In this section you will find metadata regarding the GloFAS data. This data will help you understand how the data was produced, which data is available and what the limitations are. For an explanation of the the terminology used in GloFAS, please see the CEMS glossary.
Here is a brief overview of the GloFAS data made available to the public. For a full overview of the GloFAS system, please go to the dedicated pages on the GloFAS web site http://www.globalfloods.eu/. You will find information on the latest releases here: 01. GloFAS operational system. Note GloFAS 30-day real-time forecasts over the European domain are currently not publicly available.

GloFAS 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. Upstream area is defined as the catchment area for each river segment, in other words 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. You can download the upstream area file as netCDF here:
