It is highly recommended that users access the current version. Users should only use this version for special cases, such as reproducing studies that used this version.* This NOAA Climate Data Record (CDR) of Aerosol Optical Thickness (AOT) is derived from data taken over global oceans from the PATMOS-x AVHRR level-2b channel 1 (0.63 micron) orbital clear-sky radiance. The retrieval is performed for selected spatial (8-km) and temporal (1 time per day) resolution in cloud free condition during daytime over global oceans. The AVHRR AOT CDR version 2 extends from 1981 to 2009 and includes both daily and monthly data in an equal angle grid (0.1x0.1 degree). Version 2 has improved cloud screening and data processing from version 1. Due to the relatively large uncertainties associated with surface reflectance over water glint area and land surface as well as limited AVHRR retrieval channels, the current algorithm only performs retrieval over non-glint water surface (specifically at the anti-solar side of the orbit and viewing angle is larger than 40 degree away from the specular ray). This dataset provides a high quality Climate Data Record (CDR) of aerosol optical thickness (AOT). As a high quality climate data record, this dataset can be used for climate model evaluation as well as air pollution and climate assessment. completed superseded historicalArchive NOAA Climate Data Record Program Office DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce +1 (828) 271-4800 151 Patton Avenue Asheville NC 28801 USA avhrr_aot_contacts@noaa.gov pointOfContact notPlanned https://www.ncei.noaa.gov/pub/data/metadata/images/C00858.PNG AVHRR AOT monthly file example PNG Earth Science > Atmosphere > Aerosols > Aerosol Optical Depth/Thickness theme Global Change Master Directory (GCMD) Science Keywords 2018 revision Version 8.6 Global Change Data Center, Science and Exploration Directorate, Goddard Space Flight Center (GSFC) National Aeronautics and Space Administration (NASA) https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-gcmd-keywords HTTPS Web Browser Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.
