These data were produced to support the article "Forecast-based attribution of a winter heatwave within the limit of predictability" (see citation and link to paper elsewhere on this record). Within the archived products the directory tree structure is as follows: Top level domain splitting: >EU Model data at 0.25 degree resolution for the region contained within (33 to 73.5N / -27 to 45E). >GLOB Model data at 0.25 degree resolution for the full globe. Below which there are sub-directories as follows (note, M-climate is only available for the EU domain): >>ENS​ Data from the operational Ensemble Prediction System (EPS) forecast. >>M-climate Data from EPS hindcasts used to construct model climate. See https://confluence.ecmwf.int/display/FUG/M-climate%2C+the+ENS+Model+Climate. >>pi-CO2 Data from EPS forecast that replicates operations *but for* reduced CO2 concentrations, set to 285 ppm. >>incr-CO2 Data from EPS forecast that replicates operations *but for* increased CO2 concentrations, set to 600 ppm. Within these runs the data are then available on the following level types: >>>pl Data on pressure levels. >>>sfc Data on single levels. Ensemble data are further split into sub-directories as follows: >>>>cf Control forecast member. >>>>pf Perturbed forecast members. The specific variables available within each netCDF file can differ depending on the region and experiment type (eg. the operational ENS forecasts whose initialisation dates match those of the perturbed CO2 experiments have more variables available than the others). All the datasets & variables required to reproduce the analysis are described in the paper. Forecast-based attribution of a winter heatwave within the limit of predictability. Nicholas J.

Data are either operational forecast data, or experiments that use an identical model version and setup to operations in which the CO2 concentration has been perturbed. These experiments would replicate operations but for the CO2 perturbations. Data were post-processed using cdo1.9.8 and NCO4.7.2. The data were then sent to the Centre for Environmental Data Analysis (CEDA) for archiving.
