Dear colleague,

With regards to your potential contribution to the Special Issue on SMOS in Remote Sensing of Environment, we would like to notify you that the deadline for full paper submissions has been extended until 31st July 2015. Please be aware that this deadline change is final and no exceptions will be allowed after this date.

In case you have already submitted your paper, please disregard this message.

To submit your paper, please go to and select the option ‘submit paper’ from the menu bar near the upper left corner of the page. During the submission process, please make sure to select ‘SMOS 5 Years’ in the dropdown menu when choosing the article type, as demonstrated in the attached image.

Accepted papers will be published online as soon as possible following a final editing procedure by the Publisher. Once again, we encourage you to critically check your list of authors against the RSE guidelines on authorship ( to ensure appropriate representation of effort.

We look forward to receiving your contributions.

Yours sincerely,
Susanne Mecklenburg

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!

The 2nd SMOS SCIENCE CONFERENCE (25-29 May 2015) and the SMOS TRAINING COURSE (18-22 May 2015) will take place at ESA-ESAC, near Madrid (Spain).

For further information on both events please see

The deadline for submission of abstracts for the SMOS science conference and applications for the SMOS training course is 16 January 2015.

The 2nd SMOS Science Conference will be jointly organised by ESA, CNES and SMOS-MODE.

By 2015, the SMOS mission will have been in orbit for more than five years, providing a continuous stream of high quality data products. Being a water cycle mission, SMOS observations have been used by rather distinct science communities addressing oceanography, land surface hydrology, and meteorology over a wide range of applications. The focus of this conference will deviate from previous events in that the emphasis will be on applications of SMOS data, including operational services, the development of novel data products, the synergistic use of SMOS data with other data sources and the potential of SMOS data for the generation of long-term data sets. The workshop will also cover common themes such as the quality of the Level 1 data products and calibration and validation activities.

The 2nd SMOS Science Conference will be preceded by a SMOS Training Course on 18-22 May 2015, organised by CESBIO and held as well at the ESA-ESAC premises near Madrid. The course will provide an opportunity to learn how to work with level 1 (brightness temperature) and level 2 (soil moisture and ocean salinity) data provided by the SMOS mission. The deadline for applications is 16 January. To submit your applications please go to –> Training Course and use the link on the bottom of the page.

LEWIS is on the move! Part One

Category : Cal/Val, Data, ground measurements

Back in 2002 we had a high quality ground based radiometer built by ONERA (Jean Claude Poussière and François Lemaître) with CNES funding (TOSCA) (see Lemaitre et al, IEEE). This radiometer was installed in a fallow field south of Toulouse together with classical equipment to monitor the various meteorological and soil variables (see de Rosnay et al, 2006). In 2011 a COSMOS probe was added to the set up  (for more info see here).


LEWIS during tests before implementation (2002)

From January 2003 to last year the set up worked almost continuously (there was one big maintenance though) providing a wealth of measurements in all possible conditions (wet years, dry years, snow, freezing soils, storms etc….) with L band dual polarised data acquired at angles from 20 to 60° on both bare soil and fallow land.  Moreover, on several occasion we did specific campaigns  for instance to alter roughness over a large range of values etc). This gave way to a number of publications and helped improving LMEB and the L2 retrieval algorithm sub models…

The data set is available for other research purposes. Just ask if you need part of the data set ( During this whole period, with only one maintenance stop, the instrument worked extremely well with a remarkable stability and accuracy. It even went through a bush fire unscathed!

But after 9 years in operation we decided it might be useful to go to other places and, in collaboration with ONERA (F Lemaître), INRA ISPA (Jean Pierre Wigneron as always since start !) and LTHE (Thierry Pellarin) we looked for, and found, an adequate location close to …


The idea was to find a site where we could have more occurrences of snow and cold weather but mainly a set up offering a capacity to have well characterized mixed footprints.

Finally Arnaud and Thierry found a place satisfying all criteria close to Grenoble and we started the move … The first step was to refurbish LEWIS and replace the filters (to reduce RFI risks) this was promptly done in 2012. More complicated was setting up the site as it is located in altitude and we had to have a platform overhanging the valley built, we had to have energy brought to the site and to develop the mechanisms to point the antenna.

Testing the controllers in a warmer (!??) and safer place than on top of the cliff!

This was done during this last winter but we then had to wait for the of the winter and snow melt before we coudl transport and finally implement our equipment on site …

This will be described in part two together with the first plots
