Abstract

Knowledge of aerosol distribution and trends in the total atmospheric column as well as at different vertical levels of the atmosphere can provide crucial inputs to understand the role of aerosols in the changing climatic scenario. Indian region is one of the major aerosol hotspots and it is therefore important to have a continuous monitoring of varying aerosol trends over both land and surrounding water bodies. Several studies have been already carried out to investigate the aerosol changes over Indian mainland. This study provides insight into the columnar and vertical distribution as well as trends of aerosols over six oceanic zones surrounding the Indian region over the Arabian Sea (AS) and the Bay of Bengal (BoB) waters during winters and post-monsoons (2010–2019). The work has been carried out using the Level 2 aerosol datasets from space-borne Cloud-Aerosol Lidar with Orthogonal Polarisation (CALIOP) onboard Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) mission, Dark Target algorithm data products from Moderate Resolution Imaging Spectroradiometer (MODIS)/Aqua sensor as well as the model reanalysis products from Modern-Era Retrospective Analysis for Research and Application–2 (MERRA-2) Reanalysis. The Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) back trajectory frequency cluster analysis has also been carried out to explore the possible sources of aerosols. The variability of planetary boundary layer height from European Centre for Medium-range Weather Forecasts Re-Analysis–5 (ECMWF ERA 5) Reanalysis products in connection with changes in aerosol distribution has also been discussed.

印度大陆周围海洋地区最近的年代际气溶胶趋势

了解气溶胶在大气总柱以及不同垂直水平的分布和趋势，可以为了解气溶胶在不断变化的气候情景中的作用提供重要的投入。印度地区是主要的气溶胶热点之一，因此对陆地和周围水体的不同气溶胶趋势进行持续监测很重要。已经进行了几项研究来调查印度大陆上空的气溶胶变化。这项研究深入了解了冬季和季风后（2010-2019年），阿拉伯海（as）和孟加拉湾（BoB）水域印度地区周围六个海域气溶胶的柱状和垂直分布以及趋势。这项工作是使用带有正交偏振的星载云气溶胶激光雷达（CALIOP）和红外探路卫星观测（CALIPSO）任务的2级气溶胶数据集进行的，来自中分辨率成像光谱仪（MODIS）/Aqua传感器的暗目标算法数据产品，以及来自现代研究与应用回顾分析-2（MERRA-2）再分析的模型再分析产品。还进行了混合单粒子拉格朗日积分轨迹（HYSPLIT）后轨迹频率聚类分析，以探索气溶胶的可能来源。还讨论了欧洲中期天气预报中心重新分析-5（ECMWF ERA 5）重新分析产品中行星边界层高度与气溶胶分布变化的可变性。

期刊介绍： ASE is an international journal that publishes high-quality papers, communications, and discussion that advance aerosol science and engineering. Acceptable article forms include original research papers, review articles, letters, commentaries, news and views, research highlights, editorials, correspondence, and new-direction columns. ASE emphasizes the application of aerosol technology to both environmental and technical issues, and it provides a platform not only for basic research but also for industrial interests. We encourage scientists and researchers to submit papers that will advance our knowledge of aerosols and highlight new approaches for aerosol studies and new technologies for pollution control. ASE promotes cutting-edge studies of aerosol science and state-of-art instrumentation, but it is not limited to academic topics and instead aims to bridge the gap between basic science and industrial applications. ASE accepts papers covering a broad range of aerosol-related topics, including aerosol physical and chemical properties, composition, formation, transport and deposition, numerical simulation of air pollution incidents, chemical processes in the atmosphere, aerosol control technologies and industrial applications. In addition, ASE welcomes papers involving new and advanced methods and technologies that focus on aerosol pollution, sampling and analysis, including the invention and development of instrumentation, nanoparticle formation, nano technology, indoor and outdoor air quality monitoring, air pollution control, and air pollution remediation and feasibility assessments.
