Hi Shouvik,

What is the exact error which you are getting while performing the 6S RTM Corrections on L8?

Alternatively, do you know that you can directly find Surface Reflectance (SR) products of Landsat 8 from the USGS? The SR products are already corrected radiometrically and atmospherically. The algorithm used for L8 correction was developed by NASA Goddard (GSFC) which is called the L8SR. Landsat 4, 5 and 7 SR products are also available for download which is corrected using the 6S model algorithm. However, the L8 SR products are provisional, when I last checked in September 2015. Not sure what is the status right now. In any case go through the pdf which I have attached.

Shouvik,

The 2 papers and 1 set of slides linked to below deal with atmospheric corrections but are not ENVI related, however, I thought you you might be interested in seeing them.

 Hi Shouvik Jha

did You manege to run 6s in Envi? Can you help me on that?
