Data for "An Ensemble-Based Statistical Methodology to Detect Differences in Weather and Climate Model Executables"

Ensemble simulations from the weather and climate model COSMO. The data has been used for model verification cases in the corresponding paper.

The data is partitioned into two parts:

10d_gpu_cpu_sp_diff.tar:
10-day ensembles produced with COSMO 5.09:
- GPU version using double precision (gpu_dycore)
- CPU version using double precision (cpu_nodycore)
- GPU version using single precision (gpu_dycore_sp)
- GPU version using double precision and a tiny amount of additional explicit diffusion (gpu_dycore_diff)

10d_update.tar:
10-day ensembles produced with COSMO 5.05 before and after a major system update of the underlying supercomputer Piz Daint:
- GPU version before update (before_update)
- GPU version after update (after_update)

Each folder in the respective .tar files contains 100 or 50 ensemble members (stored as NetCDF file) that have been produced with the corresponding executable/configuration.
