SMOS REPROCESSED Level 2 DATA (V6) now available

Category : Data, L1, L2, Ocean

Dear SMOS data user -

We would like to inform you that the reprocessed level 2 soil moisture and sea surface salinity data are now available on the new ESA SMOS Online Dissemination service:

This release aligns the Level 2 soil moisture and sea surface salinity data available operationally already since May 2015 with the reprocessed data archive: SMOS data users now have a complete v6 data set available.

The algorithm evolutions implemented in the v6 data set are described in the respective Algorithm Theoretical Baseline Documents (ATBDs) and in the read-me-first notes: We would like to encourage all users to familiarise themselves with the read-me-first notes before using the data.

The level 2 reprocessed data products are available on the new ESA SMOS Online Dissemination service accessible here ( The new service allows to access data by https and ftp/ftps transfer protocols for all registered ESA EO Single Sign-On (EO-SSO) users. The online service facilitates the data access with enhanced functionality for data navigation and selection by data type, acquisition time, geographical area and data format (i.e. ESA Earth Explorer (EEF) or NetCDF format).

SMOS level 1 brightness temperature data and  ECMWF auxiliary products are also available from the new ESA SMOS Online Dissemination service.

For further details on how to access the SMOS data  and how to register as ESA EO_SSO please

Kind regards

Susanne Mecklenburg

SMOS RSE special issue deadline postponed

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
On behalf of the editors for the Special Issue on SMOS in RSE

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.

New RFI Maps from Aquarius

Category : Data, L1

The Aquarius mission is also trying to identify and Flag RFIs.

Paolo de Matthaeis is producing monthly RFI maps for BOTH the active and passive L band systems on board Aquarius they can be seen here for the radiometer and here for the scatterometer.

It is interesting to compare them to the SMOS ones even though they are not established exactly in the same way (but we are working on it!) We see for instance that over land the number of RFI is higher for Aquarius, probably due to a larger bandwidth (TBC) collecting more out of band (OoB) emissions.

Comparing these RFI maps is not really possible quantitatively as they do not show the same features , but we can never the less see the high correlations between the two radiometer estimates as well as the non negligible impact on active measurements.

For more details go here for Aquarius and there for SMOS

SMOS probability of RFI for 15 Days in June 2013 – Ascending orbits only

Finally we are also producing maps of emitter characterization at any given time, giving their apparent strength in K, the number of time they were observed and their location (1-7 km accuracy). An example is shown below.

All this new stuff will be posted on the blog soon… Stay tuned
