Abstract:
The paper describes the set – up and the possible applications of the Integrating Nephelometer Instrument. We have used the Nephelometer to measure the total scattering and backscattering coefficient and the hemispheric coefficient at three visible wavelengths (450, 550 and 700nm) for short and long-term measurements. All data are recorded and acquired with the NephLog software, compatible to record continuous long – term data. In addition, the optical properties of aerosol will be determined. The results acquired will be used in studies such as atmospheric visibility, radiative forcing and the extinction budget pertaining to aerosol particles. The temperature, pressure and relative humidity are also measured with the Nephelometer so that the state of the input aerosol can be estimated.
