GloFAS river discharge forecast (deterministic)
Daily river discharge forecast up to 30 days from GloFAS v4 (Global Flood Awareness System, Copernicus / ECMWF) served via Open-Meteo. Returns m3/s per day at the grid cell nearest to the supplied coordinates. Optional percentile bands and retrospective past_days lookback to 92 days. Data by Open-Meteo.com, CC BY 4.0.
Query parameters
Latitude in decimal degrees (-90 to 90). Provide latitude+longitude OR river.
Latitude in decimal degrees (-90 to 90). Provide latitude+longitude OR river.
Longitude in decimal degrees (-180 to 180). Provide latitude+longitude OR river.
Longitude in decimal degrees (-180 to 180). Provide latitude+longitude OR river.
River name as an alternative to latitude+longitude. Curated rivers resolve to a validated GloFAS-mainstem cell; others fall back to the geocoder.
