Adequacy_P95 = Seasonal_AETI / P95(Seasonal_AETI within crop class). Measures the relative water consumption compared to the top 5% performing water-consuming areas of the same crop under local conditions.

Usage

wapor_calc_adequacy_p95(aeti_seasonal, crop_mask, p95_table)

Arguments

aeti_seasonal

SpatRaster. Seasonal AETI raster.

crop_mask

SpatRaster. Crop mask.

p95_table

data.frame. Output from wapor_calc_p95_aeti().

Value

A SpatRaster of P95-based adequacy.
