1.STSE 2.Objectives of today 3.Data availability 4.Reprocessing 5.RFI 6.Conferences & user meetings Introduction – SMOS mission status

DATA AVAILABILITY In summary … FROM 100% SCIENCE DATA AVAILABLE 1.ACQUISITION: no data loss due to overlap of 2 orbits so far 2.CALIBRATION: 1.68% 3.ANOMALIES: in Q4 2011: 0.016% loss of data, 0.342% degraded data since May (0.16)% loss of data, 2.70 (3.13) % degraded data  improvement due to CCU reset automatic procedure since Oct DATA PROCESSING: successfully processed to L1, L2SM, L2OS in 99.5% 5.NRT: delivered in 84.6 (84.2 in Q4/2012) % of the sensing time within the requirement of 165 minutes

REPROCESSING Status 1.Level 1 Reprocessing completed at the beginning of January (performance 1:20) Reprocessed data delivered to Brockmann cal&val portal and presently ingested and validated, distribution should start end February 1.Level 2 soil moisture Reprocessing completed at CNES/CESBIO Quality assessment ongoing: once completed reprocessed data will go to ESAC and Brockmann for distribution Dissemination will start end of February 2.Level 2 ocean salinity reprocessing and NRT conversion Has started w/c 6 Feb Expected to be completed by mid March Dissemination from Brockmann to start end of March

ECMWF reduced Gaussian Grid Number of nodes % of DGG grid % of DGG over land (threshold = 50%) T (100%) 13.3% (3.9%) T (100%) 32.2% (9.32%) Scientific requirements - full angular resolution - no averaging of TBs in the antenna reference frame - regular grid - land coverage Specifications: - T511 spectral resolution /N265 reduced Gaussian Grid - land points only - no interpolation, processor will use a “light” NRT AUX_DGG file UK Met Office “light” NRT BUFR product ESA Distribution NRT light product Distribution and product specification

RFI over oceans Continental regions are not the only ones affected by RFI Effect of RFI over Oceans: –Due to terrestrial RFIs that can affect larger areas, including of course neighboring oceans And also –Due to RFI emitters on board certain ships have been observed to emit in the protected band. RFI source observed during a SMOS descending pass over the Atlantic Ocean (BT Map)

RFI over oceans In-situ April 2010 ascendingApril 2010 descending Largest contamination  Northern hemisphere high latitude, particularly over the North Pacific and Atlantic oceans and during ascending passes How the RFI impact is seen? Quasi-circumpolar belt of high brightness levels (+30 K wrt ocean brightness temp  fresher waters) polluting data acquired North of 40°N latitude  RFI source: compatible with radar systems in Northern America and Southern tip of Greenland. Sea Surface Salinity (SSS)  Measurements of approx psu over open ocean (practical salinity unit) with psu accuracy after 1 month of data aggregation as requirement;  Variation of 1 K corresponds to 1 psu  Permanent RFI-induced signal > 0.1 K for 1 month is critical © N.Reul, Ifremer

RFI over Northern Latitudes SMOS brightness temperatures Feb 2011 Several radars are observed over the Northern Canadian border and at the tip of Greenland. The authorities from Canada and Greenland were informed, and requested to take actions. Feb 2011

RFI over Northern Latitudes SMOS brightness temperatures Feb 2012 Canada started to refurbish their equipment in autumn Greenland switched their transmitters off in March  At least 13 RFIs have been switched Off in the Northern Latitudes. However the few remaining RFIs can contaminate areas 3000 Km away from the original source, especially in passes descending towards North-America. Feb 2012

RFI over Southern Latitudes Southern hemisphere is far less RFI contaminated. So far, no RFIs has ever been detected in Antarctica.

RFI progress in Europe / World IN THE REST OF THE WORLD Canada has switched Off 11 radars US has switched off 13 RFIs 32 RFIs in China have disappeared, after some actions taken by the Chinese authorities. IN EUROPE

Conferences and meetings 1.SMOS session at Microrad in March 2.EGU SMOS session merged with “Remote sensing of soil moisture” and “Ocean remote sensing” 3.Ocean user meeting at EGU, Thursday 26 April 4.IGARSS 40 + abstracts for 3 invited sessions 5.Land user meeting planned
