RoCliB - Bias corrected CORDEX RCM dataset over Romania

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:

• Climate variables: air temperature (tasAdjust - Celsius degree), maximum air temperature (tasmaxAdjust - Celsius degree), minimum air temperature (tasminAdjust - Celsius degree) and precipitation (prAdjust - mm)
• Bias-correction method: multivariate bias correction (N-pdft)
• The reference period used for bias correction: 1971-2005
• The observational dataset used as a reference for bias correction: ROCADAv1
• Temporal resolution: daily
• Temporal extent: 
  • Historical: 1971-2005;
  • RCP4.5 and RCP8.5: 2006-2100.
• Spatial resolution: 0.1 degrees (~10km)
• Spatial extent: from 20.1 to  29.8°E and 43.5 to 48.4°N
