Summary of Results and Issues emanating from tests with EOBS19

Overall timing is very favourable compared to CLIMPACT2, here is a summary extracted from the slurm log:

  1. A identified before (#129 (closed)) the spell based calculations (cdd and cwd) are comparatively much slower. By monitoring the progress, the step INFO:root:Setting up aggregation was identified as the time consuming part. Suggestion is to update the logging to facilitate this (#143 (closed))

  2. For some indices (i.e. cdd, cwd, txx, txn, tnx, tnn, tmn, tmx) it appears that masking is not correctly implemented or the mask is not correctly implemented in the input file (#144 (closed)). Cf. excerpt from the slurm log:

INFO:root:saving empty cube
/home/sm_lbarr/.conda/envs/climix-devel-3/lib/python3.7/site-packages/iris/fileformats/netcdf.py:2038: UserWarning: Cube 'air_temperature' contains unmasked data points equal to the fill-value, 1e+20. As saved, 
these points will read back as missing data. To save these as normal values, please specify a 'fill_value' keyword not equal to any valid data points.
  warnings.warn(msg.format(cube.name(), fill_value))
INFO:root:opening
INFO:root:Starting with DimCoord([1950-07-02 12:00:00], bounds=[[1950-01-01 00:00:00, 1951-01-01 00:00:00]], standard_name='time', calendar='gregorian', long_name='time', var_name='time')
  1. Preliminary comparisons with the reference data (produced by CLIMPACT2) indicate that there are some differences, but this is complicated by the masked data are included.
