NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Aerosol Optical Depth (AOD)
ABI-L2-AOD
Example of Aerosol Optical Depth product retrieved over water from Terra/MODIS data during the Eyjafjallajökull, Iceland Volcano event, 19 April 2010 12:50 UTC.
The GOES-R Advanced Baseline Imager (ABI) Aerosol Optical Depth product contains an image with pixel values identifying a measure of the extinction due to atmospheric aerosols at a wavelength of 550 nm over land and ocean. The product includes data quality information that provides an assessment of the quality of the algorithm retrievals for on-earth pixels. The aerosol optical depth value is a dimensionless quantity. The Aerosol Optical Depth product image is produced on the ABI fixed grid at 2 km resolution for Full Disk and CONUS coverage regions from GOES East and West. Product data is produced under the following conditions: Clear sky; snow-free; Geolocated source data to local zenith angles of 90 degrees, to solar zenith angles of 90 degrees, and sunglint angles greater than 40 degrees when over the ocean.

Purpose | The Aerosol Optical Depth (AOD) product will utilize several spectral wavelengths of the ABI (Advanced Baseline Imager) to measure the reflectance properties of cloud-free pixels at the top of the atmosphere (TOA). These reflectance properties at the TOA are then fed into aerosol models to compute the surface reflectance and aerosol properties at the surface. The information provided by the AOD algorithm will aid meteorologists and others in making critical air quality, visibility, and aviation forecasts. In addition, AOD product will provide valuable data to be included in climate models and help climate scientists monitor and predict climate change. |
