Arguments

TAVG

multilayer - Mean Temperature. .

TMIN

multilayer - Minimum Temperature. .

TMAX

multilayer - Maximum Temperature. .

PSUM

multilayer - Precipitation. .

SNOW

rasterDestination - Snow Depth. Path for new raster layer.

SW_0

rasterDestination - Soil Water (Upper Layer). Path for new raster layer.

SW_1

rasterDestination - Soil Water (Lower Layer). Path for new raster layer.

LAT_GRID

raster - Latitude. Path to a raster layer.

LAT_CONST

number - Default Latitude. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

SWC

raster - Soil Water Capacity of Profile. Path to a raster layer.

SWC_DEFAULT

number - Default. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

SWC_SURFACE

number - Top Soil Water Capacity. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

SWT_RESIST

number - Transpiration Resistance. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

RESET

boolean - Reset. 1 for true/yes. 0 for false/no. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

DAY

string - Start Day. String value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
