Maps and graphs

Here are shown relevant maps and graphs for essential climate variables (CVs) and indicators that can be used for climate change analysis in Romania. The maps can be downloaded as PNG file, and the raster data used to compute the maps can be downloaded for each visualised variable in GeoTIFF format.

The climate variables' (CVs) changes are computed for each season and at the annual scale as differences between future periods (2021-2050 and 2071-2100) and the historical period (1971-2000). The changes are computed as absolute (°C) for air temperature and relative (%) for precipitation.

The climate indices changes are computed at the annual scale as differences between future periods (2021-2050 and 2071-2100) and the historical period (1971-2000). The changes are computed as relative (%) for precipitation and as absolute ( Σ°C, number of days) for the rest of the indices.

The climate variables and indicators are aggregated at the NUTS2 (Regions), NUTS3 (Counties) and LAU (Local administrative units) (see Romania administrative units ).

About

Built in R using Shiny , this dashboard aims to provide accurate and relevant facts and statistics about climate change in Romania. The application is based on ensemble means computed from 10 adjusted (bias-corrected) RCMs data, which are provided via the Zenodo open-access repository (RoCliB). The data are archived in a netCDF CF-1.4-compliant format using netCDF4 compression. For each variable and scenario distinct files were created: 4 climate variables × (10 Historical + 10 RCP8.5 + 10 RCP4.5) = 120 netCDF files. The terms of use for the bias-corrected data are the same as those from the original EURO-CORDEX simulations obtained from ESGF servers .

The main characteristics of the RoCliB dataset are listed below:
  • Climate variables: air temperature (tasAdjust - Celsius degree), maximum air temperature (tasmaxAdjust - Celsius degree), minimum air temperature (tasminAdjust - Celsius degree) and precipitation (prAdjust - millimeters);

  • 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;

  • File format: netCDF, CF-1.4-compliant format using netCDF4 compression;

  • Coordinate system: WGS 1984 (EPSG:4326);
