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 http://ees.elsevier.com/rse/ 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 (http://www.elsevier.com/journal-authors/ethics) to ensure appropriate representation of effort.

We look forward to receiving your contributions.

Yours sincerely,
Susanne Mecklenburg
On behalf of the editors for the Special Issue on SMOS in RSE

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.

New SSS Thematic Research Products available from CATDS/Ifremer Expertise Center

Figure illustrating the content of the new CATDS/CEC IFREMER Level 4a weekly 1/2° products

4 types of new level 4 « research » products were developed by the CATDS/IFREMER expertise center for salinity (CATDS/CEC-OS SMOS Level 4) and are now accessible for download.

These new Level 4 research products are weekly (7 days) composite at 50 km resolution. The products coverage is May 2010-December 2014.

Level 4a include weekly SMOS SSS biased-corrected at large scale (10°x10°) using monthly in situ OI (ISAS) fields.In addition, these L4a products also include an ensemble of geophysical parameters derived from well-acknowledged products in the scientific communities that are useful for synergistic science applications using SMOS data. These include Sea Surface Temperature (ECMWF), surface currents (OSCAR), rain (TRMM & CMORPH), evaporation (OAFLUX), surface wind stresses (ASCAT), mixed-layer depth from In situ OI(APDRC), Surface salinity from in situ OI (ISAS) and salinity at the base of the mixed-layer depth estimated also from In Situ OI.

-Level 4 a synergistic products:

These products include key geophysical variables to analyse the salinity budget in the upper ocean mixed layer. These include:

-SSS from SMOS & in situ OI (ISAS),

-SST from ECMWF,

-wind speed modulus (ECMWF)

-wind stress components (ASCAT),

-ocean surface current components (OSCAR),

-Evaporation (OAFLUX),

-Precipitation (TRMM3B42 & CMORPH),

-Mixed Layer Depth (In situ OI),

-Salinity at the base of the mixed-layer

These fields are averaged or cummulated in time -or interpolated- over the week of the SMOS L4a SSS and gridded at the same 1/2° spatial resolution.


In addition we include the following thematic datasets:

L4aSSS In situ Match-up products

Quality controlled surface salinity and temperature measurements from Argo floats, ship TSG, surface drifters, Tropical Moorings and sea seals data provided by the Coriolis, GOSUD, SAMOS and LOCEAN  data centers are collected weekly over each of the L4 composite product period and co-locatized with SMOS L4a SSS products.

Supplementary data are provided with the in situ match-up database such as vertical profiles of S and T if available, co-localized ASCAT and TRMM3B42 data, etc..

A match-up database file per in situ sensor type is provided for each week of the L4a products.

L4b density products

L4b density products are satellite surface density fields. These surface density fields are so-called   »CATDS/CECOS Ifremer SMOS Level 4c research products » and are weekly composite products of surface density at a spatial resolution of 0.50° x 0.50° deduced from the L4aSSS data and ECMWF SST data. In addition,  the products include:

-mean sea level anomalies from AVISO

-OSCAR currents components

-Wind stress components from ASCAT

L4c anomaly products

L4c products are Anomaly fields. These surface salinity anomaly fields are so-called   »CECI-OS Ifremer SMOS Level 4c SSSA research products » and are weekly composite products at a spatial resolution of 0.50° x 0.50° deduced from the L4aSSS data. The anomalies are evaluated by removing an annual-averaged reference weekly composite field evaluated by averaging the SMOS L4aSSS data over 5 years (2010 to 2014).

weekly anomalies for various thematic fields are also included such as:

-ECMWF sst anomalies

-Cummulated Evaporation anomalies from OAFlux

-Cummulated Precipitaions anomalies from TRMM3B42

-Cummulated Precipitation anomalies from CMORPH

-Mixed layer depth anomalies from APDRC

-Wind stress components anomalies from ASCAT

-Anomalies of the Salinity at the base of the Mixed Layer

-OSCAR currents components anoamlies

-ISAS temporally interpolated monthly SSS & SST fields anomalies

-surface density anaomalies

-MSLA

The data and associated documentation can be accessed through the catds ftp portal at:

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!
