The distribution and variability of salinity in the world's oceans is a key parameter to understand the role of the oceans in the climate system. SSS can be retrieved from the brightness temperature of Soil Moisture and Ocean Salinity (SMOS) measurements and Auxiliary data SMOS satellite provided. This paper provides a new statistical approach for modeling SSS for SMOS data to improve the accuracy...
Sea surface roughness and foam have great influence on the retrieval accuracy of sea surface salinity (SSS) from satellite measured L-band brightness temperature (TB). A lot of work need to be done to improve the SSS retrieval accuracy especially using the forward model to reduce the error induced by sea surface roughness and foam. In this paper, seven factors, whitecap coverage, significant wave...
The sea surface salinity (SSS) is a key parameter in monitoring ocean states. Observing SSS can promote the understanding of global water cycle. This paper provides a new approach for retrieving sea surface salinity from Soil Moisture and Ocean Salinity (SMOS) satellite data. Based on the principal component regression (PCR) model, SSS can also be retrieved from the brightness temperature data of...
With the perspective of discriminating some regions particularly suited or unsuited to sea surface salinity retrieval studies by satellite data, the horizontal and vertical Sea surface salinity variability for different time scale is calculated in South China Sea area from 2005 to 2014. It gives a variability with less than 0.1psu in most areas in space resolution of 1°×1° for short time scales. But...
After almost 5 years of SMOS launched, accuracy of satellite SSS measurements is evaluated/validated in most areas. But In South-China Sea area (4 ° N-25 ° N, 105 ° E-125 ° E), few calibration/validation efforts is made in this area. In this paper we will validate the satellite (SMOS/Aquarius) derived SSS measurements based on moored buoys and ARGO in-situ measurements. For SMOS SSS measurements,...
The study of sea surface salinity (SSS) plays an important role in the marine ecosystem, estimation of global ocean circulation and observation of fisheries, aquaculture, coral reef and sea grass habitats. Three statistical methods without considering the physical effects of the input parameters are proposed to calculate the sea surface salinity from SMOS measured TB values and associated auxiliary...
