| Abstract: | A reliable, easily operated, compact visibility meter has been developed for routine monitoring of atmospheric aerosol parameters. The meter operates on a principle similar to that of the integrating nephelometer.Visibilities (computed for a 2 per cent threshold) are measured from 5 km (polluted urban air) to 335 km (pure air) with an absolute accuracy of better than 15 per cent. |
