## Abstract

A recently published meteorology and air quality
modeling study has several serious deficiencies deserving comment.
The study uses the weather research and forecasting/chemistry
(WRF/Chem) model to compare and evaluate boundary layer and land
surface modeling options.  The most serious of the study's
deficiencies is reporting WRF/Chem results for both meteorological
and chemical quantities using the asymmetric convective model
version 2 (ACM2).  While the ACM2 is a valid model option for WRF,
it has not yet been implemented for the chemical portion of the
WRF/Chem model.  Hence, the reported air quality modeling results
using ACM2 are invalid.  Furthermore, publication of these results
gives the erroneous impression that the ACM2 model is not well
suited for air quality applications when, in fact, it is the
default boundary layer model in the community multiscale air
quality (CMAQ) model.
