title: RoCliB - Bias corrected CORDEX RCM dataset over Romania

description: This dataset contains a set of four climate variables from 10 General Circulation Models (GCMs), dynamically downscaled in the EURO-CORDEX initiative by several Regional Climate Models (RCMs) and adjusted (bias-corrected) over Romania for the period 1971–2100. The climate models data were obtained from the EURO-CORDEX archive. Two climate change scenarios were selected, namely the moderate (RCP4.5) and business-as-usual scenario (RCP8.5). The multivariate bias correction by the N-dimensional probability density method (MBCn) was used to bias correct the RCMs outputs [1], using as reference the ROCADA gridded dataset [2]. Characteristic: <strong>Climate variables</strong>: air temperature (tasAdjust - Celsius degree), maximum air temperature (tasmaxAdjust - Celsius degree), minimum air temperature (tasminAdjust - Celsius degree) and precipitation (prAdjust - mm). <strong>Temporal resolution:</strong> daily <strong>Temporal extent</strong>: Historical: 1971-2005; RCP4.5 and RCP8.5: 2006-2100. <strong>Spatial resolution:</strong> 0.1 degrees (~10km) <strong>Spatial extent:</strong> from 20.1 to 29.8°E and 43.5 to 48.4°N. <strong>File format: n</strong>etCDF, CF-1.4-compliant format using netCDF4 compression. <strong>Coordinate system: </strong>WGS 1984 (EPSG:4326) <strong>Naming conventions: </strong><em>variablename</em>_ROU-11_<em>cmip5experiment</em>_<em>globalmodel</em>_<em>run</em>_r<em>egionalmodel</em>_<em>rcmversionid</em>_<em>timefrequency</em>_<em>starttime-endtime</em><em>.</em>nc <strong>RMCs</strong> (Institution or working group, RCM Model, GCM Institute, GCM Driving): Climate Limited-area Modelling Community (CLMcom) CCLM4-8-17 CNRM-CERFACSCNRM-CM5 Royal Netherlands Meteorological Institute (KNMI) RACMO22E CNRM-CERFACS CNRM-CM5 Swedish Meteorological and Hydrological Institute (SMHI) RCA4CNRM-CERFACS CNRM-CM5 Climate Limited-area Modelling Community (CLMcom) CCLM4-8-17 ICHECEC-EARTH Swedish Meteorological and Hydrological Institute (SMHI) RCA4I CHECEC-EARTH Royal Netherlands Meteorological Institute (KNMI) RACMO22E ICHECEC-EARTH Danish Meteorological Institute (DMI) HIRHAM5 ICHECEC-EARTH Climate Limited-area Modelling Community (CLMcom) CCLM4-8-17 MPI-MMPI-ESM-LR Swedish Meteorological and Hydrological Institute (SMHI) RCA4 MPI-MMPI-ESM-LR Climate Service Center Germany (GERICS) REMO2015 NCC NorESM1-M <strong>Acknowledgement</strong><br> This work was supported by a grant from the Romanian National Authority for Scientific Research and Innovation, CCCDI-UEFISCDI, project number COFUND-SUSCROP-SUSCAP-2, within PNCDI III.
