Calculation of ITH index

Description

ITH index calculation is made from gridded observational or model data. If the data is needed in lat/lon projection is better to use first the load.by.variable function to change projection

The index is calculated as:

ITH = 1.8 * T(ºC) + 32 - (((0.55 - (0.55 * RelHum(\%))) / 100) * ((1.8 * T(ºC)) - 26))

where T(ªC) is the temperature in celsius degrees and RelHum(%) is the relative humidity in percentage

Usage

ith(raster.list = raster.list)

Arguments

raster.list

Spat Raster variable with several variables and times or only one Spat Raster field

Value

Spat Raster with ITH calculation for each time
