"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.

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.

The Ozone Layer contains the proceedings of the Meeting of Experts on the Ozone Layer, organized by the United Nations Environment Programme and held in Washington, DC, on March 1-9, 1977. The papers review all aspects of the ozone layer, including the potential impact of stratospheric pollution and a reduction in the ozone layer on mankind, and encompass fields ranging from stratopheric physics and chemistry to biology, ecology, trade, and economics. This book is comprised of 23 papers and begins with a discussion on the environmental aspects of stratospheric ozone depletion and the effects of changing levels of ultraviolet radiation on phytoplankton, plants, timber production, and human health. Subsequent chapters explore some economic and social implications of a possible ban on the use of fluorocarbons; the link between atmospheric exchange processes and the ozone problem; and industry-sponsored studies on the effects of chlorofluorocarbons on the concentration of atmospheric ozone. The remaining chapters focus on stratospheric and ozone research activities in countries such as Canada, Germany, Italy, the Netherlands, United Kingdom, and the United States. This monograph will be a valuable resource for environmental scientists and policymakers.
