A new empirical model of sea surface microwave emissivity for salinity remote sensing
[1] SMOS (Soil Moisture and Ocean Salinity) is a European Space Agency mission that aims at generating global ocean salinity maps with an accuracy of 0.1 psu, at spatial and temporal resolution suitable for climatic studies. The satellite sensor is an L-band (1400–1427 MHz) aperture synthesis interferometric radiometer. Sea surface salinity (SSS) can be retrieved since the brightness temperatur...
متن کاملSMOS: Measuring Sea Surface Salinity from Space
In May 1999, the European Space Agency (ESA) selected SMOS as an Earth Explorer Opportunity mission. One of its goals is the generation of global Sea Surface Salinity (SSS) maps. The sensor embarked is an L-band interferometric radiometer with full-polarimetric capability called MIRAS. The retrieval of SSS from microwave measurements is based on the fact that the brightness temperature (TB) of ...
متن کاملSea surface signature of tropical cyclones using microwave remote sensing
Measuring the sea surface during tropical cyclones (TC) is challenging due to severe weather conditions that prevent shipboard measurements and clouds which mask the sea surface for visible satellite sensors. However, sea surface emission in the microwave L-band can penetrate rain and clouds and be measured from space. The European Space Agency (ESA) MIRAS L-band radiometer on the Soil Moisture...
متن کاملIntercomparison of Surface Roughness Parameterizations for Soil Moisture Retrieval
Soil moisture plays a key role in many hydrological and agricultural processes because it controls the water and heat energy exchange between the earth and the atmosphere. Addressing the need for routine global surface soil moisture maps, the European Space Agency (ESA) launched the Soil Moisture and Ocean Salinity (SMOS) mission in 2009. It provides L-band microwave brightness temperature obse...
متن کاملEvaluation and Improvement of SMOS and SMAP Soil Moisture Products for Soils with High Organic Matter over a Forested Area in Northeast China
Soil moisture (SM) retrieval from SMOS (the Soil Moisture and Ocean Salinity mission) and SMAP (the Soil Moisture Active/Passive mission) passive microwave data over forested areas with required accuracy is of great significance and poses some challenges. In this paper, we used Ground Wireless Sensor Network (GWSN) SM measurements from 9 September to 5 November 2015 to validate SMOS and SMAP Le...
