There are a number of manuals to support scientists working with this code, including:
Nemesis_3.0.pdf This is the main NEMESIS manual. As
explained in the About NEMESIS page, much of the NEMESIS
model builds upon the pre-existing RADTRAN code.
NEMESIS4Newbies.pdf The NEMESIS and RADTRAN manuals
are somewhat dense and detailed. Hence, new users may wish to look at this document to better understand
how to use the software.
