Multichannel moderate-bandwidth filter instrument for measurement of the ozone-column amount, cloud transmittance, and ultraviolet dose rates.

Abstract

A six-channel moderate-bandwidth filter instrument for measurement of UV and visible radiation has been developed. The characteristic of the instrument are described, including the spectral and the angular responses. Furthermore the calibration procedure is outlined. Combining information from several channels, one may determine the total ozone-column amount, various biological dose rates, a cloud transmission factor, and the effective cloud optical depth. The methods used to determine these parameters are presented, and the measured parameters are compared with similar ones obtained from other instruments. The total ozone as measured by the instrument agrees with measurements from a standard Brewer to -0.05% +/- 2.04% over a two-year period. Two weeks of cloudless Commission Internationale de L'Eclairage dose rates agree with those from a Bentham double monochromator spectroradiometer to 0.99 +/- 0.03.
