[30-Dec-16] This is the product specification document for the Level 2B (L2B) passive Sea Surface Salinity (SSS) and Wind Speed (WSPD) product for the Soil Moisture Active Passive (SMAP) project.
[13-Sep-16] SMAP sea surface salinity (SSS) V2.0 validated release data from Remote Sensing Systems
. The near-polar orbit of SMAP allows for complete global coverage of the oceans in 3 days with a repeat cycle of 8 days. The RSS SMAP SSS V2.0 validated release contains 3 products: Level 2, Level 3 8-day running averages, and Level 3 monthly averages. All files are in netCDF4 format and are CF compliant.
[24-Dec-15] Aquarius is a combined active/passive microwave (L-band) instrument designed to map the salinity of global oceans from space. The specific goal of Aquarius is to monitor the seasonal and interannual variation of the large scale features of the sea surface salinity (SSS) field of the open ocean (i.e. away from land).
[22-Dec-15] This memo presents a method for formally assessing random and systematic uncertainties in the Aquarius salinity retrievals.
[31-Dec-13] The SMAP Handbook was produced in 2013 as a compendium of information on the project near its time of launch. The SMAP Science Definition Team and Project personnel wrote this volume together to provide the community with the essential information on programmatic, technological, and scientific aspects of the mission.
[18-Feb-13] This report documents the Aquarius sea surface salinity measurement error statistics and some residual errors in the V2.0 data release. We also document the effect that changes in the science data processing since V1.3 have on the error statistics by comparing V1.3 with V2.0 results.
