Changes in SMOS L3 TB

Category : CATDS, L3

Important information…

It was noticed by several users that our new RFI filter was overdoing things a bit (actually one of the flags was wrong) leading to a very reduced amount of available brightness temperatures.

We are working on this issue and already François and Stéphane have patched the bug and tests were carried out at CESBIO before implementation which is underway at CATDS.

The new products will have version number 310

Very soon the operational algorithm will release -less abusely filtered -  L3TB data (with more measurements thus) and we will also reprocess the whole data set (both L3TB and RFI).

NEW REPROCESSED SMOS DATA IS available at CATDS!

Category : CATDS, L3, Ocean

Dear  SMOS users,

All the SMOS L3 soil moisture, ocean salinity and common products, from January 2010 to April 2015, have been reprocessed. You can download those products from

a) CATDS with the usual procedure (if you do not have a password contact contact support@catds.fr to get one) or

b) through the SIPAD interface (http://www.catds.fr/sipad/).

Please NOTE :
- All the reprocessed products use the EASE2 grid.
- The CATDS processor’s version used is 300, which correspond to the DPGS version v620
- The reprocessed products are tagged RE04
- These reprocessed products are derived using the same algorithm as the one used in the CATDS real time processing, hence ensuring temporal continuity.
- A new RFI (radio frequency interference) probability product is available.

Very soon we will also make available 6 years of root zone soil moisture from SMOS

We appreciate your feed back so do not hesitate to contact us

Remember the SMOSDATA POLICY : The CATDS data are freely distributed. However, when using these data in a publication, we request that the following acknowledgement be given :
« These data were obtained from the « Centre Aval de Traitement des Données SMOS » (CATDS), operated for the « Centre National d’Etudes Spatiales » (CNES, France) by IFREMER (Brest, France) »

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.

SMOS 3rd training course is in full swing

Category : Training

The SMOS training course (3rd edition) is currently taking place at the ESA centre of Villafranca (ESAC) in Spain.
18 students from 14 countries together with 4 spectators are currently being « initiated » to the SMOS data in the very nice facilities of ESAC

The course is the third one and takes advantage of the release of the new version (V620) of the SMOS Data while covering both land and ocean science applications (see twitter account)

Next week, the Second post launch SMOS workshop will take place, also at ESAC. Stay tuned!
