Salinity variability from ARGO and SMOS data

Category : Data, L2, L3, Ocean


By N. Kolodziejczyk et al. (see Mercator Ocean-Coriolis Quaterly Newsletter)

Using a 4-year time-series of SMOS SSS data (mid-2010 to mid-2014) and the global Argo array of in situ measurements as reference data base, a statistical approach and Optimal Interpolation are used to characterize and to correct a large part of the biases and reduce the noise. The results are promising and it shows the strong complementarity between SMOS and Argo data.

Differences between SMOS L3 and SMOS OI is identified by a gray vertical segment. The color of the circle refers to the merchant ship (Black: M.S. Colibri; red: M.S. Toucan, blue: M.S.

End of of the SMOS fortnight at ESAC !!

Category : CATDS, Tools, Training

A very busy two weeks at ESAC have just finished.

First a training course took place at ESAC during one week (May 18-22). It was the third SMOS training course but this time ESA took care (very efficiently!) of the logistics and provided us with very nice facilities (thank you Antonio!!)

This training course was aimed at newcomers wanting to learn how to use SMOS. With lectures intersped with practicals the students (18) were intitated into the different SMOS levels. The course also included a visit of the ESAC facilities together with a fine « BBQ ».


Some of the students stayed on to take advantage of the SMOS Conference which was also a success . The presentations covered all the SMOS aspects together with presentations and posters of equivalent missions (Aquarius and SMAP) recent results and synergisms. Evening were busy with spontaneous picnics and a gorgeous banquet

The presentations will be made available by ESA on its SMOS conference site.
