Climate change: Daily maximum temperature projections, daily data, RCP4.5 scenario, resolution 0.125°

The database contains a time series of daily climate projections of the daily maximum air temperature in the period 1981-2100 for the greenhouse gas emissions scenario RCP4.5 above Slovenia in the correct grid resolution of 0.125°. For scenario RCP4.5, simulations of six regional climate models are available. The simulations are the result of regional models of the EURO-CORDEX project. Their resolution is 0.11°. Data are corrected for measurements in Slovenia in the period 1981-2010 (the so-called bias correction). More about the EURO-CORDEX project can be found in the additional links. The data is in NetCDF files, which are divided into 30-year periods due to their size. There are four files available for each model. Each 30-year period is marked with the year of the last year of the period. Model projection files have names containing data on variable name, models, projection time, version, etc., separated by underscores. The components of the names are: variable name (tasmax: daily maximum air temperature), model resolution (12km: 0.125°), the name of the global climate model that gave marginal conditions to the regional, abbreviation of the greenhouse gas emissions scenario (rcp45: RCP4.5), ensemble parameters (e.g. r1i1p1), name of regional climate model, projection version, projection time step (day: 1 day) and the start and end dates of the projection (in the format YYYYMMDD, where YYYY is the year, MM is the month and DD is the day). The model results represent the physically possible states of the climate system in the future according to the day marginal condition, which in this case is the course of the concentration of greenhouse gases. Greenhouse gas concentrations cannot be predicted, so in its fifth report of 2014, the International Panel on Climate Change (IPCC) produced four plausible scenarios for it, given the socio-economic development of humanity in the future. Since the model results differ from each other, and each of them represents a possible state of the climate, their results need to be statistically processed. The differences between them provide the basis for assessing the uncertainty of the projections. A summary of the analyses of climate change up to the end of the century in Slovenia can be found among the additional links. There is also the first synthesis report on climate change in Slovenia, which contains a more detailed description of the methodology and results of climate projections. Chapter 1 on climate projections, Chapter 3.2 on regional climate models and Chapter 4.3 on the correction of model errors and biases. One of the options for working with NetCDF files (extraction, aggregation, etc.) is the CDO program. Reading and statistical processing on NetCDF files is also possible with the R statistical package, especially with its ncdf4 and raster packages. You can find links to CDO and R programs in additional links.
