The PO.DAAC is pleased to announce the release of the version 4.0 SMAP Sea Surface Salinity (SSS) data from Remote Sensing Systems (RSS). Enhancements over the previous release include:

* Improved land correction allows for salinity retrievals within 30 – 40km of the coast. The land correction uses a land correction table at 0.125 degree spatial resolution. The land emission that is used in the land correction is based on SMAP TB.

* Replacement of the previous NCEP sea-ice mask with one based on RSS AMSR-2 and implementation of a sea-ice threshold of 0.3% (gain weighted sea-ice fraction).

* Revised solar flagging that depends on glint angle and wind speed.

* Inclusion of estimated SSS-uncertainty in the L3 products.
