evaluateDroughtNemaAithumidity: Evaluates Drought Conditions Relating to Air Humidity Based...

Description Usage Arguments Value Examples

Description

evaluateDroughtNemaAithumidity evaluates based on relative air humidity values for a target time period as raster based time series (RasterBrick or RasterStack object, if for a given spatial and temporal point drought or near drought conditions are prevalent or not (according to the classification of the NEMA). This function considers only the additional criteria related to the relative air humidity.

Usage

1
evaluateDroughtNemaAithumidity(airhumidity, airhumidity_t)

Arguments

airhumidity

A RasterBrick or RasterStack object with mean relative air humidity values on a daily basis within the target time period.

airhumidity_t

A POSIXct vector containing the time information for all layers in airhumidity as returned by dailyMeans (each element denoting the respective day).

Value

A list with two elements:

droughtairhumidity

A RasterBrick object containing for each fixed ten-day interval in airhumidity_t a layer classifying if there were drought conditions according to the relative air humidity or not.

time

A character vector specifying the date of the first day of the respective fixed ten-day interval.
