500-member ensemble simulation output from NIES Chemistry-Climate Models for investigating total ozone dependence on ODS and GHG consentrations

Click Here to Download Click Here to Download

The archived data is outputs from chemistry-climate models (CCSRNIES-MIROC3.2 CCM and CCSRNIES-MIROC5 CCM) that were run with 25 pairings of fixed GHG (greenhouse gases) and ODS (ozone depleting substances) concentrations for the future. The model calculations are 510 years' continuous runs with a pair of fixed ODS and GHG concentrations and the outputs from the last 500 years are stored as a 500-member ensemble.

Calculation method
Chemistry-climate models (CCSRNIES-MIROC3.2 CCM and CCSRNIES-MIROC5 CCM) were run with GHG (greenhouse gases) and ODS (ozone depleting substances) concentrations at the surface fixed to the values for the future. The model calculations are 510 years' continuous runs. Sea surface temperature and sea ice area were given by the output from an atompshere-ocean coupled general circulation model (GCM) that was run on the RCP6.0 scenario for the future years, corresponding to the year of the GHG concentrations of each experiment.The model resolution was 2.8° x 2.8° (T42) in horizontal and 1-3 km in vertical.
How to use
  • See the top directory named as "500-ens_fODSGHG_ver.1.0".
  • Under the directory, there are two directories "MIROC3.2" and "MIROC5". The output from these models are stored under these directories.
  • The file name "···fGHGxxxx_fODSyyyy···.tar.bz2" indicates a run in which GHG (CO2, CH4, and N2O) and ODS concentrations are fixed to the values on the RCP6.0 scenario and the WMO-A1 scenario for the future. When the "···.tar.bz2" files are decomposed, the direcrtories of the same name without "tar.bz2" are produced. Subordinate 500 directories from "y2011_1/" to "2510_1/" contain five binary files in gtool format for one year; the files of total ozone data named as "dobson_ver.1.0" ([DU], 2-dimendial data in longitude-latitude), those of zonal wind speed data named as "U_50hPa_ver.1.0" ([m/s], 2-dimentional data in longitude-latitude at 50 hPa), those of temperature data named as "T_50hPa_ver.1.0" ([K], 2-dimimentional data in longitude-latitude at 50hPa), those of inorganic chlorine data named as "qcly_50hPa_ver.1.0" ([volume mixing ratio], 2-dimimentional data in longitude-latitude at 50hPa), and those of inorganic bromine data named as "qbry_50hPa_ver.1.0"([volume mixing ratio], 2-dimimentional data in longitude-latitude at 50hPa). Gtool is a data analysis and visualization tool for geophysical science developed by GFD Dennou Club. The version "gtool3.5" was used for data processing. Note that the binary data are stored in the big endian.
  • The information of the model coordinates is found in the files "GTAXLOC.GLON128" (longitiutde information in the gtool format) or "GTAXLOC.GLON128.txt" (a file with text-style format read from "GTAXLOC.GLON128") and "GTAXLOC.GGLA64" (latitude information in the gtool format) or "GTAXLOC.GGLA64.txt" (a file with text-style format read from "GTAXLOC.GGLA64") in the top directory.
  • An example of Fortran code to read the 2-dimientional files in the gtool format ("dobson", "T_50hPa", "U_50hPa", "qcly_50hPa", and "qbry_50hPa") is provided in the top directory as "read_2d_t42.f".
