Historical and simulated yields of spring wheat at different spatial scales for each selected sites.
CAR (ECD): official yields at the Census Agricultural Region (Ecodistrict) scale from Statistics Canada’s Field Crop Reporting Series. RM: official yield at rural municipality scale. APSIM: simulated yields using APSIM (station-based weather data used for the simulations). There is no historical yield data available at RM scale for Lacombe. The discontinuity periods in field-scale yield data are reported in Table 2.
