Description
Abstract: The data set contains daily time-step observed and scenario climate data on a European grid with 25 km x 25 km spatial resolution and is intended to be used for crop modelling applications. The dataset covers the period 1980-2010 for observations (for a baseline period of 1981-2010 and the year 1980 for crop model simulations with sowing dates in the autumn) and the periods 2040-2069 and 2070-2099 for 5 GCMs x 2 forcing scenarios (RCP4.5 and RCP8.5) and 2 GCMs with RCP2.6. The Joint Research Centre’s (JRC) Agri4Cast gridded dataset was used for the baseline. The scenarios have been calculated using an enhanced delta change method that applies changes in aspects of temperature and precipitation variability in addition to changes in mean climate.

Methods: The structure of the single tables refers to the gridcode of the model, for example the gridcode 35120 fits the location 35_120. This means the gridcode column is 120, the row 35. The explanation can be found in the properties of the kml file or the associated grid file.

SeriesInformation: Two versions of the dataset are available: version 1 (this page - DOI: https://www.doi.org/10.4228/ZALF.DK.59; consisting of 8709 grid cells) that was used by Webber et al. (2018) and an updated version 2 (DOI: https://www.doi.org/10.4228/ZALF.DK.94; consisting of 8748 grid cells) that corrects an error when accounting for altitude differences to agricultural cultivation areas. It is recommended to use the latest version, unless the data are intended to be used for direct comparison with the results of Webber et al. (2018) https://www.doi.org/10.1038/s41467-018-06525-2.

Additional info
Data are stored as comma-separated values (csv) in one file per grid cell containing values for the baseline and all scenarios. Gridcell IDs are composed of the column and row numbers (see image below). Download is possible for individual grid cells or tar-packages containing files for a range of column numbers (i.e. defining a longitudinal band). Please send to us name of your square name from Geolocation. One single package contains one csv file (see above - Structure of Data Table).
THe dataset consist of 8.709 dowloadable packages. Each package contain one single csv file with name of column + name of row. See image below.
