AMSR-E/Aqua L2B Global Swath Ocean Products derived from Wentz Algorithm

View Catalog Page

Entry ID

AE_Ocean

Summary

The Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) instrument on the NASA Earth Observing System (EOS) Aqua satellite provides global passive microwave measurements of terrestrial, oceanic, and atmospheric variables for the investigation of water and energy cycles. Measurements of ocean variables improve our understanding of a wide variety of hydrological and radiative processes, including air-sea and air-ice interactions.

The Level-2B ocean swath product (AE_Ocean) contains Sea Surface Temperature (SST) at 56 km and 38 km resolution, near-surface wind speed at 38 km and 21 km resolution, columnar water vapor at 21 km resolution, columnar cloud liquid water at 12 km resolution, and quality flags. All variables were measured over oceans and are generated from the Wentz algorithm.

The Level-3 daily product (AE_DyOcn), weekly product (AE_WkOcn), and monthly product (AE_MoOcn) include SST, near-surface wind speed, columnar water vapor, and columnar cloud liquid water over oceans in a 0.25 degree by 0.25 degree grid, generated from AE_Ocean. Data are stored in Hierarchical Data Format - Earth Observing System (HDF-EOS) format, and are available from 19 June 2002 to 3 October 2011 via FTP.

Quality

Each HDF-EOS file contains core metadata with QA metadata flags that are set by the Science Investigator-led Processing System (SIPS) at the Global Hydrology and Climate Center (GHCC) prior to delivery to NSIDC. A separate metadata file (.xml file extension) is also delivered to NSIDC with the HDF-EOS file; it contains the same information as the core metadata. Three levels of quality assessment (QA) are conducted with the AMSR-E Level - 2 and -3 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. Level-3 products that fail QA are never delivered to NSIDC (Conway 2002).

The Level-2B ocean files contain three data elements related to quality assurance: the Scan_quality_flag, the Ocean_summary_quality_flag, and the Ocean_products_quality_flag.
