Using a 30 km grid as a framework over Alaska, the number of drought polygons are intersected for each grid cell, in each drought category, for each time period. This information is then summarized for each time period using the following weighting scheme: (D0 * 1) + (D1 *2) + (D2 * 3) + (D3 * 4) + (D4 * 5). Higher values indicate higher drought intensity and duration. An external map service that depicts TCA (Terrestrial Condition Assessment) - Alaska Drought 2016 to 2019.
