Atmosphere-Ocean Chemistry Experiment Phase II: Meteorology of Transport and Deposition over the North Atlantic

AEROCE是一个以北大西洋地区为中心的多学科大气和海洋化学研究计划。该计划的目标包括通过观察臭氧、化学示踪剂和其他物质来了解北大西洋的化学气候学；估计北美燃烧的硫和氮的出口；以及了解大气沉积对化学循环的影响。该项目的主要目标是了解气象因素在观测到的化学可变性中的作用。P.I.将准备和分析众多气象产品，包括来自四个AEROCE站的时空等熵空气质量轨迹，来自附近官方观测站的无线电探空上升分析，以及来自邻近站和源区站的常规气象报告的汇编和分析，将把这些气象结果与化学观测综合起来，计算和分析每个站点的主要输送路径及其季节变化。

AEROCE is a multi-disciplinary atmospheric and marine chemistry research program centered in the North Atlantic region. The program objectives include understanding the chemical climatology over the North Atlantic Ocean using observations of ozone, chemical tracers and other substances; estimating the export of combustion sulfur and nitrogen from North America; and understanding the impact of atmospheric deposition on chemical cycles. The primary objective of this project is to understand the role of meteorological factors in the observed chemical variability. The P.I. will prepare and analyze numerous meteorological products, including isentropic air mass trajectories back in time from the four AEROCE stations, analysis of radiosonde ascents from nearby official observing stations, and compilations and analyses of routine meteorological reports from adjacent stations and stations in source areas, will synthesize these meteorological results with the chemical observations, calculating and analyzing the main transport paths and their seasonal variation for each site.
