Recent delivery from the US Navy of the SSMIS passive microwave data that several sea ice and brightness temperature products use has become more sporadic. The Defense Department has informed NSIDC that they will reduce the priority of processing the SSMIS data, resulting in likely daily data gaps. NSIDC will explore switching to a different sensor, the JAXA Advanced Microwave Scanning Radiometer 2 (AMSR2). However, this transition will take time. We apologize for any inconvenience and appreciate your patience during this transition.
The National Snow and Ice Data Center (NSIDC) is pleased to announce the publication of two new data sets, the Near Real-Time MODIS/Terra L3 Global Daily 500m SIN Grid Snow Cover, Snow Albedo, and Snow Surface Properties, Version 1 and Historical MODIS/Terra L3 Global Daily 500m SIN Grid Snow Cover, Snow Albedo, and Snow Surface Properties, Version 1.
