Description

As of 31 August 2022, this data set is retired and no longer available for download. We recommend using MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR, Version 1 data set as an alternative. This data set provides daily, near-real-time Special Sensor Microwave Imager/Sounder (SSMIS) brightness temperatures in the Equal-Area Scalable Earth-Grid (EASE-Grid). The data set consists of gridded data in two projections: Northern Hemisphere and Southern Hemisphere. The data lag by one day and provide 365 days of near-real-time data. The spatial resolution is 25 km for all channels. Data are contained in flat binary files.

Version Description

For this Version 2 data set, NSIDC has switched its SSMIS processing stream from the DMSP-F17 satellite to SSMIS data from the DMSP-F18 satellite.
