Online WOFOST is a fast way to run WOFOST for regions in the world where wheat, maize and soy bean are dominantly cropped using (as much as possible) local relevant data.
Hands-on experience of WOFOST is possible via WOFOST-online. It is a fast way to run WOFOST for regions in the world where wheat, maize and soy bean are dominantly cropped using (as much as possible) local relevant data.

Input is taken from the following global data sets:
- Weather: ECWMF-ERA5, aggregated to daily timesteps and adapted to finer topography, finer land use pattern and finer land-sea delineation of the ECMWF operational model at 0.1 degree grid.
- Soil: WISE30SEC version 1.0 (Batjes, 2015)
- Crop: start and phenological related TSUM parameters based on regional GAEZ calendars
- Crop delineation: based on the Global Food Security Support Analysis Data (GFSAD) Crop Dominance 2010 Global 1 km
- Model: crop parametrisation as default WOFOST files
- Results are given for two yield levels: potential (Yp) and water-limited (Yw). More information can be found on the Global yield gap atlas website
- Crop data has limited local relevance as it has been derived from regional calendars. Next release will include the possibilty to enter a location specific planting date and crop cycle length
- Winter wheat simulation starts at the moment of “regrowth” (in spring).
- The initialization of soil water, relevant for the water-limited simulation, starts halfway between field capacity and wilting point and runs 1 month before emergence.
- The cumulated rainfall includes rainfall from the start of the initialization, thus 1 month before emergence.
