Description
evaluateDroughtNema1 evaluates
for a target time period, if
for a given spatial and temporal point drought or near drought conditions are
prevalent or not (according to the main criteria classification of the NEMA).
Usage
1
2
evaluateDroughtNema1(droughttemperaturemain, droughttemperatureadditional,
droughtprecipitation, droughtairhumidity, timedate)
Arguments
droughttemperaturemain
A RasterBrick object a returned by
evaluateDroughtNemaTemperatureMain containing the classification
if the temepratures of respective ten-day intervals for a pixel result in
drought conditions or near-drought conditions (according to the meain criteria).
droughttemperatureadditional
A RasterBrick object a returned by
evaluateDroughtNemaTemperatureAdditional containing the classification
if the temepratures of respective ten-day intervals for a pixel result in
drought conditions (according to the additional criteria).
droughtprecipitation
A RasterBrick object a returned by
evaluateDroughtNemaPrecipitation containing the classification
if the precipitation of respective ten-day intervals for a pixel result in
drought conditions or near-drought conditions.
droughtairhumidity
A RasterBrick object a returned by
evaluateDroughtNemaAirhumidity containing the classification
if the relative air humidity of respective ten-day intervals for a pixel result in
drought conditions.
timedate
A POSIXct vector containing the time information
for all layers of the input raster objects.
Value
A list with two elements:
droughtA RasterBrick object containing for each
fixed ten-day interval a layer classifying if there were
drought conditions or near-drought conditions according to all criteria or not.
timeA character vector specifying the date of the first day of the
respective fixed ten-day interval.
