The SMAP_L1B_TB_01966_A_20150614T231537_R13080_001.h5 file was removed from the SMAP L1B Radiometer Half-Orbit Time-Ordered Brightness Temperatures Data Set because of a problem with the Antenna Azimuth file used to process this half-orbit. The SMAP Science Data System (SDS) is working to correct the Antenna Azimuth file and regenerate the half-orbits. Once we receive the new file, we will let you know. If you have any questions, please contact our User Services Office via e-mail: nsidc@nsidc.org.

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.
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.
The Sea Ice Index is typically updated every day to display yesterday’s ice extent for both hemispheres. The Index relies on data that come from the DMSP F17 satellite. However, these data have not been reliable since early April; so the NOAA@NSIDC team has not been able to update the Sea Ice Index since 31 March 2016. Sea Ice Index processing uses an NSIDC NASA DAAC product, Near-Real-Time DMSP SSMIS Daily Polar Gridded Sea Ice Concentrations (NSIDC-0081), as input.
The SMAP Science Data System (SDS) has released updated NASA SMAP data products at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).
