A separate metadata file with a .xml file extension was also delivered to NSIDC with the HDF-EOS file; it contains the same information as the core metadata. Three levels of QA are conducted with the AMSR Level 2 products: automatic, operational, and science QA. If a product does not fail QA, it is ready to be used for higher-level processing, browse generation, active science QA, archive, and distribution. If a granule fails QA, SIPS does not send the granule to NSIDC until it is reprocessed. Only a QA file is produced when there is no L2A brightness temperature data that qualifies for retrieval (Conway 2002).These data are freely, openly, and fully accessible, provided that you are logged into your NASA Earthdata profile (https://urs.earthdata.nasa.gov/).These data are freely, openly, and fully available to use without restrictions, provided that you cite the data according to the recommended citation at https://nsidc.org/about/use_copyright.html.

For more information regarding related publications, see the Research Using AMSR Data Web page.The AMSR Level-2A product (AA_L2A) contains brightness temperatures at 6.9 GHz, 10.65 GHz, 18.7 GHz, 23.8 GHz, 36.5 GHz, 89.0 GHz, 50.3 GHz, and 52.8GHz. Data are resampled to be spatially consistent except for the 50.3GHz and 52.8GHz data, and therefore are available at a variety of resolutions that correspond to the footprint sizes of the observations such as 56 km, 38 km, 24 km, 21 km, 12 km, and 5.4 km, respectively.VIEW RELATED INFORMATIONhttps://doi.org/10.5067/ADEOS-II/AMSR/AA_L2A.001DocumentationGET DATAhttps://n5eil01u.ecs.nsidc.org/AMSA/AA_L2A.001/HTTPSGET DATAhttps://nsidc.org/data/data-access-tool/AA_L2A/versions/1/Data Access ToolPROJECT HOME PAGEhttp://nsidc.org/data/amsre/index.htmlAqua/AMSR-E DataPROJECT HOME PAGEhttp://nsidc.org/data/amsr/index.htmlAMSR/ADEOS-II DataUSA/NASACEOS IDN DIFVERSION 9.92009-04-152023-11-29NSIDCVersion SummaryInitial data product release.NSIDCMinor VersionNSIDCCurrent Version1NSIDCLevel of ServiceStandardNSIDCFull Dataset CitationJapan Aerospace Exploration Agency (JAXA). 2009. <i>AMSR/ADEOS-II L2A Global Swath Spatially-Resampled Brightness Temperatures.</i> [indicate subset used].
