NAME
i.eb.evapfr - Computes evaporative fraction (Bastiaanssen, 1995) and root zone soil
moisture (Makin, Molden and Bastiaanssen, 2001).
KEYWORDS
imagery, energy balance, soil moisture, evaporative fraction, SEBAL
SYNOPSIS
i.eb.evapfr
i.eb.evapfr --help
i.eb.evapfr [-m] netradiation=name soilheatflux=name sensibleheatflux=name
evaporativefraction=name [soilmoisture=name] [--overwrite] [--help] [--verbose]
[--quiet] [--ui]
Flags:
-m
Root zone soil moisture output (Makin, Molden and Bastiaanssen, 2001)
--overwrite
Allow output files to overwrite existing files
--help
Print usage summary
--verbose
Verbose module output
--quiet
Quiet module output
--ui
Force launching GUI dialog
Parameters:
netradiation=name [required]
Name of Net Radiation raster map [W/m2]
soilheatflux=name [required]
Name of soil heat flux raster map [W/m2]
sensibleheatflux=name [required]
Name of sensible heat flux raster map [W/m2]
evaporativefraction=name [required]
Name for output evaporative fraction raster map
soilmoisture=name
Name for output root zone soil moisture raster map
DESCRIPTION
i.eb.evapfr calculates the evaporative fraction after [1]. Main implementation in [3]. It
takes input of Net Radiation (see r.sun, i.eb.netrad), soil heat flux (see
i.eb.soilheatflux) and sensible heat flux (see i.eb.hsebal01). A flag adds a root zone
empirical soil moisture output from the article of Makin, Molden and Bastiaanssen (2001).
