Merge OCN

This page describes the work done to include the nitrogen cycle into ORCHIDEE. The nitrogen cycle was introduced into ORCHIDEE by Sonke Zaehle a few years ago. This version called O-CN was not parallelized and is now a bit obsolete, so it will be progressively merged into a copy of trunk of ORCHIDEE with regular updates (synchronization with the trunk). The release is expected for the end of 2013.

Preliminary work : add extra dimensions for some carbon variables (October 2012)

Work done by Didier : the following variables have now an extra dimension :

    turnover daily
    turnover_littercalc
    turnover_longterm
    biomass
    litter
    bm_to_litter
    bm_to_littercalc
    bm_sapl (parameter)
    bm_alloc
