This function calculates the danger levels (VeryLow-Low-Moderate-High-VeryHigh-Extreme) for a given country.
get_fire_danger_levels(fire_index, ndays = 4)
fire_index |
RasterBrick containing the fire index to calculate the thresholds for. Please note that fire_index@z should contain dates. |
ndays |
Number of days per year in which a fire is expected to occur. By default this is 4 days. |
A numeric vector listing the thresholds.
