DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperatures, Version 4
Data set id:
NSIDC-0001
DOI: 10.5067/AN9AI8EO7PX0
There is a more recent version of these data.
Version Summary

  • 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

Overview

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).
