The files are consistent with CMAQv5.5 CRACMM2, but data can be used in CMAQv5.4 and later and all versions of CRACMM with appropriate adjustments. Data include emissions, meteorology, fertilizer information, lightning information, model initial chemical conditions, and surface information for the domain.
