L3 CATDS Performances

SMOS L3 CATDS  Soil moisture retrieval algorithm

Soil moisture processor performances :

Filtered brightness temperature records :

Brightness temperature records filtered (not used) by the soil moisture processor.

Total attempted retrievals :

The figure shows the total attempted retrievals. The retrieval over attempted nodes can be successful or fail. Check next figure for successful retrievals. 3 days and 18 days moving average are shown.
Plot 1: number of attempted retrievals
Plot 2: percentage of attempted retrievals from total potential nodes

Total successful retrievals :

The figure shows the total successful retrievals. Check next figures for successful retrievals over specific surface types. 3days and 18 days moving average are shown.
Plot 1: number of successful retrievals
Plot 2: percentage of successful retrievals from total potential nodes

Successful retrievals over soil cover & low vegetation nodes :

Successful retrievals over forest cover:

Successful retrievals over frost cover : (preliminary, verification is needed)

Successful retrievals over ice:

Successful retrievals over mixed (wet, dry) snow:

Successful retrievals over open water:

Successful retrievals over wet snow :

Successful retrievals over wetlands :

Successful retrievals over frost :

Successful retrievals over heterogeneous surfaces:

Successful retrievals over heterogeneous open water:

Successful retrievals over mixed (dry, wet ) snow pollution :

Successful retrievals over wet snow pollution :

Successful retrievals over barren cover (rocks, …) :

Still need more detailed analysis ?
The following plots show the number and percentage of successful retrievals over soil cover for different levels (richness) of retrievals. The richness of retrieval depend on type of model and level of optical thickness.


The same for forest cover :
