  • This experiment uses the data from the WRF60_eraint_ctrl experiment as forcing data for downscaling to 12km resolution by the regional model, WRFV3.5.1 for the region of West Africa. The 'control'-run is a reanalysis of observed data similar to an experiment of the CMIP5 - Coupled Model Intercomparison Project Phase 5 (https://pcmdi.llnl.gov/mips/cmip5). This experiment is divided into several time slices of 11 years. The first year of each time slice is used as a spin-up phase and should not be used in the analysis. The 12 km resolution of this experiment is the second step of the two step downscaling WRF experiment.

  • This experiment uses 'CMIP5 ECMWF-ERAINT reanalysis data' as forcing data for downscaling to 60km resolution by the regional model WRFV3.5.1 for the region of West Africa. The 'control'-run is a reanalysis of observed data similar to an experiment of the CMIP5 - Coupled Model Intercomparison Project Phase 5 (https://pcmdi.llnl.gov/mips/cmip5). This experiment is divided into several time slices of 11 years. The first year of each time slice is used as a spin-up phase and should not be used in the analysis. The 60 km resolution of this experiment is an intermediate step to the 12km downscaling WRF experiment.

  • The data represent monthly average values of pre-industrial climate simulation. Here, for the year 1860, concentrations of well mixed greenhouse gases (CO2, CH4, N2O) were prescribed. Ocean data (MPI-OM) are available within this experiment, they are stored in EXTRA FORMAT. Datasets with higher resolution (6 hour mean) are also available. As the boundary conditions are not time dependent, the time access is arbitrary. Technical data to this experiment: The experiment is using ECHAM5.2.02 coupled to MPI-OM Vers.1.0 GR1.5L40 and was run on a NEC-SX6(hurrikan). The output from the model run: hurrikan.dkrz.de:/ut/3/m214002/EXP500/run520

  • The data represent monthly avarage values of a simulation, initialized in the same year as experimnet 20C_1, with an annual CO2 increase of 1% until doubling in 1930. Between 1931 and 2080 the CO2 concentration was held constant. All other concentrations remain at their preindustrial levels (nominally year 1860). Data with higher resolution (6 hourly) are also available. Technical data to this experiment: The experiment is using ECHAM5.2.02a coupeld to MPI-OM Vers. 1.0 GR1.5L40 The output from the model run: hurrikan.dkrz.de:/ut/m/m214002/EXP500/run522

  • The purpose of the project DEKLIM-EEM is to reconstruct past interglacials based on proxy data and to understand the processes that are responsible for climatic changes during these interglacials by applying climate models. The data represent monthly average value of a simulation of the preindustrial climate (PRI) at around 1800 yr AD. Boundary conditions are equivalent to the other simulations of the project, apart from the concentration of greenhouse gases and orbital parameters: Greenhouse gas concentrations are derived from vostok ice core data: 280 ppmV CO2, 0.70 ppmV CH4 and 265 ppbV N2O. CFCs are set to zero. Orbital parameters have been calculated with the routine of Berger (1978): Eccentricity: 0.0167; Obliquity: 23.44; Perihelion: 282.7 The simulation has been started with the Levitus ocean climatology. ECHO-G is used as climate model. It is a coupled atmosphere/ocean model (ECHAM4_T30 + HOPE-E_T42er). The simulation was run on a NEC-SX6 (hurrikan). Atmospheric data were originally stored by the model every 12 hours. Ocean data is stored every month. As the boundary conditions are not time dependent, the time access is arbitrary. Related experiments: - ECHOG_A16_LIG control run, last interglacial (Eemian, 125 kyrBP, DEKLIM-EEM project), started with Levitus climatology, monthly mean values - ECHOG_A40_LGI: control run, last glacial inception (End of the Eemian, 115 kyrBP, DEKLIM-EEM project), started with Levitus climatology, monthly mean values.
