Estimating the global terrestrial hydrologie cycle through modelling, remote sensing and data assimilation
Estimating the global terrestrial hydrologie cycle through modelling, remote sensing and data assimilation
This study focuses on water budget estimation using satellite-only data products over 10 continental river basins. A non-satellite merged product (which includes model, in situ and re-analysis data) is also used to evaluate each satellite precipitation (P) and evapotranspiration (ET) product. The water budget estimated from the satellite-only products is found not to close the budget over the river basins. A water budget closure scheme is employed where the budget non-closure error from each water budget component is estimated, and closure is obtained by redistributing the non-closure error using these error statistics. It is found that the satellite precipitation product carries most of the non-closure error.

Abstract
This study focuses on water budget estimation using satellite-only data products over 10 continental river basins. A non-satellite merged product (which includes model, in situ and re-analysis data) is also used to evaluate each satellite precipitation (P) and evapotranspiration (ET) product. The water budget estimated from the satellite-only products is found not to close the budget over the river basins. A water budget closure scheme is employed where the budget non-closure error from each water budget component is estimated, and closure is obtained by redistributing the non-closure error using these error statistics. It is found that the satellite precipitation product carries most of the non-closure error.
