Palmer Drought Severity Index (PDSI) and (PHDI) calculation and mapping using Rstudio
In this video you will learn about how you can calculate palmer Drought Severity Index (PDSI) and Map
-PDSI -is a drought indicator
-used drought indicator to quantify the long-term drought conditions, for an area at a certain time.
-calculated using the precipitation (P) and potential evapotranspiration data (PE)
1. P = Monthly precipitation series without NA [mm]
calculated from daily precipitation using prcenticon package
2. PE = Monthly potential evapotranspiration
Can be calculated by the Penman-Monteith or the Thonthwate equation [mm]. from temperature average (Tavg)
PDSI data = a combination of P & PE
pdsi(P, PE, AWC = 100, start = NULL, sc = TRUE)
