Restore Vertical Diffusion and Gravitational Settling Diagnostic Files#
Chris Nolte , U.S. Environmental Protection Agency
Type of update: Bug Fix
Release Version/Date: CMAQv5.5
Description: The environment variable VDIFF_DIAG_FILE is supposed to control whether the CCTM outputs the vertical diffusion diagnostic file CTM_VDIFF_DIAG, and if gravitational settling is being used, additionally the CTM_VSED_DIAG file. However, there was a bug that prevented these diagnostic files from being written even if the user requested these outputs in the run script.
Significance and Impact: No change to model calculation. Allows for outputting vertical diffusion and gravitational settling diagnostic files.
