Investigation of Refractometer Measurements in the Atmosphere at High Relative Humidities and Temperatures

Abstract

When US Government drawings, specifications, or other data are used for any purpose other than a definitely related government procurement operation, the government thereby incurs no responsibility nor any obligation whatsoever; and the fact that the government may have formulated, furnished, or in any way supplied the said drawings, specifications, or other data is not to be regarded by implication or otherwise, as in any manner licensing the holder or any other person or corporation, or conveying any rights or permission to manufacture, use, or sell any patented invention that may in any way be related thereto. 11 FOREWORD This report describes research which is part of the graduate studies program of the Department of Physics, University of Western Ontario. The period of study extended from May 1st 1962 to April 30th 1963. The authors are indebted to Dr. P. A. Forsyth, F.R.S.C., Head of the Department, for making available the facilities of the department for this research program. Several members of the Tropospheric Physics Group, unde. >e direction of the senior author, have contributed towards the study reported here. Mr. H. C. Martin, M.Sc, has provided information on the air-flow about the capacitor-type refractometer, and has worked out the programs for computation on the IBM 650 Computer. Mr. J. Kortschinski, a student in the third year of the Engineering Science course at this university, has designed the wind tunnel and supervised its construction while working with the Group during the summer of 1962. Messrs. H. Aitkenhead, K. McColl and D. Stewart, technicians in the Group, have assisted in many aspects of the research program. H. £. Turner, the co-author, would like to acknowledge his indebtedness to the National Research Council of Canada for the Studentship awarded to him during the period of this study. The authors would like to express their sincere appreciation to those outside of the Department of Physics who have contributed in various ways to the research program: They arc grateful to the Chairman of the Defence Research Board and the Chief Superintendent of the Defence Research lelecommunications Establishment in Ottawa for the loan of some of the test instruments: to the Director of the Division of Applied Physics of the National Research Council in Ottawa for arranging for the calibration Ill of a precision resistor upon which the precise temperature measurements
