Over the past 10-15 years atmospheric chemistry has evolved from a young research discipline devoted primarily to local problems of urban pollution and air quality to a mature science concerned with the hemispheric to global scale cycling of a wide variety of chemical species. To a large extent this change has resulted from an increasing realization that human activities can cause chemical disturbances to the natural troposphere on scales far beyond local concerns. Well-known examples include changes in the regional-to-global concentrations of certain nitrogen compounds, lead and other heavy metals, artificial radionuclides, a number of synthetic organic substances, certain acid-forming species, carbon dioxide and methane. These chemical changes in the atmosphere can often extend to the earth's soils, oceans, and biota far from the original source region. They can result in alterations in the earth's climate, changes in vital nutrient cycles, and impact significantly on the public health and quality of life on earth. The Atmosphere/Ocean Chemistry Experiment (AEROCE) will be a coordinated multi-institutional atmospheric and marine chemistry research project centered in the North Atlantic region. The ultimate goal of the AEROCE project will be the development of a predictive capability for the continentally derived species observed in the marine troposphere over the North Atlantic. The selection of sites and the measurement protocol in AEROCE has been developed jointly by modelers and field experimentalists. This project provides installation and operational support for AEROCE. A network of four aerosol, gas and precipitation sampling stations will be established in the North Atlantic Ocean at the following locations: Barbados, West Indies; Bermuda on the west end; Mace Head, Ireland, on the west coast; Tenerife, Canary Islands, at the obervatory at Izania at 2600 meters. Each station will have a three-pump aerosol filter sampling system and a triplet rain collector. The network will be completely operational by early 1988. During the first year all stations will collect aerosol and precipitation samples on a weekly basis, thereafter, on a daily basis. When the four station network is in full operation, it will yield about 6000 discrete filter and precipitation samples each year. The Secondary Network Operations Group will construct all equipment, install the stations on site, manage operations at the site through a local cooperative, and support and maintain the network stations. This group will also receive the samples and data from secondary network stations and redistribute the materials as required by AEROCE investigators.

在过去的10-15年里，大气化学从 一门年轻的研究学科，主要致力于研究当地的 城市污染和空气质量成为一门成熟的科学， 从半球到全球范围内各种化学物质循环 物种 在很大程度上，这种变化是由于 人们越来越认识到人类活动可能会导致化学物质 对自然对流层的扰动，其规模远远超过当地 性问题 众所周知的例子包括 某些含氮化合物、铅 和其他重金属，人工放射性核素，一些 合成有机物、某些酸形成物种、碳 二氧化碳和甲烷。 大气中的这些化学变化 经常延伸到地球的土壤，海洋和远离地球的生物群。 原始源极区域。 它们会导致 地球气候、重要营养循环的变化以及 对地球上的公众健康和生活质量有着重大的影响。 大气/海洋化学实验（AEROCE）将是 多机构协调大气和海洋化学 以北大西洋地区为中心的研究项目。 最终 AEROCE项目的目标是开发一个预测性的 对来自大陆物种的能力 北大西洋上空的海洋对流层。 的选址 AEROCE中的测量协议由 建模者和实地实验者。 该项目提供安装和操作支持， AEROCE。 四个气溶胶、气体和降水采样网络 将在北大西洋建立观测站， 以下地点：巴巴多斯，西印度群岛;百慕大群岛的伦敦西区; 梅斯黑德，爱尔兰，在西海岸;特内里费，加那利群岛，在 2600米处的Izania观测站 每个车站都有一个 三泵气溶胶过滤器采样系统和三重雨 收藏家 该网络将在年初完全投入使用 1988. 第一年，所有监测站都将收集气溶胶， 降水样本每周一次，此后，每天一次 基础 当四站网络全面运作时， 每个产生约6000个离散的过滤器和沉淀样品 年 二级网络运营组将构建所有 设备，在现场安装站，管理操作， 网站通过当地合作社，并支持和维护 网络站点。 该小组还将收到样本和数据 从二级网络站和重新分配的材料， AEROCE研究人员要求。
