Compared 3 datasets:
Dataset 1:
ESA CCI SM combined (v05.2, sm) [Filters: Variable in valid geophysical range; Data with no inconsistencies detected (flag = 0); ]
Dataset 2:
ESA CCI SM combined (v04.7, sm) [Filters: Variable in valid geophysical range; Data with no inconsistencies detected (flag = 0); ]
Reference:
ERA5 (v20190613, swvl1) [Filters: Soil not frozen; Variable in valid geophysical range; ]
Validated globally.
Validation period / temporal filter: Jan. 1, 1978, midnight UTC to Dec. 31, 2019, 11:59 p.m. UTC.
Validation metrics calculated from absolute values.
Triple collocation analysis was activated.
Scaling reference: ERA5 (v20190613, swvl1) [Filters: Soil not frozen; Variable in valid geophysical range; ]
Scaling method: Mean/standard deviation.
Processing took 1139 minutes (wall time).
0% (0 of 244450) of the processed locations (grid points) produced errors during calculation.
