New multiwave method and instrument for observation of atmospheric ozone and aerosol
Abstract
Description of an instrument for recording the spectrum of direct and scattered solar radiation in the wavelength range 3000-8000 A employing a double quartz monochromator is given. A logarithmic amplifier and special multialkaline photomultiplier remove the difficulty associated with the different intensity (by four orders of magnitude) at the opposite ends of the range scanned. Spectral sensitivity of the photomultiplier is maximum at 2900 A, falls to 1% of this maximum at 3500 A, and remains at this level for the rest of the spectrum. Also, a new multiwave method for atmospheric ozone measurements using nine wavelengths and accounting for aerosol errors is described.
