Examination of the effect of evapotranspiration as an output parameter in SPEI drought index in Central Bohemian region

We examined the effects of two different parameterisations of potential evapotranspiration (ET) in calculating water balance as an outup parameter into SPEI drought index. The first parameterisation is derived from daily precipi...
