A first meeting of various presentations around the tuning of models has been organised from 5 to 7 September 2017 within HIGH-TUNE at LMD (Paris).
The first day consists of presentations around the importance of tuning for climate models, the presentation of statistical tools that can be used for this tuning, the previous work on the comparison between single-column models and large-eddy simulations.
Afterwards, a coding sprint was organised in order to better understand the statistical tools developped by Daniel Williamson at the University of Exeter and start to apply them to the comparison of Single-Column models and Large-Eddy Simulations. For that, two case studies, one for the clear boundary layer and one for a fair-weather cumulus day.
