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)
QA4SM was created thanks to support of the Austrian Space Application Programme. From 2021 on the application is also supported by the European Space Agency.
