Sentinel-1 snow depth assimilation to improve river discharge estimates in the western European Alps

<p>This data set contains model output presented in the following paper: &nbsp;I. Brangers, H. Lievens, A. Getirana, and G. J. M. De Lannoy. (2024). Sentinel-1 snow depth assimilation to improve river discharge estimates in the western European Alps. Water Resources Research. Under review.</p> <div>The model simulations were carried out in NASA's Land Information System (LIS), using the NoahMP v3.6 land surface model, forced with ERA5. The land surface model was coupled to the HyMAP routing algorithm to produce streamflow estimates. The data contains model results for the western European Alps for the period of 2015-2021 for two seperate cases. 1) The OL run: model run without assimilation of external observations; and 2) DA run:&nbsp; model run with the assimilation of Sentinel-1 snow depth observations.</div> <div>&nbsp;</div> <div>The zip-folders contain netcdf files for each day of the simulation period, for 1) the river discharge (_ROUTING),&nbsp;</div> <div>2) land surface model variables such as snow depth and SWE (_SURFACEMODEL_yyyy) grouped per year, and 3) variables related to the data assimilation such as the spread and innovations (_EnKF).</div>
