介绍了WRF-CMAQ耦合气象-空气质量模式系统中陆面模式(LSM)和行星边界层(PBL)部分的研究进展。这些修改的目的主要是改进对夜间过渡期间和夜间氮氧化物(NOx)、一氧化碳(CO)、颗粒物(PM)和臭氧(O3)等痕量化学物种地面浓度的模拟。然而，对气象和空气质量量的评估表明，添加到PX LSM和ACM2 PBL方案中的先进算法在白天和晚上都改善了结果。在不同网格间距(1、4和12公里)以及不同年份和季节的模拟实验都显示出显著的改进。这些组件的修订版已经在WRFv3.7中发布，并将于2015年秋季在CMAQv5.1中发布。
Advances in the land surface model (LSM) and planetary boundary layer (PBL) components of the WRF-CMAQ coupled meteorology and air quality modeling system are described. The aim of these modifications was primarily to improve the modeling of ground level concentrations of trace chemical species such as nitrogen oxides (NOx), carbon monoxide (CO), particulate matter (PM), and ozone (O3) during the evening transition and overnight. However, evaluation of both meteorological and air quality quantities shows that the advanced algorithms added to the PX LSM and the ACM2 PBL schemes improved results both day and night. Modeling experiments at various grid spacings (1, 4, and 12 km) and for different years and seasons all show significant improvements. The revised versions of these components have already been released in WRFv3.7 and will be released in the fall of 2015 in CMAQv5.1.
