GloFAS relies on hydro-meteorological observations, numerical weather predictions and satellite data in order to produce, enrich and validate its products, resulting in improved accuracy and reliability.
In-situ monitoring of discharge data is crucial for GloFAS model calibration and validation.
Discharge data can be used to improve GloFAS provided that they meet the following requirements:
- Temporal coverage: from 01-01-1970 to real time
- Number of data: 365 daily data. The time series does not have to be continuous, that is the 365 daily data can be distributed over multiple years.
- Upstream drainage area: 50 km2.
- Licence: we collect hydrological in-situ data available as open-source data.
- Station metadata:
- River basin
- River name
- Station name
- Coordinates: latitude and longitude (preferred in WGS84)
- Drainage area (km2)
- Discharge units
- Timezone of discharge measurements
- Height above mean sea level
The minimum drainage area for which GloFAS simulations provide reliable results depends on the spatial resolution of the latest operational version: please refer to the GloFAS versioning system wiki page for all the details about the latest and the upcoming GloFAS releases.
