Data Release: Consistent Long-Term Aerosol Data Records over Land and Ocean from SeaWIFS

 

The Goddard Earth Sciences Data and Information Services Center (GES DISC) is pleased to announce the release of data from the Consistent Long-Term Aerosol Data Records over Land and Ocean from SeaWIFS project as part of the NASA Making Earth Science Data Records for Use in Research Environments (MEaSUREs) program (http://disc.sci.gsfc.nasa.gov/measures).
 
Long-term climate data records of aerosols are critically needed to form a consensus among the science community regarding the impact of aerosols on the global radiative budget. Towards this goal, this new data set was created using radiances from the long-running and well-calibrated SeaWiFS mission, in conjunction with a new ocean retrieval algorithm and an extended Deep Blue retrieval algorithm over land, covering both bright desert as well as vegetated surfaces. It consists of daily swath (Level 2) and gridded (Level 3) products, including aerosol optical thickness and Ångström exponent, with coverage over both land and ocean from 1997 through 2010. The Level 3 products are available at both 0.5° and 1.0° grid resolutions. The Principal Investigator for this project is Christina Hsu at NASA Goddard Space Flight Center.
 
The data is available now online and can be downloaded from the project website or directly via anonymous FTP:
 
The data has also been included in the GES DISC search tool, Mirador:
 
Finally, data descriptions are available via the Global Change Master Directory:
 
Questions on these data holdings can be sent to the GES DISC at help-disc@listserv.gsfc.nasa.gov. Technical questions regarding data production or the retrieval algorithms should be directed to Corey Bettenhausen at corey.bettenhausen@nasa.gov.
