take information for EFAS from the following pages: EFAS static data & Static data files
what to add? e.g. Upstream area, Flood thresholds, etc....
In order to interpret CEMS-Flood (EFAS & GloFAS) output in a correct way, you will need various auxiliary data, also referred to as 'static' data. These data are part of the EFAS and GloFAS setups of the LISFLOOD model.
EFAS Auxiliary Data
These files denote the total upstream area for each river pixel, expressed in m2. This is defined as the catchment area for each river segment, meaning the total area that contributes with water to the river at the specific grid point. The upstream area always includes the area of the pixel. The upstream area is provided in the netCDF file if you retrieve the data from CDS and choose the format netCDF. You can also download the upstream area file as netCDF below:
| Versions | Version Date | File |
|---|---|---|
| EFAS version 3.0 and below | Version 2.0 Released 2018-10-10 12 UTC Version 3.0 Released 2019-05-13 12 UTC | |
| EFAS version 3.5* | Version 3.5 Released 2020-03-05 12 UTC | |
| EFAS version 4.0 | Version 4.0 Released 2020-10-14 12 UTC |
The river network changed slightly for EFAS version 3.5, therefore there is a new upstreams area file.
This file denotes the mean elevation for each pixel in the EFAS domain, expressed in m above sea level. The file can be downloaded as NetCDF here.
The auxiliary/static files you need to calculate soil moisture index are here.
GloFAS Auxiliary Data
take information for GloFAS from the following pages: GloFAS available data (upstream area)
In order to interpret the GloFAS output in a correct way, you will need static data that describes the model setup. This file denotes the total upstream area for each river pixel, expressed in m2. The upstream area is defined as the catchment area for each river segment, in other words, the total area that contributes water to the river at the specific grid point. The upstream area always includes the area of the pixel. You can download the upstream area file as netCDF here.
