Measurement of atmospheric extinction coefficient in the visible spectral region at Bangi, Malaysia

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The purpose of this study is to determine the total optical thickness for different atmospheric extinction and for different wavelengths through the visible region. A portable Avantes AvaSpec ULS 2048X64-USB2 spectrometer was used, over Bangi (2°55' N, 101°46' E, and 50 m above sea level) in Malaysia. Experimental techniques, sample observation, are presented for obtaining atmospheric extinction from spectrometer measurement. The study has revealed that the total atmospheric extinction for the wavelength 400 nm,500 nm, 600 nm, and 700 nm under cloudless sky was successful obtained by Langley methods.
