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). The following NASA SMAP Levels 1-3 data have been updated:
New data access options are available for the MEaSUREs Greenland Monthly Image Mosaics from MODIS, Version 1 data set accessible from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The direct download location for this MEaSUREs (Making Earth System Data Records for Use in Research Environments) data set has changed, and both temporal searching and ordering are now available through NASA Earthdata Search using the Package Options button on the data set Web page.
Version 1.3 of the MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) for the AMSRE, F16, F17, F18 and F19 sensors. The changes in this minor version update vary depending on the sensor and are listed by sensor in Table 11 of the user guide.

The B02 update corrects an error that caused only half of each swath to be processed. Processing with the B02 algorithm began on May 03 2018. Data from July 07 2012 through May 02 2018 will be reprocessed.
The NASA IceBridge POS/AV L1B Corrected Position and Attitude Data data set, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated through 19 April 2018. This data set contains georeferencing data from the Applanix 510 POS AV system flown with the Digital Mapping System (DMS) and other instruments over Greenland and Antarctica. Data parameters include latitude, longitude, altitude, velocity, roll, pitch, and heading.
The NASA IceBridge Snow Radar L1B Geolocated Radar Echo Strength Profiles data set, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated through 25 November 2017. This data set contains radar echograms taken from the Center for Remote Sensing of Ice Sheets (CReSIS) ultra wide-band snow radar over land and sea ice in the Arctic and Antarctic. The data were collected as part of Operation IceBridge funded campaigns.
The ASO L4 Lidar Snow Depth 50m UTM Grid data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) from 08 February 2016 to 16 August 2017.
