Hi all, I'm new to ENVI programming, but, not new programming in general. I'm trying to estimate net radiation using Landsat 7 data, and I'm programming this in ENVI/IDL. I have found several ENVI routines that will help me out with this task. However, I think there is still much more that I need to do. I was wondering if anyone already had a program to estimate net radiation, or could tell me if there was an easy way to program this issue.
