Drought

Palmer Drought Severity Index (PDSI) (Hogg, E.H., Price, D.T., McKenney, D.W.)

The PDSI is calculated using precipitation, temperature, moisture-holding capacity of the soil, and local infiltration. Positive values represent wetter conditions, while negative values represent drier conditions, compared to the long-term (30-year) historical average for a location.
