摘要
大气气溶胶地基遥感监测由于其精度高、参数多、易于维护等特点,近几十年里发展迅速。CE318型太阳光度计作为地基遥感监测的基本仪器,在美国NASA建立的气溶胶自动监测网AERONET的影响下,越来越普及。中国正在逐步建立和完善以CE318为基础的气溶胶自动监测网。本文简单介绍了CE318型太阳光度计的基本结构和功能,详细介绍了其高精度分光探测、高精度太阳跟踪和自动化测量三个方面的关键技术,并对仪器误差来源做了深入分析,为基于CE318的气溶胶地基遥感监测提供支持。
Due to its high precision,multi-parameter, easy to maintain,Ground-Based Remote sensing monitoring of atmospheric aerosol has developed rapidly in recent decades.Sun photometer CE318 is the main instrument for ground- based remote sensing monitoring.It is becoming increasingly popular under the influence of AERONET established by NASA.The automatic aerosol remote sensing monitoring network based on CE318 is improving gradually in China.This presentation briefly introduced the basic structure and function of CE318 sun photometer, and presented in detail its three key technologies of high precision spectrometer detection,high precision sun-tracking and automated measurement,in addition,analyzed its error sources.These studies provide support to aerosol remote sensing monitoring based on CE318.
