QGIS algorithm - i.evapo.pm

Description

QGIS Algorithm provided by GRASS i.evapo.pm (grass:i.evapo.pm). Computes potential evapotranspiration calculation with hourly Penman-Monteith.

Usage

grass_i_evapo_pm(
  elevation = qgisprocess:::qgis_default_value(),
  temperature = qgisprocess:::qgis_default_value(),
  relativehumidity = qgisprocess:::qgis_default_value(),
  windspeed = qgisprocess:::qgis_default_value(),
  netradiation = qgisprocess:::qgis_default_value(),
  cropheight = qgisprocess:::qgis_default_value(),
  .z = qgisprocess:::qgis_default_value(),
  .n = qgisprocess:::qgis_default_value(),
  output = qgisprocess:::qgis_default_value(),
  GRASS_REGION_PARAMETER = qgisprocess:::qgis_default_value(),
  GRASS_REGION_CELLSIZE_PARAMETER = qgisprocess:::qgis_default_value(),
  GRASS_RASTER_FORMAT_OPT = qgisprocess:::qgis_default_value(),
  GRASS_RASTER_FORMAT_META = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

elevation	raster - Name of input elevation raster map (m a.s.l.). Path to a raster layer.
temperature	raster - Name of input temperature raster map (C). Path to a raster layer.
relativehumidity	raster - Name of input relative humidity raster map (%). Path to a raster layer.
windspeed	raster - Name of input wind speed raster map (m/s). Path to a raster layer.
netradiation	raster - Name of input net solar radiation raster map (MJ/m2/h). Path to a raster layer.
cropheight	raster - Name of input crop height raster map (m). Path to a raster layer.
.z	boolean - Set negative ETa to zero. 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. Original algorithm parameter name: -z.
.n	boolean - Use Night-time. 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. Original algorithm parameter name: -n.
output	rasterDestination - Evapotranspiration. Path for new raster layer.
GRASS_REGION_PARAMETER	extent - GRASS GIS region extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used..
GRASS_REGION_CELLSIZE_PARAMETER	number - GRASS GIS region cellsize (leave 0 for 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.
GRASS_RASTER_FORMAT_OPT	string - Output Rasters format options (createopt). 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.
GRASS_RASTER_FORMAT_META	string - Output Rasters format metadata options (metaopt). 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.
...	further parameters passed to qgisprocess::qgis_run_algorithm()
.complete_output	logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
.quiet	logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
.messages	logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
