[GRASS-user] i.atcorr whit Aster Data - null value - WARNING: Unknown atmospheric model!....

[Gabriele N.]

 Hi,
I have a problem with i.atcorr with data aster.  I tried it with grass 64
and 7, on ubuntu 15.04 64-bit.

Maybe I'm wrong to set the parameters of the txt? (Is there anyone can tell
me if they are correct? I have attached the file .met)...Otherwise I do not
know.....

/10                           - geometrical conditions=ASTER
01 16 15.28 -74.9 -14.8      - month day hh.ddd longitude latitude ("hh.ddd"
is in GMT decimal hours)
2                            - atmospheric mode=midlatitude summer
1                            - aerosols model=continental 
15                           - visibility [km] (aerosol model concentration)
-0.121                       - mean target elevation above sea level [km]
-1000                        - sensor on board a satellite
72                           - aster band 1 (0.480-0.645) /

 
The result I get is always with null values.

In the output window:
/
wavelength  less  than  0.25  micron: 
 let's take s(l)=s(0.25)
WARNING: Unknown atmospheric model!
WARNING: Unknown aerosol model!/

Only in some cases there is a warning wavelength.

Here there is the file .met
AST_L1B_00301162001152851_20150713051848_23493.met

I've seen other threads such as Yann but I did not understand the problem

Thank you
