这项工作研究了巴塞罗那（西班牙）地区空气污染物的循环模式，该地区受沿海和地形影响很大。这是通过利用弹性反向散射激光雷达数据和利用气象中尺度模型 (MEMO) 对大气进行数值模拟来实现的。激光雷达数据是在 1992 年 7 月洛斯阿拉莫斯国家实验室 (LANL) 和加泰罗尼亚理工大学 (UPC) 之间的合作活动中获取的。激光雷达提供有关气溶胶分布和盛行风的信息，这些信息是通过对弹性反向散射激光雷达数据应用最大互相关算法来确定的。激光雷达风用于评估模型模拟的高空风。这项研究表明，巴塞罗那的环流模式与白天对流垂直混合、海风环流以及山脉热力和机械效应引起的垂直强迫相关。
This work examines circulatory patterns of airpollutants in the area of Barcelona (Spain), a regionwith strong coastal and orographic influences. Thiswas achieved through exploitation ofelastic-backscatter lidar data and by numericalsimulation of the atmosphere with a meteorologicalmesoscale model (MEMO). Lidar data were acquired inJuly 1992 during a collaborative campaign between LosAlamos National Laboratory (LANL) and the PolytechnicUniversity of Catalonia (UPC). The lidar providedinformation about the distribution of aerosols and theprevailing winds, determined by application of amaximum cross-correlation algorithm toelastic-backscatter lidar data. Lidar winds are usedto evaluate high altitude winds simulated by themodel. This study showed that circulatory patterns inBarcelona are correlated with daytime convectivevertical mixing, sea-breeze circulations, and verticalforcing caused by mountain thermal and mechanicaleffects.
