AVHRR measurements of atmospheric aerosols over oceans. Final report
Technical Report
·
OSTI ID:5138852
A large set of AVHRR and ground-truth data was obtained at ten sites around the globe to investigate the possible global variability of the radiance-aerosol content relationship observed previously with Landsat data. The aerosol content was inferred from the AVHRR Channel 1 radiance using an algorithm based on previous Landsat measurements at San Diego. The data for four sites have been analyzed, and show excellent agreement between the aerosol content measured by the AVHRR and by sunphotometers at San Diego, Sable Island and San Juan, but at Barbados, the AVHRR appears to overestimate the aerosol content. The reason for the different relationship at the Barbados site has not been definitely established, but is most likely related to problems in interpreting the sunphotometer data rather than to a real overestimation by the AVHRR.
