Service Description:

A special index has been developed for Hungarian conditions. The Pálfai Drought index (PAI) is named as 'drought index', however it rather characterises the dryness of the year or a longer period according to a classification, uniformly applied for the whole country:

PAI = 100∙(TIV-VIII/PX-VIII)∙ kt∙kp∙kgw

TIV-VIII: average temperature between April and August [oC], PX-VIII: sum of precipitation between October and August [mm], kt, kp, kgw: coefficients depending on number of days with heat, on number of days without precipitation and on shallow groundwater level during spring, respectively. All data correspond to the period 1991-2020.

PAI values for HydroSHEDS_12 are spatial averages of the corresponding grid values of the PAI maps.
