Erroneous data in the RSS SMAP Version 4.0 salinity processing have appeared for the time period February 4-17, 2020, affecting both L2C files and 8-day L3 files. The reason is a bad HYCOM salinity ancillary file for February 9.

This affects the salinity algorithm, as HYCOM ancillary data is used for the target calibration. A new HYCOM model was obtained and the results were updated. Please download the updated files if you have used RSS SMAP V4.0 data for the following period. The specific affected files are listed below:
