software for implementing a 2-stream solution

The two-stream package is build on three executables, written with the C and Fortran90 languages. They are all based on the same low-level radiation transfer routines as in [Pinty et al., 2005] but differ in their scope:

1. The 2stream executable is written with the C language and is built as a command-line tool which proposes a user interface with flags and options, thoroughly checks input parameters and eventually prints out the calculated fluxes. It gives access to the intermediate calculation steps (the separated radiation components) as in [Pinty et al., 2005].

It is designed as a demonstration/educational tool or as a processing tool to be included in scripts.

2. The Simple2stream and Simple2streamF executables are written with the C and Fortran90 languages, respectively. They are much simpler in the way the programs are written but are much less convenient to use.

They are designed to help and guide those users who would want to integrate this two-stream formulation in bigger codes (e.g. GCM) in C or Fortran.

Download the two-stream package from http://fapar.jrc.it/WWW/Data/Pages/FAPAR_Software/FAPAR_Software_RTModels_two-stream.php

The following zip file contains the source code (in C and Fortran) for the two-stream model.
Documentation on how to install and use the package can be found in files README, INSTALL and EXAMPLES, once the archive is unzipped.
Users are requested to read this documentation and to contact the authors (see below) if some information is missing or unclear.
