This experiment comprises one free-running hind-cast simulation (1950-2019) 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 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.

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.

This experiment comprises 4 different simulations: - hind-cast simulations, free-running - SSTs/SICs: global data set HadISST provided by the UK Met Office Hadley Centre - model data output mostly as 10-hourly global snapshots, monthly averages or as monthly accumulated variables, on model levels or pressure levels, respectively RC1-base-07: T42L90MA 1960–2011 RC1-base-07a: same as RC1-base-07, with corrected optical properties of stratospheric aerosol 1990-2010 RC1-base-08: T42L47MA 1960-2011 RC1-base-08a: same as RC1-base-08, with corrected optical properties of stratospheric aerosol 1990-2010 For further studies based on simulations of the ESCiMo project and on the EMAC model please also refer to: https://www.atmos-chem-phys.net/special_issue812.html https://gmd.copernicus.org/articles/special_issue10_22.html https://www.atmos-chem-phys.net/special_issue22.html http://www.pa.op.dlr.de/~PatrickJoeckel/ESCiMo/publications/escimo_publications.html Technical details: simulation run on IBM Power 6 p375 "Blizzard" at DKRZ

This directory (experiment) contains volcanic SO2 data derived from limb viewing satellites for the lower stratosphere from 1998 to 2012. The usage of the data is described in Timmreck et al., (2018), datasets VolcDB1 and VolcDB1_3D. We provide 3D-plumes of observed volume mixing ratio perturbations in the lower stratosphere / upper troposphere typically derived from 10-day periods as nc-files and integrated values of injected SO2 mass with peak latitudes and altitudes as Fortran formatted ascii files (A11,5(1X,I3),I4,4(1X,I3),5(1X,I2),I3,4(1X,I2)) for at maximum 5 events at one time. Instead of A11 I2,I5,I5 can be used to read in the components of time. The data from Dec. 1997 to Jan. 2002 are based on L2-files of SAGE II (V7.0) provided by the NASA DAAC (Thomason et al., 2008). The data from Jul. 2002 to Mar. 2012 use the updated 5-day time series of MIPAS (Hoepfner et al., 2015), supplemented by SO2 derived from GOMOS extinctions (Bingen et al., 2017, with a corresponding table). SO2volc3D_pap_T42L90r.nc: 3D SO2 for 131 events in T42L90 resolution (ECHAM-grid in grid_T42L90.nc) surface to about 80km).. SO2volc3D_pap_T63L90r.nc: same in T63L90 resolution (ECHAM-grid in grid_T63L90.nc). Here a downscaling by 0.7 for low latitude eruptions is recommended because of less removal by overshooting convection (The data in the T42 file and in the table in Bingen et al 2017 were upscaled within the measurement uncertainty to overcome the model artifact in low resolution, this applies only for the ENVISAT part from Jul. 2002 on). Latitude from South to North, for use with ECHAM please reverse. The levels on the hybrid-grid in the grid files are defined as lev(x,y,z)=hyam(z)+hybm(z)*apsave(x,y), in Pa (apsave annual average of surface pressure or orography). Volcano_or_region_echam_merged_dd_mm_yyyy.txt: integrated SO2 mass injected (in kt), SAGE and ENVISAT period. The postscript-file is an example on the T42 grid, the *doc-file includes the volcano names for the data in the *.txt Files, see also http://wwww.volcano.si.edu (Smithsonian volcano database). AEROCOM-DIEHL_UMZ1_tropo11.nc: Fluxes from outgassing volcanoes in the troposphere (below 200hPa), taken from AEROCOM (Diehl, 2012; Caution, filled with odd climatology after 2009, monthly, beginning in Jan. 1950) AEROCOM-DIEHL_1297-0312_tropo11.nc: Subset beginning Dec. 1997.
