Long-term Changes in Extreme Air Pollution Meteorology and the Implications for Air Quality
Extreme air pollution meteorological events, such as heat waves, temperature inversions and atmospheric stagnation episodes, can significantly affect air quality. Based on observational data, we have analyzed the long-term evolution of extreme air pollution meteorology on the global scale and their potential impacts on air quality, especially the high pollution episodes. We have identified sign...
متن کاملMulti-pollutant surface objective analyses and mapping of air quality health index over North America
Air quality, like weather, can affect everyone, but responses differ depending on the sensitivity and health condition of a given individual. To help protect exposed populations, many countries have put in place real-time air quality nowcasting and forecasting capabilities. We present in this paper an optimal combination of air quality measurements and model outputs and show that it leads to si...
متن کاملپیشبینی شاخص کیفیت هوا برمبنای متغیرهای هواشناسی و مولفههای خودهمبسته با استفاده از شبکه عصبی مصنوعی
Background: Air Quality Index (AQI) quantifies the relationship between air quality and the level of health. The value of AQI may be predicted using neural network model for a day in advance, based on the meteorological variables and autocorrelation behavior of the index in Kermanshah, a city in western Iran. Methods: Data for air pollution and meteorological variables, collected during thre...
متن کاملDetermination of the Distribution of NO2, CO, and PM2.5 Concentration Using a Photochemical Model of Air Pollution: Case Study of Tehran City
Background and objectives: Tehran is one of the most polluted cities in the world in terms of air pollution. Modeling is a useful tool in air pollution management. The objectives of this study are to determine the distribution of the main air pollutants concentration in Tehran and to construct a photochemical model appropriate to the geography and natural characteristics of Tehran. Methods: I...
متن کاملStatus of CO as an air pollutant and its prediction, using meteorological parameters in Esfahan, Iran
The present study analyzes air quality for Carbon monoxide (CO), in Esfahan with the measurements taken in three different locations to prepare average data in the city. The average concentrations have been measured every 24 hours, every month and every season with the results showing that the highest concentration of CO occurs generally in the morning and at the beginning of night, while the l...
