Reprocessing Complete for SMAP Data

The SMAP Science Data System (SDS) has completed reprocessing of the NASA SMAP Level-1B, -1C, -2, and -3 data products to Validated Version 3. Additionally, SMAP Level-4 products have been reprocessed to Validated Version 2.

During reprocessing, Level-1B, -1C, -2 and -3 data spanning the time period 19 November 2015 to 02 February 2016 were regenerated and replaced due to an issue with a spacecraft ancillary input file. The affected files end with R13080_001.h5. Users who currently have files within this date range may want to download the replacements, as portions of the right edge of the swath near 270° antenna azimuth were erroneously set to fill values.

Changes implemented in these versions are summarized on the SMAP Data Versions page: https://nsidc.org/data/smap/data_versions
