Calibrating a large-extent high-resolution coupled groundwater-land surface model using soil moisture and discharge data

We explore the possibility of using remotely sensed soil moisture data and in situ discharge observations to calibrate a large-extent hydrological model. The model used is PCR-GLOBWB-MOD, which is a physically based and fully coupled groundwater-land surface model operating at a daily basis and having a resolution of 30 arc sec (about 1 km at...

Groundwater monitoring using grace and ERS satellite imager

This paper describes the initial stage of the assimilation of GRACE and ERS-1 and ERS-2 imagery with a global hydrological model. The outcome of the model will be evaluated with groundwater storage estimates based on GRACE data as well as with soil moisture estimates based on ERS-1 and ERS-2 scatterometer data.

VIERS-1 scatterometer model

In this paper a description is given of a physically based theoretical ocean backscatter model (called the VIERS-1 model) for intermediate incidence angles, and a comparison of its performance against the CMOD4 empirical model is made. The VIERS-1 scatterometer algorithm is based on a two-scale composite surface model which includes both...

A summary of the VIERS-1 scatterometer model

The VIERS-1 (Verification and Interpretation ERS-1) project has resulted in a new algorithm for the interpretation of the wind scatterometer, based on a physical model of air/sea/radar interaction in which the radar backscatter is calculated from wind and wave conditions. The model is inverted to obtain the wind from the radar backscatter. For...

Comparison of Microwave Backscatter Measurements and Small-scale Surface Wave Measurements Made from the Dutch Ocean Research Tower "Noordwijk"

To improve the understanding of the interaction between microwaves and water waves the VIERS-l project started in 1986 with the preparation of two wind/wave tank experiments and an ocean tower experiment. In February 1988, combined measurements of microwave backscatter, wind, waves and gas exchange have been carried out in the large Delft...
