Overview QA4SM

The Quality Assurance for Soil Moisture (QA4SM) service provides the user with:

An easy-to-use interface for comparing satellite soil moisture data against land surface models and the international soil moisture network
A traceble and consistent methodology for all comparisons
Various filtering and scaling options to assess the impact of these on the validation results
Traceable validation results in netCDF format and as visualisations (graphs and maps)

The overall aim is to bring together methodologies and protocols used for the validation and quality control of soil moisture data products and provider users with traceable validation results.

QA4SM is supported by the Austrian Space Application Programme.
