VALUE Datasets

Available datasets: 

Description: To enable a fair comparison that reveals relative strengths and weaknesses of different methods, the selected validation data for Experiment 1a has been defined considering 86 locations in Europe spanning different climatic regions. Further experiments will also consider gridded data (compliant with the EURO-CORDEX grids). To keep the exercise as open as possible, the data is restricted to publicly available datsets either on the VALUE website itself, or –after registration– on the web-page of the respective weather service. More details on the observational and gridded datasets are given in the links below:

The following datasets are ASCII files containing daily information [description of data format]:

  1. ECA&D local observations recipitation and temperatures (mean, minimum and maximum) for 86 locations in Europe representative of the different climatic and orographic gradients.
    * (17/4/2015)VALUE_ECA_86_v2.zip

    This dataset is used for Experiment 1a. Previous versions and detailed 
    information of the changes (outliers and inconsistencies) are available in the  observational station data page. See the Info.txt file in the datset for further details.
    NEW (23/12/2015): VALUE_ECA_12_Germany_multivar_v2.zip
    Subset of VALUE_ECA_86 including twelve stations in Germany with daily data for precipitation, temperatures, daily mean wind speed, daily maximum wind speed, relative humidity, and cloud cover. This dataset is used for the multi-variable case study of Experiment 1a. 
    NEW (23/12/2015)VALUE_ECA_53_Germany_spatial_v1.zip
    Set of 53 stations from ECA in Germany with daily data for precipitation and temperatures. This dataset is used for the spatial validation case study of Experiment 1a.  
  2. ERA-Interim (0.75º) gridded data for the gridboxed closes to the local stations. These datasets are provided to facilitate the contribution of bias correction methods to the VALUE Experiments. It contains daily time series from ERA-Interim reanalysis of the same varaibles included in the corresponding ECA datasets at the (0.75º) gridboxes closest to the target stations.: 
    * (27/11/2015): VALUE_ERA_INTERIM075_86_v2.zip
    NEW (03/02/2016): VALUE_ERA_INTERIM075_12_Germany_multivar_v1.zip
    NEW (03/02/2016): 
    VALUE_ERA_INTERIM075_53_Germany_spatial_v1.zip
  3. E-OBS gridded observations for the (0.22º) gridboxes closest to the 86 locations. This dataset contains daily time series for precipitation, minimum, mean and maximum temperatures and is used for Experiment 1b. See the Info.txt file in the datset for further details.
    * (31/8/2015): VALUE_EOBS_86_v2.zip
  4. KNMI-RACMO (0.11º) gridded ERAInterim-driven simulations for the gridboxes closest to the 86 locationsThis dataset is provided to facilitate the contribution of bias correction methods to the VALUE experiments. It contains daily time series for precipitation, minimum, mean and maximum temperatures at the gridboxes closest to the target stations.  See the Info.txt file in the datset for further details.
    * (31/8/2015): VALUE_RACMO011_86_v2.zip

The following dataset are NetCDF files:

  1. Observational gridded datasets for precipitation and temperature used in Experiment 1b (national-wide and European-wide). Details here.
  2. ERA-Interim (daily means at 2º). A standard pre-selection of commonly used predictors is available from the User Data Gateway (UDG) of the  Santander MetGroup (this dataset is used by the statistical downscaling portal). Registration (and acceptance of the ECMWF data policy) is required. Subsets of this dataset can be 1) downloaded in a user-friendly form using a web browser or 2) remotely accessed from R (more information here; also in pdf). The same predictors from several CMIP5 Earth System Models will be also available for succeeding experiments.
