In the case of air quality studies Yerramilli et al. (2010, 2012) showed that the surface ozone simulations produced byWRF/Chem model were influenced by the PBL parameterization schemes and that the k-theory based first-order YSU scheme produced better results than the ACM2 and MYJ schemes for simulating the diurnal cycle and ozone mixing ratios in the Mississippi Gulf coastal region.
