment. The data file formats are in text (ASCII) and HTML. The images are in JPG and PNG formats; they are not compressed. The time period covered by the MOBY ancillary (deployment) dataset begins at 1997-07-29. The project is ongoing and continuous. More data is added as updates to the data record become available.

MOBY is an autonomous radiometric buoy stationed in the waters off Lanai, Hawaii. MOBY has been the primary in-water oceanic observatory for the vicarious calibration of U. S. satellite ocean color sensors since 1997. The MOBY project data set has been evaluated by NOAA, NASA, and NIST for its accuracy and precision numerous times since 1997. The MOBY measurements are calibrated with SI standards every per and post deployments to ensure the data sets continue to provide accurate and precise data. The satellite ocean color vicarious calibration community uses the data to validate the satellite measured radiance.

MOBY was designed to measure sunlight incidents both on and scattered out of the ocean. These measurements are provided in near real-time for the vicarious calibration procedures conducted by ocean color scientists. It is a NOAA-funded project that provides for the vicarious calibration of ocean color satellites such as SeaWiFS and MODIS. Currently, MOBY provides data to JPSS VIIRS and to non-NOAA agency partners, including Copernicus Sentinel 3A and 3B.

Processing Steps
  • The MOBY project data set has been evaluated by NOAA, NASA, and NIST for its accuracy and precision numerous times since 1997. The MOBY measurements are calibrated with SI standards every per and post deployments to ensure the data set's continued accuracy and precision. Please contact NOAA/NESDIS/STAR/SOCD CoastWatch for further information.
    Rationale: The purpose is to ensure the accuracy and precision of the data from the buoy.
Processing EnvironmentThe radiance standards for MOBY are two integrating spheres with calibrations based on standards traceable to the National Institute of Standards and Technology (NIST). For irradiance, the MOBY project uses standard lamps that are routinely recalibrated at NIST. Wavelength calibrations are conducted with a series of emission lines observed from a set of low pressure lamps. Each MOBY instrument views these standards before and after its deployment to provide system responses (calibration coefficients). During each deployment, the stability of the MOBY spectrographs and internal optics are monitored using three internal reference sources. In addition, the collection optics for the instrument are cleaned and checked on a monthly basis while the buoy is deployed. As part of collaboration with NIST, annual radiometric comparisons are made at the MOBY calibration facility. NIST personnel use transfer radiometers and integrating spheres to validate (verify) the accuracy of the MOBY calibration sources.
