Code to post-process CESM-CAM/WACCM transformed Eulerian mean output to useful circulation diagnostics (e.g., v*, w*). Based on code from Isla Simpson.
The code follows the 'TEM recipe' from Appendix A of Gerber, E. P. and Manzini, E.: The Dynamics and Variability Model Intercomparison Project (DynVarMIP) for CMIP6: assessing the stratosphere–troposphere system, Geosci. Model Dev., 9, 3413–3425, https://doi.org/10.5194/gmd-9-3413-2016, 2016 and the corrigendum.
