    The data represent 6 hours values of selected variables for the Data Distribution Centre (DDC) of the Intergovermental Panel on Climate Change (IPCC). (see also: http://ipcc-ddc.cru.uea.ac.uk) The B1 scenario describes a storyline with rapid change in economic structures toward a service and information economy, with reductions in material intensity and the introduction of clean and resource-efficient technologies. The experiment has been initialized in year 2000 of the 20C_3 run and continues until year 2100 with anthropogenic forcings (CO2, CH4, N2O, CFCs, O3 and sulfate) according to B1. The experiment is extended until year 2200 with all concentrations fixed at their levels of year 2100 (stabilization experiment). Datasets with monthly average values are also available. Technical data to this experiment: The experiment is using ECHAM5.2.02a coupled to MPI-OM Vers. 1.0 GR1.5L40 and was run on a NEC-SX (hurrikan). The output from the model run: hurrikan.dkrz.de: /ut/k/k204097/EXP000/run011

    The CLAAS-2 record provides cloud properties derived from the SEVIRI sensor onboard METEOSAT second generation (MSG) satellites. This second edition is the improved and extended follow-up of the first version of the record (Stengel et al., 2014; CLAAS-1 DOI:10.5676/EUM_SAF_CM/CLAAS/V001). In order to ensure a homogeneous data basis, the solar SEVIRI channels of MSG-1, MSG-2 and MSG-3 were intercalibrated (Meirink et al, 2013) with MODIS Aqua before applying the cloud retrievals. CLAAS-2 features 12 years (2004-2015) of cloud mask/type, cloud top temperature/pressure/height, cloud phase as well as cloud microphysical properties such as optical thickness, effective droplet radius and cloud water path. The data are available on native SEVIRI resolution, i.e. 15 minutes repeat cycle and 3km (nadir) to 11km (edge of the field of view) spatial resolution. In addition, spatio-temporal averages of the above mentioned cloud properties are included: Daily and monthly averages and monthly histograms on a 0.05° x 0.05° grid as well as monthly mean diurnal cycles on a 0.25° x 0.25° grid. The advancements compared to CLAAS-1 (DOI:10.5676/EUM_SAF_CM/CLAAS/V001) are for example: (1) extended MSG measurement record used with better calibration, (2) improvements made to the retrieval algorithm leading to products with higher quality and (3) increased temporal resolution (15 Minutes). A summary on the CLAAS-2 characteristics and a comprehensive evaluation of the results are currently documented in Benas et al. (2016). Along with the data, a comprehensive documentation including user guide, algorithm descriptions, reprocessing layout and extensive validation studies, is provided. With CLAAS-2, regional and large scale cloud processes at temporal scales of minutes to years can be studied. SEVIRI-based surface radiation products, which were part of CLAAS-1, are now released in a separate dataset (SARAH-2). This is a Thematic Climate Data Record (TCDR).

    The data represent 6 hourly values of a simulation, initialized in the same year as experimnet 20C_3, 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 monthly average values 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/k/k204076/EXP000/run008
