Anhui Institute of Optics and Fine Mechanics (AIOFM) – Hefei Institute of Physical Sciences (HIPS)

Hefei Institutes of Physical Science, Chinese Academy of Sciences, formerly the Hefei Branch of CAS founded in 1978, is composed of 5 institutes, including Anhui Institute of Optics and Fine Mechanics (AIOFM), the Institute of Plasma Physics (IPP), the Institute of Solid State Physics (ISSP) and Hefei Institute of Intelligent Machines (IIM), and High Magnetic Field Laboratory (HMFL). Among them, AIOFM is a multidisciplinary institute engaging in both fundamental and applied researches of atmospheric optics, environmental optics, optical remote sensing and laser technology and engineering, especially with strong abilities for technological development. It studies atmospheric spectroscopic techniques, Differential Optical Absorption Spectroscopy (DOAS), Tunable Diode Laser Spectroscopy (TDLAS), Light Detection and Ranging (LIDAR) etc. It has a strong involvement in the remote sensing of the atmosphere, including the researches on the high resolution and high sensitivity absorption spectrum of atmospheric gases, observations of atmospheric aerosol, ozone and various pollutant gases from ground-based, airborne and balloon platforms.

Relevant to this project the Environmental Optics Centre of AIOMF is being involved. The Environmental Optics Centre has carried out DOAS research for more than ten years. Various DOAS systems (e.g. active DOAS, MAX-DOAS, mobile DOAS etc.) have been developed and applied in urban air quality monitoring, industrial emission, investigating pollutants distribution and transport and satellite validation. AIOFM MAX-DOAS systems and other optical remote sensing instruments play an important role in many major projects, such as Beijing 2008 Olympic Games and 2010 Shanghai Expo with the aim of investigation the air quality of these cities.

Main tasks
The main tasks are validation of NO2, SO2, HCHO, aerosols using observations from MAX-DOAS and mobile DOAS in the region of the Yangzi River Delta.
