The Kingdom of Saudi Arabia has initiated a program to install air quality network stations throughout the country in order to measure concentration of the ambient air pollutants. The site selection of these stations is an important objective to be accomplished and must be done based on scientific and rational work. To accomplish this objective, a modified version of atmospheric transport and dispersion model, known as air resources laboratories - atmospheric transport and dispersion (ARL- ATAD) model, is used to evaluate long range transport and diffusion of air pollutants from major pollution causing sources such as refineries, open-air burning of associated gases of oil fields and major industries. Hourly meteorological data for a period of three years (from 1977 to 1979) on wind speed, wind direction, pressure, and temperature from 20 synoptic stations in Saudi Arabia is processed and used as model input. In addition to these, meteorological data from three upper air stations is also processed in order to determine base and top of critical inversion heights. Various pollution causing sources are identified within the study area. Air trajectories are drawn with sources as the origins of the trajectories and the dispersion characteristics is studied with distance and time. Based on long term meteorological records, the adversely affected zones are statistically identified for potential station sites.
沙特阿拉伯王国已启动一项计划，在全国安装空气质量监测站网络，以测量环境空气污染物的浓度。这些监测站的选址是一项必须基于科学合理工作完成的重要目标。为实现这一目标，一种经过改进的大气传输与扩散模型，即空气资源实验室 - 大气传输与扩散（ARL - ATAD）模型，被用于评估来自炼油厂、油田伴生气露天燃烧和主要工业等主要污染源的空气污染物的长距离传输和扩散。对沙特阿拉伯20个天气站三年（1977年至1979年）期间每小时的风速、风向、气压和温度气象数据进行处理，并用作模型输入。除此之外，还对三个高空站的气象数据进行处理，以确定临界逆温层高度的底部和顶部。在研究区域内识别出各种污染源。以污染源为轨迹起点绘制空气轨迹，并研究其随距离和时间的扩散特征。基于长期气象记录，从统计角度确定潜在监测站选址的受不利影响区域。
