Description:
A set of functions designed to calculate the standardised
precipitation and standardised precipitation evapotranspiration indices
using NASA POWER data as described in Blain et al. (2023)
. These indices are calculated using a reference
data source. The functions verify if the indices' estimates meet the
assumption of normality and how well NASA POWER estimates represent
real-world data. Indices are calculated in a routine mode. Potential
evapotranspiration amounts and the difference between rainfall and potential
evapotranspiration are also calculated. The functions adopt a basic time
scale that splits each month into four periods. Days 1 to 7, days 8 to 14,
days 15 to 21, and days 22 to 28, 29, 30, or 31, where 'TS=4' corresponds to
a 1-month length moving window (calculated 4 times per month) and 'TS=48'
corresponds to a 12-month length moving window (calculated 4 times per
month).
