Evaluating WRF-GC v2.0 predictions of boundary layer height and vertical ozone profile during the 2021 TRACER-AQ campaign in Houston, Texas by X. Liu, Y. Wang, S. Wasti, W. Li, E. Soleimanian, J. Flynn, T. Griggs, S. Alvarez, J. T. Sullivan, M. Roots, L. Twigg, G. Gronoff, T. Berkoff, P. Walter, M. Estes, J. W. Hair, T. Shingler, A. J. Scarino, M. Fenn, L. Judd

“…Compared with the airborne HSRL-2, the model exhibits a moderate to strong spatial correlation (<span class="inline-formula"><i>R</i>=0.26</span>–0.68), with <span class="inline-formula">±20</span> % biases during the noon and afternoon hours during ozone episodes. For land–water differences in PBL heights, the water has shallower PBL heights compared to land. …”
