Why is there some gaps in the data in 2010 ?

• SMOS nominal acquisitions started on 12/01/2010, just after the first full calibration of the instrument. Data acquired prior to this date and since 17/11/2009 (instrument switch on) can't be used.

• From 20/04/2010 to 26/04/2010, an electrical stability test was performed on the instrument. During this period, no data were acquired.

• From 25/12/2010 to 02/01/2011, the arm B suffered from abnormal thermal regulation. The data are degraded and can't be used.

Due to the temporal window used, the Soil Moisture level 3 products are unavailable a bit more around those gaps.
