Description

The Near-Real-Time DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperature product provides near-real-time polar stereographic gridded daily brightness temperatures for both the Northern and Southern Hemispheres.

As of 18 June 2026, this data set is retired and no longer available for download. Forward processing for this product ceased in January 2026. We recommend using the research quality DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperatures (https://doi.org/10.5067/MXJL42WSXTS1) data set as an alternative.

Version Description

This version update reflects the conversion of the data set from binary to NetCDF.
