rrtmg_libraries

This project consists of two libraries:

• rrtmg_input_erai_lib for convenient way to read data from ERA Interim reanalysis, standard profiles and CERES dataset,
• rrtmg_lib to make input files for Rapid Radiative Transfer Model for GCM use (RRTMG).

Additionally, there are executable files of RRTMG (built for use on some Linux machines); examples of data and examples of use. If the executable files of RRTMG don't work, see the instruction of compilation here: http://rtweb.aer.com/rrtm_frame.html
