Airborne photometer measures absorption of ultraviolet. Automatically measures ozone concentrations in atmosphere to accuracy within 10 parts per billion. Air collected outside airplane enters photometer by way of transfer valve. Pressure and temperature of air measured simultaneously with transmissivity of air to ultraviolet light from lamp. Instrument has mass of 20.5 kg and fits in aluminum box measuring 78 by 58 by 25 cm. Compact, lightweight, low-power instrument developed for use on high-altitude research airplane.
