SMOS is 10 years old! Happy Birthday and many happy returns

Category : Satellite

Yes indeed!

10 years ago, early in the day with a completely overcast sky, SMOS soared into the skies.

And after that, dutifully and without almost no interruption, the mission has delivered an outstanding data stream … So congratulations to the project team who did this wonderful mission, and thanks to the operation teams who do the utmost to deliver the data in a timely and quality driven fashion…

So where are we after ten years? …

On top of all that was planned in terms of soil moisture and Sea surface salinity…

SMOS is used operationally at ECMWF in the IFS since June 2019

SMOS is used operationally to infer sea ice thickness, freeze thaw and also measures the internal temperature of the Antarctica Ice sheet…

SMOS is able to quantify high levels of biomass (300 t/ha) using the L-VOD this is also un precedented. It proved it ability to detect droughts in advance and help forecasting floods.

SMOS is used to improve rainfall estimates from satellite over both land and oceans, is unique for monitoring High winds (hurricanes and tornadoes)

Etc etc … I stop here as the list is too long and will get soon boring.  All I may add is that very novel uses are still coming out or on the verge of popping out (liquid water in snow and ice, green house gas emissions, …) so stay tuned.

Last but not least, we now have 10 years of continuous data at reach. We can start to study tele-connections, climate trends  indicators  or hints of them etc. The treasure box is far from being exhausted, believe me.

I may be biased but I do not think any mission can claim more results in so little time than SMOS -especially for an explorer missions. Did you realise we have already over 1400 publications  (h index of 68) in WoS? including 3 (and several more coming) in Nature journals and 20 highly cited papers?

So to make a long story short,

long life to SMOS !

Many thanks to all those who work every day with much dedication to provide us with the good data.

If as a user you have new results let us know! We like to keep abreast of all what is going on! This blog could be your sounding board

And let’s hope our decision makers will soon come to their sense and enable a SMOS/L- band radiometer follow mission to emerge – if only to satisfy the operational users!

Antarctica’s internal ice sheet temperature from SMOS

Category : CATDS, Data, L4

The new version of the internal ice sheet temperature estimated from SMOS over Antarctica is now available.This dataset is based on the combination of L-band (1.4 GHz) passive microwave observations with glaciological and emission models. The study highlights the potential of low microwave frequencies for investigating the internal temperature of the ice sheet.

SMOS Mission Extended to 2021!

Category : CATDS, Data, L1, L2, L3, L4, Non classé, Satellite

I am glad to inform you that yesterday the Program Board for Earth Observation (PB-EO) of ESA voted the SMOS mission extension following the ACEO (Advisory Committee for Earth Observation) review report:

« Member states’ delegations were very positive about both the achievements so far as well as the detailed plan being put forward for the extension. « 

CNES (the French Space Agency also funding the mission exploitation), has already granted funding until 2021 (actually 2019 with extension to 2021 pending PB-EO vote which we now have).

So, should everything go nicely with the satellite and platform, we have data guaranteed until  2021!

Congratulations and many thanks to all the actors of this success.

SMOS is now over 9 year old and still going strong by the way!
