Palmerindeksen
Palmerindeksen, also known as the Palmer Drought Severity Index (PDSI), is a measure of drought severity that combines precipitation, temperature, and other climatic factors to assess the impact of drought on water resources. Developed by Wayne Palmer in 1965, the PDSI is widely used in climatology and hydrology to monitor and predict drought conditions.
The index is calculated using a water balance model that takes into account the difference between precipitation
The Palmerindeksen is particularly useful for its ability to provide a historical perspective on drought conditions,
