7 September 2012 SMOS shows realistic salinity fronts in the North Atlantic >>

24 April 2012 Ocean salinity data have been reprocessed applying the continuously ameliorated L1-Level and L2- level processors by argans and the ESL (expert support laboratories) for all the data so far existing. Now, all data products are generated the same way. Details on argans web site.

1 June 2009 – ESA's next Earth Explorer, SMOS, has just passed the all-important Flight Acceptance Review, signifying that all the elements that make up the mission are in place for launch later this year. The satellite can now be prepared for its journey to the Plesetsk Cosmodrome in northern Russia. >>more information

27 April 2009 – Following confirmation from Eurockot Launch Services that they will launch ESA's SMOS mission on 9 September this year, the satellite has just been taken out of storage – providing an opportunity for the media to view the satellite before it is prepared for shipment to the launch site in Russia. >>more information

17 March 2009 – GOCE successful launched. With this launch, a new chapter in the history of Earth observation in Europe has begun. GOCE is the first of a new family of ESA satellites designed to study our planet and its environment in order to enhance our knowledge and understanding of Earth-system processes and their evolution, to enable us to address the challenges of global climate change. In particular, GOCE will measure the minute differences in the Earth’s gravity field around the globe. SMOS will be the next satellite in ESA's LIVING PLANET Programm. >>more information

11 - 13 March 2009 – SMOS SVRT Workshop in Lisboa. The participants of the workshop presented former and planed activities within the SMOS CAL/VAL projects. Campaigns were planed and discussed, SMOS Tools for data viewing and first analyses presented and demonstrated. Due to the broad SMOS launch window from July to October the optimal date for the CAL/VAL campaigns is discussed - to realise it during the commissioning phase or in spring 2010.

24 January 2007 - Beginning of March a German-Finnish seaice measurement campaign will take place in the Bay of Bothnia as part of the SMOS preparatory campaigns. The measurements and their interpretation are going to be done by scientists of the Institute of Environmental Physics of the University of Bremen, the Alfred Wegener Institute of Bremerhaven and the Technical University of Helsinki. During the campaign seaice measurements of the L-band radiometers EMIRAD and HUT2D carried by a Skyvan aircraft are going to be compared to measurements of an electromagnetic ice thickness sensor from a helicopter. Three different flight scenarios are envisaged corresponding each to different sampling conditions. Aim of these measurements is the validation and adaptation of existing ice emissivity models to the L-band frequency region, as well as determining which physical ice parameters can be retrieved from an L-band signal.

7 Dezember 2006 -The first measurements of the down-sized MIRAS instrument (AMIRAS - Airborne MIRAS) have been made during a flight campaign of the technical university of Helsinki. The results demonstrate impressively the functionality of the novel measurement principle of MIRAS. The dynamical range of the L-band signal over land and ocean has been completely covered. >> read full story

9 October 2006 - The Proteus platform is ready for integration with the MIRAS payload which will be carried out after the MIRAS construction has been completed by EADS-CASA. The platform provides the 'Infrastructure' to the mission. >> read full story

17 August 2006 - A significant milestone in the framework of the SMOS mission has recently been achieved with the completion of the new Finnish HUT-2D airborne instrument and the subsequent accomplishment of two major results. >>read full story

27 June 2006 - As part of the engineering process an important document defining all the interfaces between the SMOS spacecraft and the Rockot launch vehicle was recently formally signed at ESA-ESTEC in the Netherlands. >> read full story

31 January 2006 - A reduced SMOS MIRAS instrument approaches the end of its development. It is an airborne sensor to be used during the mission to make measurements similar to SMOS. The first flight campaign is planned for this summer.

15 December 2006 -The SMOS payload passes a milestone with the successful termination of the “Critical Design Review” the ESA. During a two-month Review phase each detail of the sensor was inspected carefully and an all clear was given for the final production phase of the sensor and the assembly with the platform and testing of the total structure.
