Abstract
Absorption attenuation of atmosphere in Shanghai Region was obtained for the first time for 4416A of He-Cd laser. The measurement was made at room temperature through atmosphere simulation in 10-meter long White cell. The results showed that the attenuation coefficient of atmosphere was $3.5 atm^{-1}km^{-1}$ for 4416A in Shanghai Region. According to the theoritical analysis, the attenuation of atmosphere for 4480A is $1.0526 km^{-1}$ where $1.034 km^{-1}$ is due to aerosols and $0.0186 km^{-1}$ due to gas molecules of atmosphere $components.^{(1)}$
