Average daytime model PBL heights for WINTER. The WINTER average daytime PBL heights for (a, b)SLUCM_MYJ, (c, d)SLUCM_MYNN, (e, f)BEP_MYJ, (g, h)BEP_BouLac, and (i) none_MYNN simulations using default urban fractions (left column) and the updated urban fraction values (right column). The (i) none_MYNN simulation does not use the urban fraction parameter; therefore, there is no updated urban fraction none_MYNN simulation. DOI: https://doi.org/10.1525/elementa.132.f11
