The use of a semi-empirical emissivity model for a rough estimation of sea surface salinity from an airborne microwave radiometer

open access: yesScientia Marina, 2008
In preparation for the European Space Agency SMOS (Soil Moisture and Ocean Salinity) satellite mission, radiometric and oceanographic measurements were performed in December 2000 and January 2001 and in November 2001 from a fixed platform in the NW ...

Effect of Ag Addition on the Gas-Sensing Properties of Nanostructured Resistive-Based Gas Sensors: An Overview

open access: yesSensors, 2021
Nanostructured semiconducting metal oxides (SMOs) are among the most popular sensing materials for integration into resistive-type gas sensors owing to their low costs and high sensing performances.

Impact of correlator efficiency errors on SMOS land-sea contamination [PDF]

open access: yes, 2015
Land-sea contamination observed in Soil Moisture and Ocean Salinity (SMOS) brightness temperature images is found to have two main contributions: the floor error inherent of image reconstruction and a multiplicative error either in the antenna ...
