ABSTRACT:
An apparatus and method for measuring ozone in the atmosphere. The apparatus utilizes a fiber optic cable connected to a collimating lens located outdoors and a spectrometer that is located indoors. A pan-and-tilt positioning unit having a pan-axis capable of tracking an azimuth angle of the Sun, and a tilt-axis capable of tracking an elevation angle of the Sun, is utilized for automatically pointing the collimating lens directly at the Sun and taking readings for column ozone determination on any given day of the year. The apparatus and method utilizes a computer that is in electrical communication with the spectrometer and the pan-and-tilt unit.
