The Aquarius end-of-mission (Version 5) salinity data set was released in December 2017.
This article gives a comprehensive overview of the main steps of the Level 2 salinity retrieval …

Since 2009, three low frequency microwave sensors have been launched into space with
the capability of global monitoring of sea surface salinity (SSS). The European Space …

Satellite-based passive microwave remote sensing typically involves a scanning antenna
that makes measurements at irregularly spaced locations. These locations can change on a …

The sea surface temperature (SST), ocean wind speed (OWS), and sea surface salinity
(SSS) are fundamental variables for understanding, monitoring, and predicting the state of …

The Soil Moisture Active/Passive (SMAP) microwave radiometer is a fully polarimetric L-
band radiometer flown on the SMAP satellite in a 6 AM/6 PM sun-synchronous orbit at 685 …

During the post-launch Cal/Val Phase of SMAP there are two objectives for each science
product team: 1) calibrate, verify, and improve the performance of the science algorithms …

Soil moisture (SM) plays an important role for understanding Earth's land and near-surface
atmosphere interactions. Existing studies rarely considered using multi-source data and …

Polarimetric microwave radiometers such as SMAP are capable of measuring the fourth
Stokes parameter in brightness temperature over the Earth surface. The value of this …

Cold Sky Calibration is an important tool in the calibration of the SMAP radiometer. It is used
to assess the absolute calibration and its temporal drift. We will present the results of 7 years …
