Historic Agricultural Drought Frequency (Global - 1 Km - ASIS)

Historic Agricultural Drought Frequency Maps depict the frequency of severe drought in areas where 30 percent/50 percent of the cropland/grassland has been affected. The historical frequency of severe droughts (as defined by ASI) is based on the entire ASI times series (1984-2021).

Formula: The number of years when land affected>30 percent/50 percent occurred/(2021-1984+1) *100

Pixel value ranges from 0-100 (unit: percentage). Flag: 252: no data; 253: no season; 254: no cropland/grassland.
