The results of satellite monitoring of pollution in the Russian sector of the Azov-Black Sea basin in 2003–2007 are considered. Within the framework of this work, a technology of monitoring the state and pollution of the water environment from satellite information received during this period from Russian and foreign satellites has been developed. With this technology, the coastal pollution parameters and hydrometeorological characteristics of the water environment in the area of observation were mapped operationally; 14 types of different satellite information products were issued daily; and the results were generalized over 3 days, ten days, a month, and a period of observation. Long-term satellite monitoring makes it possible to determine and analyze typical situations of pollution distribution in the coastal waters and to detect new circulation elements that transport pollutants, thus purifying the water environment. For example, for the first time, it was found from satellite data that the contribution of a small-scale circulation of waters of the Russian sector of the Black Sea to the transport and distribution of pollutants is commensurable with the contribution of the Main Black Sea Current and coastal anticyclonic eddies. The regularities in the dynamics of pollution distribution promote the increased reliability of charting of the environmental situation, including the prediction of dynamics of pollution spreading.  相似文献

This paper uses the dataset of Pollution Information Transparency Index covering 113 Chinese cities and the period of 2008–2011 to find out what contributes to different levels of environmental information disclosure across Chinese cities and the correlation between cities’ Pollution Information Transparency Indexes and local pollution. We find that cities whose mayors have longer tenures and PhD degrees are likely to release more environmental information. In addition, the higher the number of internet users and income per capita, the closer a city is to Hong Kong, and the lower a city’s unemployment rate, the greater the level of environmental disclosure is. An efficient local legal system is also found to facilitate information disclosure.We also find that in most cases, high Pollution Information Transparency Indexes are associated with lower pollutant levels and more pollution-control investment, suggesting the effectiveness of China’s environmental disclosure in pollution control. Community pressure for a better environment is shown to reinforce the role of environmental disclosure in pollution reduction. We find no evidence that environmental disclosure improves the efficacy of traditional environmental regulation in pollution control. Nevertheless, different aspects of environmental disclosure vary a lot in their effectiveness in pollution reduction and the results here indicate that inducing cities to respond to public information requests is perhaps the most effective method of pollution control in China.  相似文献

With the hourly data of Air Pollution Index (API) by Hong Kong Environmental Protection Department (HKEPD) during the 6 years of 2000 - 2005 and NCEP / NCAR reanalysis data of 2.5° × 2.5° wind and pressure fields, the characteristics of API in Hong Kong area and the impacts of typical weather characteristics on the air pollution in Hong Kong have been studied. The results are shown as follows. (1) The API exhibits obvious seasonal variability as the number of air pollution days increases by the year. For most of the local monitoring stations, it is the most from January to March, a little less from July to September and the least from April to June. (2) There are four typical types of weather situations that are responsible for the air pollution in Hong Kong: tropical cyclones, continental cold highs, transformed highs that have moved out to sea and low pressure troughs.  相似文献

We demonstrate a method for integrating environmental effects into a computable general equilibrium model. This is a critical step forward toward the development of improved integrated assessment models of environmental change. We apply the method to examine the economic consequences of air pollution on human health for the US for the period from 1970 to 2000. The pollutants include tropospheric ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, and particulate matter. We apply this method to the MIT Emissions Prediction and Policy Analysis (EPPA) model, a computable general equilibrium model of the economy that has been widely used to study climate change policy. The method makes use of traditional valuation studies, incorporating this information so that estimates of welfare change are consistent with welfare valuation of the consumption of market goods and services. We estimate the benefits of air pollution regulations in USA rose steadily from 1975 to 2000 from $50 billion to $400 billion (from 2.1% to 7.6% of market consumption). Our estimated benefits of regulation are somewhat lower than the original estimates made by the US Environmental Protection Agency, and we trace that result to our development of a stock model of pollutant exposure that predicts that the benefits from reduced chronic air pollution exposure will only be gradually realized. We also estimate the economic burden of uncontrolled levels of air pollution over that period. The uncertainties in these estimates are large which we show through simulations using 95% confidence limits on the epidemiological dose-response relationships  相似文献

根据2003年朝阳市大气环境监测资料,分析了朝阳地区大气污染的时间变化特征。研究结果表明:由于朝阳市存在工业布局不合理,生产工艺、污染处理设施落后等问题,市区大气污染问题较为突出;朝阳地区低空逆温频率偏高,而且贴地逆温强度相对较强,非贴地逆温平均底高相对较低,使得污染源排放的污染物在逆温层下输送扩散,不利于大气污染物的稀释。  相似文献

