The AMSR-E/AMSR2 Unified L2B Global Swath Ocean Products, Version 1, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), is currently being updated to include the AMSR-E portion of the dataset from 2002 to 2011, as well as select AMSR2 data from 2017 to 2021. These files are being delivered to us in batches and will be made available as we receive them.
This AMSR Unified global ocean dataset reports integrated water vapor and cloud liquid water content in the atmospheric column, as well as 10-meter sea surface wind speeds. The data is derived from AMSR-E and AMSR2 brightness temperature observations that have been resampled by the Japan Aerospace Exploration Agency to facilitate an intercalibrated (i.e. "unified") AMSR-E/AMSR2 data record.
