DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperatures, Version 4
Data set id:
There is a more recent version of these data.
- Updated version to reflect the beginning of the F17 data record
- The source for this data set, RSS, changed from their version from V4 to V7
- RSS V7 cross-calibrates between all SSM/I and SSMIS sensors as well as AMSR-E and WindSat, providing interconsistency of brightness temperatures from the sensors
This data set provides daily gridded brightness temperatures derived from passive microwave sensors and distributed in a polar stereographic projection. Orbital data from nine channels and for each 24-hour period are mapped to respective grid cells using a simple sum and average method (drop-in-the-bucket method).
