NSIDC would like to report an error currently in two near-real-time data products: the Near-Real-Time DMSP SSM/I Daily Polar Gridded Brightness Temperatures and the Near-Real-Time DMSP SSM/I-SSMIS Pathfinder Daily EASE-Grid Brightness Temperatures. A calibration problem in the F17 37H GHz channel is causing a bias of 3 to 4 Kelvin lower than should be reported for the 37H GHz channel.
