The 'ECHAM5 (5.3.02)' files contain variables describing the physical / meteorological state of the atmosphere as simulated by the ECHAM5 General Circulation Model and the 'tr_Ox_HOx' files contain chemical species related to ozone. The Modular Earth Submodel System (MESSy - version is documented in the file header) is an integrated software framework for the assembly of Earth System Models (ESMs). MESSy is a multi-institutional project. "R" is short for "Ref" (=reference) according to the experiment protocols (in contrast to "S" for sensitivity). "C" and "D" denote the experiments of the first (CCMI-1) and second (CCMI-2022) project phase, respectively. Hind-cast simulations are labelled "1", and combined hind-cast and projection simulations are labelled "2". "SD" denotes "specified dynamics" simulations.
