Ag-Weather API
Access agriculture-focused weather and land-surface data from the ERA5 reanalysis, and satellite/radar based precipitation datasets with consistent global coverage at 9 KM resolution.
Browse forecast and historical ag-weather endpoints with agriculture-specific weather and land-surface variables.
- Covers agriculture-specific weather fields.
- Includes historical and forecast use cases.
- Supports crop, soil, and field operations planning.
Frequently Asked Questions
How is reference evapotranspiration calculated?
Our API uses an updated Penman-Monteith calculation based on the FAO56 methodology, with improvements that better estimate ET0 in hot and humid conditions.
