GLOSCAL (Global Ocean Surface Salinity Calibration and
Validation) is a project retained as one of the ESA CalVal project.
Since 2006, it is supported by the TOSCA programm of CNES.
The project has two main objectives:
Analysis of the surface properties from in-situ data
This objective focuses on the vertical and horizontal SSS
structures at pixel scale, on the large scale variability and
climatology building, on the parameters controlling the SSS. It
includes the building of quality controlled in-situ databases.
Calibrate/validate SMOS data and improve the algorithms
This thematic relies on statistic analysis of brightness
temperature, biases and error sources estimation, improvement of
direct models and SSS algorithms, validation of SMOS SSS data by
a systematic and global comparison with available
reliable in-situ surface temperature and salinity data over the
global ocean within
short delay is
critical for the calibration and validation of SMOS. The work
presented here has been undertaken as a contribution to GLOSCAL.
on the Coriolis datasets and using ISAS objective analysis tool, a
near real time analysis system has been developed. It provides
gridded fields of sea surface salinity and temperature and the
corresponding in-situ dataset. In addition to research activities,
these products would be used to help the quality control of SMOS
satellite data, and to improve the algorithms and monitor sensor
drifts and biases.
