Description:

The objective of this project is to investigate the spatial scaling of remotely sensed soil moisture and rainfall based on different remote sensing products. The project aims at developing a methodology which allows for up- and downscaling of remotely sensed observations, and to assess the uncertainty in the obtained products. Deriving scaling laws and modelling the uncertainty on scaled products are both of uttermost importance when such data are applied in hydrological model studies.

Within this 4-year project different research items can be discerned.
Concerning soil moisture:

Scaling based on in-situ measurements
Hydrogical modelling of soil moisture fields
Remote sensing of soil moisture based on different sensors with varying spatial resolution
Investigation of sub-pixel statistics
Derivation of scaling laws and assessment of uncertainty

Concerning rainfall:

Analysis of different spatial rainfall products
Derivation of scaling laws for rainfall
Modelling missing data based on rainfall observations at different spatial resolution
Modelling uncertainty on scaled products
