From 1962-1966, vertical distribution ozone measurements were made at 11 sites operated or supported by the Environmental Sciences Services Administration in the Western Hemisphere and in Antarctica. Observations made initially at several of the stations to provide information on instrument performance were followed by a major effort in data gathering during the International Quiet Sun Years (IQSY), 1964-1965. This first volume presents results, in the form of ozonagrams displaying ozone and temperature profiles, from the Western Hemisphere stations. Antarctic data will appear in Volume II. Supplementary data--coded values of ozone, temperature, and wind, applicable to standard and significant levels for all soundings--appear in O̲z̲o̲n̲e̲d̲̲a̲t̲a̲f̲̲o̲r̲t̲̲h̲e̲W̲̲o̲r̲l ̲d̲, published by the Meteorological Branch, Canadian Department of Transport. Computer tabulation sheets for IQSY Regener chemiluminescent ozonesonde data are available from the National Weather Records Center, Asheville, N.C.

Western hemisphere ozonagrams have been published in Volume 1.

"Regener chemiluminescent, Brewer-Mast electrochemical, and carbon-iodine electrochemical ozonesondes ... 1966 .... The field test, as well as supplemental laboratory tests, indicated a need for improvements in the three types of instruments."--Abstract.

Nimbus 3 infrared interferometer spectrometer (IRIS)measurements of the intensities in the 9.6-pn region are used to derive the ozone content in the atmosphere between latitudes SOON and 80's. The global distribution of total ozone was mapped for eight days in April and eight days in July 1969. These global maps of total ozone are compared with the upper-air oonstant pressure maps to emphasize the meteorological significance of the ozone variations in time and space. The total ozone has a minimum value of about 0.25 cm STP in the equatorial regions and increases markedly toward both poles. In the Arctic region, the total ozone in the spring time is well above 0.5 cm STP, while in summer it is about 0.4 cm STP. An eight-day mean global map of total ozone for April 1969 clearly reveals the presence of climatological large-scale ozone systems in the atmosphere. Another such map, for July 1969, shows that these systems have weakened considerably in the northern hemisphere. Seasonal variability in the total ozone over the southern hemisphere is much less pronounced. Close association between the total-ozone systems and tropospheric weather systems is shown for several cases. From this study, it is concluded that the atmospheric ozone, remotely sensed by satellites, can be used as a meteorological parameter to diagnose the present state of the atmosphere, and, thereby, aid weather prediction.
