Steps

  1. Call GET https://api.weather.gov/points/{lat},{lon} to resolve the WFO gridId and gridX/gridY for the field's coordinates
  2. Follow the returned .properties.forecastGridData link to pull the numeric gridpoint forecast (temperature time series)
  3. Derive daily GDD from the min/max temperature layers using your crop's base temperature and cap/floor rules
  4. Check the minimum temperature series against the crop's frost threshold to flag frost/freeze risk days
  5. Set a descriptive User-Agent header (app name + contact email) on every request
