摘要

随着城市化和工业化的快速发展,环境退化已成为发展中国家面临的主要问题之一。在过去的几年里,由于城市化,孟加拉国面临着最糟糕的空气质量。为此,利用中分辨率成像光谱仪(MODIS)和多角度成像光谱仪(MISR)反演的气溶胶光学深度(AOD)数据,研究了2003 - 2016年季风季节孟加拉国上空AOD的时空分布、趋势分析和周期性特征。此外,我们还利用Mann-Kendall检验和Sen 's斜率对季风季节气溶胶的趋势分析进行了分析。利用小波相干分析(CWT)和连续小波变换(CWT)函数观测了AOD与蒸散发、潜热通量、降水、相对湿度、风速和地面气温等气象参数的周期相关性。MODIS和MISR反演的平均AOD在孟加拉国西部地区呈增加趋势,平均值分别在0.27 ~ 0.92和0.13 ~ 0.59之间。AOD在吉大港地区值最小,向孟加拉国西部地区有增加的趋势。此外,由于6月和7月的高降水冲淡了气溶胶,我们观察到季风季节AOD趋势不明显。平均AOD的年变率表现为2008年气溶胶浓度最大,2015年最小。MODIS反演AOD和MISR反演AOD的CWT在第2 ~第4周期表现出较强的周期性(> 0.9)。MODIS AOD和MISR AOD在2003-2016年也表现出一系列超前、滞后、同相和反相的情况,具有很强的交叉小波变换(XWT)功率,范围在0.0 ~ 1之间。根据研究结果,政府会采用不同的技术,例如植树造林、有效使用燃料、发展公共交通网络等,以降低微粒污染的浓度。

Spatial, Trend, and Wavelet Analysis of AOD Over Bangladesh

With the rapid increase in urbanization and industrialization environmental degradation is one of the major issues of developing countries. During the last couple of years, Bangladesh has faced the poorest air quality due to this urbanization. Therefore, in this study, we used Moderate Resolution Imaging Spectroradiometer (MODIS) and Multi-angle Imaging Spectro Radiometer (MISR) retrieved Aerosol optical depth (AOD) data to investigate the spatial–temporal distribution, trend analysis, and the periodic nature of AOD over Bangladesh during the monsoon season from 2003 to 2016. Moreover, we used the Mann–Kendall test and Sen’s slope to analyze the trend analysis of aerosol during monsoon season. We also used wavelet coherence analysis (CWT) and Continuous wavelet transform (CWT) function to observe the periodic correlation of AOD with different meteorological parameters i.e., evapotranspiration, latent heat flux, precipitation, relative humidity, wind speed, and surface air temperature. The average MODIS and MISR retrieved AOD showed an increasing trend in the western regions of Bangladesh with an average value ranging from 0.27 to 0.92 and 0.13 to 0.59 respectively. AOD showed minimum values in Chittagong divisions and tends to increase towards the western region of Bangladesh. Furthermore, we observe the insignificant AOD trend during monsoon season due to high precipitation levels during June and July that washout the aerosol. Moreover, the annual variability of average AOD showed the maximum concentration of aerosols in 2008 and while minimum during 2015. Furthermore, CWT of MODIS retrieved AOD and MISR retrieved AOD shows a strong periodicity (> 0.9) during the 2nd to 4th period. MODIS AOD and MISR AOD also show a series of leading, lagging, in-phase, and anti-phase situations for all years 2003–2016, having a strong cross-wavelet transform (XWT) power ranging from 0.0 to 1. Different techniques, such as afforestation, efficient fuel usage, the development of public transport networks, etc., would be employed in light of the study’s findings to lower the concentration of particle pollution.

期刊介绍: Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
