The geophysical parameters include daily air surface temperature, fractional open water cover estimates, vegetation optical depth, surface volumetric soil moisture, and atmosphere total column precipitable water vapor. The global retrievals were derived over land for non-precipitating, non-snow, and non-ice covered conditions.</Abstract></Summary><Related_URL><URL_Content_Type><Type>VIEW RELATED INFORMATION</Type></URL_Content_Type><URL>https://doi.org/10.5067/RF8WPYOPJKL2</URL><Description>User's Guide</Description></Related_URL><Metadata_Name>CEOS IDN DIF</Metadata_Name><Metadata_Version>VERSION 9.9</Metadata_Version><DIF_Creation_Date>2017-10-25</DIF_Creation_Date><Last_DIF_Revision_Date>2026-05-21</Last_DIF_Revision_Date><Extended_Metadata><Metadata><Group>NSIDC</Group><Name>Version Summary</Name><Value>For Version 2, data were processed for the entire AMSR-E operational record (19 June 2002 to 4 October 2011) and part of the AMSR2 record (24 July 2012 to 30 June 2017), with planned updates and LPDR continuity enabled from continuing AMSR2 operations.
