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.

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:
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 a netCDF file here: dem.nc. |

EFAS Horizontal Resolution
LISFLOOD projection
The LISFLOOD operational model is setup over Europe with the spatial resolution of 5 * 5 km with the geographical projection is the INSPIRE compliant ETRS89 Lambert Azimuthal Equal Area Coordinate Reference System (ETRS-LAEA). ETRS-LAEA is a single projected coordinate reference system for the pan-European area. It is based on the ETRS89 geodetic datum and the GRS80 ellipsoid, and is the recommended projection for pan-European statistical mapping at all scales or for other purposes where true area representation is required. Its defining parameters can be found here.
Proj4 format: Proj4js.defs["EPSG:3035"] = " +proj=laea +lat_0=52 +lon_0=10 +x_0=4321000 +y_0=3210000 +ellps=GRS80 +units=m +no_defs "
GloFAS Auxiliary Data

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. |
