Abstract
A method for measuring total column ozone in the atmosphere and an instrument for implementing this method is disclosed. The ozone meter generally includes a first photodetector sensitive to UV-B only, a second photodetector sensitive to visible light only, a position-sensitive detector for measuring solar zenith angle and a microprocessor for normalizing the UV-B response relative to the visible response and applying one or more stored algorithms to the measured and normalized UV-B value and solar zenith angle to correlate total column ozone to a set of measured or modeled surface irradiances covering a wide range of solar zenith angles and total column ozone values.