Results of joint calculations with meteorological WRF ARW model and chemistry transport CHIMERE model are considered as a basis of the modern system of the air quality assessment and forecasting. The system was designed in the Russian Hydrometeorological Center and Institute of Applied Physics of the Russian Academy of Sciences. Detailed prognostic information about the atmosphere state provided by the WRF ARW was used in the CHIMERE model for describing the air mass transport processes, chemical transformation, and pollution deposition. Results of retrieval and forecast of surface ozone concentration as one of main air quality indicators are under consideration. Calculations of ozone concentrations for different configurations of a prognostic system differ in resolution of model grid and in the way the boundary conditions are prescribed.  相似文献

The review is compiled based on the results of the operation of the total ozone (TO) monitoring in the CIS and Baltic countries functioning in the operational regime at the Central Aerological Observatory (CAO). The monitoring system uses the data from the national network with M-124 filter ozonometers under methodological supervision of the Main Geophysical Observatory. The quality of functioning of the entire system is under operational control based on observations obtained from the OMI satellite equipment (NASA, the United States). The basic TO observation data for each month of the first quarter of 2011 and for the quarter as a whole are generalized. Preliminary estimates of a large ozone anomaly in the Russian Arctic region are under consideration. The information about the surface ozone observations in the central Russian region is also considered.  相似文献

In this paper, the “Expérience sur Site pour COntraindre les Modèles de Pollution atmosphérique et de Transport d'Emissions” (ESCOMPTE) program is presented. The ESCOMPTE program is used to produce a relevant set of data for testing and evaluating regional pollution models. It includes high-resolution (in space and time) atmospheric emission inventories and field experiments, and covers an area of 120×120 km, centered over the Marseilles-Berre area in the southeast of France during Summer 2001. This region presents a high occurrence of photochemical pollution events, which result from numerous industrial and urban sources of primary pollutants. From the dynamical characteristics of the area, sea-breeze circulation and channeling effects due to terrain features highly influence the location of the pollutant plumes. ESCOMPTE will provide a highly documented framework for dynamics and chemistry studies.Campaign strategies and experimental set up are described. During the planning phase, existing modeling results helped defining the experimental design. The campaign involved surface measurement networks, remote sensing, ship-borne, balloon-borne, and airplane measurements. Mean standard meteorological parameters and turbulent fluxes, ozone, ozone precursors, photochemically active trace gases, and aerosols were measured. Five intensive observation periods (IOPs) were documented using a wide spectrum of instruments, involving aircraft (7) (one of them equipped with a Doppler lidar, the others for in situ meteorological and chemical measurements), constant volume balloons (33), ozone lidars (5), wind profilers (15 sodars and radars), Doppler scanning lidar (1), radiosonde systems (at 4 locations), instrumented ships (2). In addition to the air quality networks from environmental agencies, 15 supplementary ground stations equipped for chemistry and/or meteorology and/or surface flux measurements, were operational. All instruments were calibrated and compared during a Quality Control/Quality Assurance (QC/QA) week, at the very beginning of the campaign.Fifteen days were intensively documented during five IOPs, referenced as 1, 2a, 2b, 3, and 4. High pollution levels were encountered during sea-breeze conditions observed during IOPs 2b and 3, whereas IOPs 2a and 4 corresponded to moderate wind, and channeled plume regimes. In addition, hourly emissions inventories for all IOPs were established to complete data sets and to finalize the ESCOMPTE database (EDB).Two other projects were associated to ESCOMPTE: urban boundary layer (UBL) and tropospheric water vapor content by GPS tomography (GPS/H2O). They took advantage of the scientific environment provided by ESCOMPTE.  相似文献

Environmental artists have risen to the challenge of communicating the urgency of public action to address environmental problems such as air pollution and climate change. Joining this challenge, the immersive artwork Pollution Pods (PPs) was created through a synthesis of knowledge from the fields of environmental psychology, empirical aesthetics, and activist art. This study summarizes the scientific process in this transdisciplinary project and reports the findings from a questionnaire study (N = 2662) evaluating the effect of the PPs on visitors. Data were collected at the first two exhibitions of the installation, one in a public park in Trondheim, Norway, and one at Somerset House, London, UK. Intentions to act were strong and slightly increased after visiting the art installation. Individual changes in intentions were positively associated with self-reported emotions of sadness, helplessness, and anger and self-reported cognitive assessment their awareness of the environmental consequences of their action, their willingness to take responsibility for their consequences, and belief in the relevance of environmental problems for daily life. Education and age were negatively associated with intentions. Despite favorable intentions, however, taking advantage of an actual behavioral opportunity to track one's climate change emissions behavior after visiting the PPs could not be detected. We conclude that environmental art can be useful for environmental communication and give recommendations for communicators on how to best make use of it. We emphasize the potential benefits of art that encourages personal responsibility and the need for valid behavior measures in environmental psychological research.  相似文献
