International Transport of Ozone and Precursors (ITOP-UK): Atmospheric Chemical Measurements and Analyses

Study of intercontinental transport of air pollutants by means of coordinated flights over the East coast of North America, the Azores and the West coast of Europe. ITOP was a component of the International Consortium for Atmospheric Research on Transport and Transformation (ICARTT), an international initiative which coordinates the efforts of various American and European groups who have developed plans for field campaigns in the summer of 2004, with the aim of improving our understanding of the factors determining air quality over the two continents and over remote regions of the North Atlantic. The British contribution to ITOP, referred to as ITOP-UK, was funded by the Natural Environment Research Council (NERC) through the Upper Troposphere Lower Stratosphere (UTLS)-Ozone Directed Research Programme.

The ITOP-UK dataset includes trajectories and other forecast products calculated by John Methven (University of Reading), based on European Centre for Medium-Range Weather Forecasts (ECMWF) forecast wind fields, to support ICARTT flight planning, near-real-time chemical analyses produced by the University of Cambridge, and data collected aboard the FAAM Bae-146 aircraft in July and August 2004.

本项研究通过协调飞行途径对北美东海岸、亚速尔群岛及欧洲西海岸的空气污染物跨洲传输进行探究。ITOP项目作为国际大气传输与转化研究合作组织（ICARTT）的组成部分，该组织是一项国际性倡议，旨在协调美国与欧洲各研究团体在2004年夏季进行的现场观测活动计划，旨在提升我们对决定两大洲及北大西洋偏远地区空气质量的决定性因素的认知。英国对ITOP的贡献，即ITOP-UK项目，由自然环境研究委员会（NERC）通过上层对流层下层平流层-臭氧定向研究计划（UTLS-Ozone Directed Research Programme）提供资金支持。ITOP-UK数据集包括由雷丁大学约翰·梅斯文（John Methven）计算得出的轨迹及其他预报产品，这些产品基于欧洲中期天气预报中心（ECMWF）的预报风场，以支持ICARTT的飞行规划；由剑桥大学生产的近似实时化学分析数据；以及2004年7月和8月在FAAM Bae-146飞机上收集的数据。
