LMDz prescribed concentrations (LMDZ / prescrconcs)

Description

This plugin reads LMDz prescribed concentrations

Example of use for CH4 chemical sinks on a 96 x 96 horizontal grid with 39 pressure levels with a 1 day time resolution:

The concentrations field variable must have the same name as the corresponding species.
