Type of Update: Bug Fix Release Version/Date: CMAQv5.4
Description:
Dry deposition velocities used to be computed in MCIP, then read by CMAQ. The capability to compute deposition velocities online (or "inline") was added in CMAQv4.7 in December 2008. The computation of deposition velocities was later removed from MCIP. However, the CMAQ code still had ILDEPV as a commented-out flag in DEPV_DEFN, as well as the RDDEPV routine, which was never called. These remnants have all been removed.
Significance and Impact: Removes non-working option that had the potential for confusing users.
