NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC)

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has updated the Near-Real-Time DMSP SSMIS Daily Polar Gridded Brightness Temperatures data set so that it now solely provides data from the DMSP-F18 SSMIS sensor beginning with 01 April 2016 due to the compromised data integrity of the DMSP-F17 SSMIS vertically polarized 37 GHz channel (37V). Data before 01 April 2016 are still from the F17 SSMIS.

Due to the compromised data integrity with the DMSP F17 vertically polarized 37 GHz channel (37V) of the Special Sensor Microwave Imager and Sounder (SSMIS), which is a primary channel used for sea ice development, NSIDC is halting production of the Near-Real-Time DMSP SSMIS Daily Polar Gridded Sea Ice Concentrations F17 data and switching over to the F18 satellite, starting with 1 April 2016 data. However, NSIDC is still working on the calibration of the F18 data so temporarily the F18 data will be uncalibrated and using F17 tie points.

Due to the compromised data integrity with the Defense Meteorological Satellite Program (DMSP) F-17 vertically polarized 37 GHz channel (37V) of the Special Sensor Microwave Imager and Sounder (SSMIS), NSIDC will be distributing data from both the F17 and F18 satellites, starting with 1 April 2016 data. Using data from the 37V channel from the F17 satellite is not recommended. Instead, you should use data from the F18 satellite’s 37V channel.

Four Version 6 MODIS snow cover data sets are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC):

Version 3 of the EASE-Grid Sea Ice Age data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The input ice motion data used for this data set is now derived from NSIDC-0116 Version 3 data, and the data were updated through 31 May 2015.
