DOBSON OZONE MEASUREMENTS OBTAINED ON THE NASA MOBILE LAUNCH EXPEDITION NO. 1,
Abstract:
A Dobson Spectrophotometer was operated on a ship to measure total atmospheric ozone from 38 degrees N. to 60 degrees S. near 80 degrees W. during February-April 1965. Aboard ship it is possible to obtain internally consistent data over wide ranges of latitude and longitude and across regions of particular interest. With two operators, observations could be made in light and moderate seas. The effects of misalignment due to ship motion were determined. Instrument calibration procedures and corrections to the data are discussed, and the total ozone data are tabulated. Comparison with nearby fixed stations shows good agreement. By use of data from other fixed stations near 80 degrees W., the latitudinal curve of total ozone is extended to 75 degrees N. and 90 degrees S. Major features are a broad equatorial minimum centered at 8 degrees S., an increase to a plateau at high northerly latitudes, and maxima at 47 degrees S. and 90 degrees S. Author
