E. Summary :

E-1. Object :

Accurate remote-sensing of aerosol (Asian-Dust) over Suwon, Korea

E-2. Necessity of Research :

Aerosol are one of the most important specie in atmosphere. To consider the physical and optical propertie of aerosol

and its affect other sources, the measurement by various device should be doing same time at same area. Lidar is most

effective tools to measure the vertical profile with high accuracy. ILE(institute for Laser Engineering) of Kyung Hee University

have been measured the aerosol and Asian-Dust from October, 1992. As a member of AD-NET, ILE will continuous measure

 the aerosol and asian dust in stratosphere and troposphere over Suwon Korea. Its results will be a great helpful to analysis the

characteristics of vertical and seasonal variation of Aerosol in North-ASIA.

E-3. Strategy of Research :

- Device Setup :

September 1992 - present (Ozone lidar in Suwon)

November 1995 - present (Aerosol lidar in Suwon)

May 1999 - present (Raman Lidar in Suwon)

- Measurement :

1 times in a week (Routine monitoring)

2-3 times in a week (Concentrate measurement for Asian-Dust)

2 times in a week for a specific correlative measurement

- Spatial and Temporal Resolution

5-10 minute for aerosol measurement in troposphere

10-20 minute for aerosol measurement in stratosphere and Raman

30 minute for ozone measurement in stratosphere
