| description:
|
The Palmer drought index (PDI) is a measurement of dryness based on recent precipitation and temperature and is based on a supply-and-demand model of soil moisture. The index has proven most effective in determining long-term drought, a matter of several months, but it is not as good with conditions over a matter of weeks. It uses a 0 as normal, and drought is shown in terms of negative numbers; for example, negative 2 is moderate drought, negative 3 is severe drought, and negative 4 is extreme drought. Palmer's algorithm also is used to describe wet spells, using corresponding positive numbers.The Moisture Anomaly Index (PDI-Z) is an estimate of the moisture difference from normal (a 30-year mean). It compares conditions for the current month against the long-term average. For more information, visit: https://open.canada.ca/data/en/dataset/35b4153e-593f-47aa-91c0-c2f706382079 |
