Data for "An Ensemble-Based Statistical Methodology to Detect Differences in Weather and Climate Model Executables"
收藏资源简介:
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:<br> 10-day ensembles produced with COSMO 5.09:<br> - GPU version using double precision (gpu_dycore)<br> - CPU version using double precision (cpu_nodycore)<br> - GPU version using single precision (gpu_dycore_sp)<br> - GPU version using double precision and a tiny amount of additional explicit diffusion (gpu_dycore_diff)<br> 10d_update.tar:<br> 10-day ensembles produced with COSMO 5.05 before and after a major system update of the underlying supercomputer Piz Daint:<br> - GPU version before update (before_update)<br> - 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.
