Update Nov 1, 2022: Please see additional code fix described in CAM github issue #678.
Topography file error
Title: Topography file error 2022
Issue: Regional refined topography was in the incorrect location/orientation
Model tags affected: NCAR_Topo_2_0_1 files for regional refinement. An erroneous topography file was specified for use when creating variable resolution grids between April 2022 and Jan 2023.
Model response: Gravity waves impacted, incorrect transport, chemistry fields displaced
Fix: Reprocess topography and re-run model simulations. If you created your own grid during that period please checkout the updated code at: https://GitHub.com/NCAR/Topoand recreate your topography file for your grid and re-run any simulations. To check if your topography file has this error, plot ANGLL vs ANGLX. In a "good" topo-file these variables should have large differences. In a "bad" file they will be very close everywhere.
