Parameters:
input=name[,name,...] [required]
Names of ASTER DN layers (15 layers)

dayofyear=float [required]
Day of Year of satellite overpass [0-366]

sun_elevation=float [required]
Sun elevation angle (degrees, < 90.0)

output=name [required]
Base name of the output layers (will add .x)

DESCRIPTION


i.aster.toar calculates the Top Of Atmosphere (TOA) reflectance for Terra-Aster L1B in the
visible, NIR and SWIR bands (9+1 bands) and brigthness temperature for the TIR bands (5
bands), all from L1B DN values. It is useful after importing your Aster imagery from
storage format that is generally in standard DN values range.

The order of input bands is

· VNIR: 1,2,3N,3B

· SWIR: 4,5,6,7,8,9

· TIR: 10,11,12,13,14
in one comma-separated list.

NOTES


Internally, a gain code is defined to modify gains according to spectral bands following
the GeoSystems GmbH ATCOR Ver. 2.0 Calibration Files. The function is defined in
gain_aster.c file.
/*Gain Code*/
/*0 - High (Not Applicable for band 10-14: TIR)*/
/*1 - Normal*/
/*2 - Low 1(Not Applicable for band 10-14: TIR)*/
/*3 - Low 2(Not Applicable for Band 1-3N/B and 10-14)*/
