TM5-MP global chemistry transport model version 1.2

This is the source code of the chemistry-transport model TM5-MP model developed and run for the simulations presented in the  manuscript: "Description and Evaluation of a Secondary Organic Aerosol and New Particle Formation Scheme within TM5-MP v1.2" authored by T. Bergman et al. currently under review by journal Geoscientific Model Development. This version includes the changes in order to run extra simulation described in the paper. The version controlled TM5-MP repository can be found at http://www.gitlab.com/tm5-ctm after requesting access from philippe.le.sager@knmi.nl.
