How are these lists made?

Each region is read at one reference place using 30 years of ERA5-Land climate. For every crop, our season model (the one the AgriAuditor field audit uses) finds the month its sowing window opens there. We checked it against eight state extension planting calendars: 93% of crops fell within a month of the published window.
