Forecasting the green-up day-of-year (DOY) was simulated for each year by successively adding greenness observations to the mean greenness curve and calculating the mean absolute error (MAE) within each natural sub-region. The natural sub-regions shown represent 24% of the wildfire protection area and the green-up DOY was forecasted to be more than 10 days from the actual green-up DOY by March 22 (DOY 81).
