Hi,
I am using the flaash program to do atmospheric correction in level 1b modis data. As far as it reaches 11%, I get an ACC error message: ktaerosol:determine blue/red test usage. How can I solve this problem? Any help would be appreciable!
Thanks in advance

I don't recognize the error you mention. Can you post the full error message and template you used? What version of ENVI are you running? It is probably best to go to Technical Support directly with this question.

I am using ENVI 5.0!
The exactly error is:
Problem: The FLAASH programeixted with the following errors:
ACC error: ktaerosol:deterimine blue/red test usage
IDL error:
Variable is undefined:REFCUT
ACC_KTAEROSOL
ACC_HYPER2
ACC_ACC
ENVI_ACC_EVENT
ENVI_FLAASH_PROCESS_MANAGER

I still do not recognize the error. If you turn off aerosol retrieval, does the process continue? The error seems to be with aerosol correction. Can you post the template?

No, that's my problem! I have tried it and I still get the same error!
I don't have the permition to upload any file.. The input image for flaash is radiance (bands 20-36) which I have converted to BIL.
I have thought that maybe the error is because the other bands are missing, but I don't know how to input them all together.

MODIS bands 20-36 are mid to thermal bands and are not appropriate for FLAASH. FLAASH is intended to process visible and SWIR bands ranging from 400-2500nm.

Thanks for the answer! I tried it (this time the inputs were 1-19 bands+26 band) but I get the same error...so I suppose something else is going wrong!!
