The School of Earth and Environment installed an Omniglobe device in the reception foyer in 2015. It arrived with many pre-set scenarios mainly from NASA ( Early work by the atmospheric composition group placed TOMCAT simulations in a “University of Leeds” folder.

In 2017 CEMAC was asked to prepare animations from another atmospheric composition simulation (CESM-WACCM) of distribution of surface ozone. This video is 83MB reproduced close to “FullHD” (i.e. 1920×960 pixels). It is mp4 format although the images are stored as a sequence of PNG files when uploaded to the OmniGlobe, their resolution is set to 3000×1500 pixels.

A third animation was generated from data from a “nested” simulation using the Met. Office Unified model (local area modelling). Here is a PNG snapshot:

In the above image you can see condensed water path as a red concentration for the global model. The higher resolution local area model (LAM) it is indicated with a blue to green scale. Here is the animation (~30MB)

The process uses the Python “matplotlib” tools to extract 2-dimensional data from NetCDF formatted results files. A challenge is that the field files have different data structures. There is enough meta-data in the NetCDF file to decipher the content there seems to be no standard naming convention to create a generic tool to be used for all climate simulations. A separate python script was used for each application up to the point of plotting where the scripts become common.
