PBL wind speed observations compared to model values. The (a, c) WINTER and (b, d) SUMMER model wind speed errors for the SLUCM_MYJ (first row) and BEP_BouLac (second row) configurations. Positive values indicate an overestimate in the model. Points are binned every 50 m and each point has a minimum of 10 unique data points that are used to create an average error for that binned height and time of day. The comparisons were done for grid points that were designated as an NLCD 2006 urban cover land cover type. DOI: https://doi.org/10.1525/elementa.132.f10
