RD1SD: EMAC CCMI-2022 hindcast simulations with specified dynamics, ERA-5, 1979-2019

This experiment comprises one specified dynamics hind-cast simulation (1979-2019) with EMAC at T42L90MA resolution under the CCMI-2022 refD1 protocol, see

SPARC, 2021: SPARC Newsletter No. 57, July 2021, 39 pp., available at http://www.aparc-climate.org/publications/newsletter .

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 specified dynamics has been achieved by nudging (Newtonian relaxation) of EMAC towards ECMWF ERA-5 reanalysis data.

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.
