The mitigation of air pollution in megacities remains a great challenge because of the complex sources and formation mechanisms of aerosol particles.The 2014 Asia-Pacific Economic Cooperation(APEC)sum
Over Eastern China(consist of Southern Eastern China and Northern East China),nitrogen dioxide(NO2),particulate matters with diameter less than 2.5 μm(PM2.5)and other air pollutants vary significantly
Particulate matter(PM)has been of great concern in China due to the increasing haze pollution in recent years.In 2012,the Chinese national ambient air quality standard(NAAQS)was amended with a "more s
作为主动遥感监测技术的激光雷达，能够获取近地面至高空10km 以内的大气气溶胶垂直分布，分析边界层演变的结构特征。通过结合激光雷达技术、近地面探测、空间气象场探测，初步构建“地空天一体化”的大气复合污染立体监测体系，对于理解、分析较重的灰霾污染来源、特征和变化趋势提供有力支撑。传统的大气颗粒物监测激光雷达仅能够进行垂直天顶方向观测，获取大气剖面特征，本文提出了一种基于振镜的快速扫描激光雷达技术(性
Transboundary air pollution due to atmospheric transport processes has been well recognized as a critical challenge for regional air quality and climate.Much less known is transfer of air pollutants a
将GRAPES-CUACE(Global-Regional Assimilation and Prediction System coupled with CMA Unified Atmospheric Chemistry Environment)气溶胶伴随模式用于2012 年11月北京市一次霾事件的关键源区追踪.天气分析表明，自19 日至20 日夜间，北京地面受高压弱气压场影响，白天为偏南风，夜
Long-term visibility measurements offer useful information for aerosol and climate change studies.Here we present our recent works converting station-based visibility measurements to gridded aerosol o
To ensure the good air quality for the 2014 APEC,stringent emission controls were implemented in Beijing and its surrounding regions,leading to a significant reduction in PM2.5 loadings.
四川南部城市群是成渝经济区的重要组成部分，其大气污染形势不容乐观.本研究以2006-2015 年四川南部的MODIS 3km 气溶胶光学厚度(AOD)日产品及地面观测数据为基础，利用本地CE318 地基观测数据对MODIS AOD 产品进行校验，确保AOD 产品的可用性；建立了AOD 与PM2.5/10之间的关系模型，并重点分析了川南城市群的大气灰霾时空分布特征及其成因.
含碳颗粒物是大气颗粒物的重要组成部分,主要包括有机碳(organic carbon,OC)、元素碳(elemental carton,EC)和少量碳酸盐(carbonate carbon,CC).含碳颗粒物通过直接、间接作用于辐射强迫,影响区域、全球气候变化.OC 的光散射作用和EC 的强吸光作用可不同程度地降低大气能见度；OC 中含有大量致癌、致畸、致突变物质,对人类健康构成巨大威胁.因此科学而
