Abstract

The Aerosol Optical Depth (AOD) has measured using remote sensing and GIS methods, with MODIS data collected in Jharkhand from 2011 to 2017. The state's eastern and northern borders have greater aerosol loadings (AOD: >0.5) while the southern and western parts have lower aerosol loadings (AOD: <0.3). Primary, secondary, tertiary, and quaternary aerosol sources have been identified and categorized using the Analytic Hierarchical Process (AHP). Only 1.29% of the study area, which still emits the most aerosols, is covered by primary sources. Industrial zones, mining regions, thermal power plants, cement industries, high road density, and stone crushers are found in many locations throughout the country. Secondary sources of aerosols account for 5.23% of the study and are located near the main sources. The quaternary (54.08%) and tertiary (39.4%) aerosol sources mainly covered the Southern, Western, and North-Western portions of the state, which is enveloped by a heavily vegetated region. AOD, sources of aerosols, wind direction, and velocity were examined here. There were non-separable connections in this area and also AOD distribution is connected to aerosol sources, wind direction, and wind velocity. Finally, it employs the AOD values to identify different aerosol kinds and source heterogeneity to elucidate their influence.

摘要

气溶胶光学深度 (AOD) 是使用遥感和 GIS 方法测量的，其中 MODIS 数据是从 2011 年到 2017 年在贾坎德邦收集的。该州东部和北部边界的气溶胶载荷更大（AOD：>0.5），而南部和西部地区则有更大的气溶胶载荷（AOD：>0.5）较低的气溶胶负载（AOD：<0.3）。一级、二级、三级和四级气溶胶源已使用层次分析法 (AHP) 进行识别和分类。只有 1.29% 的研究区域（仍然排放最多的气溶胶）被主要来源覆盖。工业区、矿区、火力发电厂、水泥工业、高密度道路和碎石机遍布全国许多地方。气溶胶的次要来源占研究的 5.23%，且位于主要来源附近。第四纪 (54. 08%) 和三级 (39.4%) 气溶胶源主要覆盖该州的南部、西部和西北部，这些地区被植被茂密的地区所包围。此处检查了 AOD、气溶胶来源、风向和速度。该区域存在不可分离的联系，AOD分布也与气溶胶源、风向和风速有关。最后，它使用 AOD 值来识别不同的气溶胶种类和来源异质性，以阐明它们的影响。风向，风速。最后，它使用 AOD 值来识别不同的气溶胶种类和来源异质性，以阐明它们的影响。风向，风速。最后，它使用 AOD 值来识别不同的气溶胶种类和来源异质性，以阐明它们的影响。
