As this product is intended to provide a follow-on data set for Near-Real-Time DMSP SSMIS Daily Polar Gridded Brightness Temperatures (NSIDC-0080), it uses TB fields gridded to match TBs gridded from SSMIS sensors on the same 25km polar stereo grids.</Abstract></Summary><Related_URL><URL_Content_Type><Type>VIEW RELATED INFORMATION</Type></URL_Content_Type><URL>https://nsidc.org/sites/default/files/documents/user-guide/nsidc-0802-v002-userguide_0.pdf</URL><Description>AMSR2 Daily Polar Gridded Brightness Temperatures, Version 2 User Guide</Description></Related_URL><Related_URL><URL_Content_Type><Type>GET DATA</Type></URL_Content_Type><URL>https://daacdata.apps.nsidc.org/pub/DATASETS/nsidc0802_daily_a2_tb_v2/</URL><Description>HTTPS</Description></Related_URL><Metadata_Name>CEOS IDN DIF</Metadata_Name><Metadata_Version>VERSION 9.9</Metadata_Version><DIF_Creation_Date>2025-08-19</DIF_Creation_Date><Last_DIF_Revision_Date>2026-01-26</Last_DIF_Revision_Date><Extended_Metadata><Metadata><Group>NSIDC</Group><Name>Version Summary</Name><Value>Version update reflects the conversion of the data set from binary to NetCDF and adds the 37H channel.</Value></Metadata><Metadata><Group>NSIDC</Group><Name>Minor Version</Name><Value/></Metadata><Metadata><Group>NSIDC</Group><Name>Current Version</Name><Value>1</Value></Metadata><Metadata><Group>NSIDC</Group><Name>Spatial Reference Systems</Name><Value><Spatial_Reference_System><SRID>EPSG:3411</SRID><Description>NSIDC Sea Ice Polar Stereographic North</Description></Spatial_Reference_System><Spatial_Reference_System><SRID>EPSG:3412</SRID><Description>NSIDC Sea Ice Polar Stereographic South</Description></Spatial_Reference_System></Value></Metadata><Metadata><Group>NSIDC</Group><Name>Level of Service</Name><Value><Level>Comprehensive</Level></Value></Metadata><Metadata><Group>NSIDC</Group><Name>Full Dataset Citation</Name><Value>Stewart, J.
