SYNOPSIS


i.albedo
i.albedo --help
i.albedo [-mnlacd] input=name[,name,...] output=name [--overwrite] [--help] [--verbose]
[--quiet] [--ui]

Flags:
-m
MODIS (7 input bands:1,2,3,4,5,6,7)

-n
NOAA AVHRR (2 input bands:1,2)

-l
Landsat 5+7 (6 input bands:1,2,3,4,5,7)

-a
ASTER (6 input bands:1,3,5,6,8,9)

-c
Aggressive mode (Landsat)
Albedo dry run to calculate some water to beach/sand/desert stretching, a kind of
simple atmospheric correction

-d
Soft mode (MODIS)
Albedo dry run to calculate some water to beach/sand/desert stretching, a kind of
simple atmospheric correction

--overwrite

--verbose
Verbose module output

--quiet
Quiet module output

--ui
Force launching GUI dialog

Parameters:
input=name[,name,...] [required]
Name of input raster map

output=name [required]
Name for output raster map

DESCRIPTION


i.albedo calculates the albedo, that is the Shortwave surface reflectance in the range of
0.3-3 micro-meters. It takes as input individual bands of surface reflectance originating
from MODIS, AVHRR, Landsat or Aster satellite sensors and calculates the albedo for those.
This is a precursor to r.sun and any energy-balance processing.

NOTES


It assumes MODIS product surface reflectance in [0;10000].

TODO


Maybe change input requirement of MODIS to [0.0-1.0]?
