INVESTIGATION OF REFRACTOMETER MEASUREMENTS IN THE ATMOSPHERE AT HIGH RELATIVE HUMIDITIES AND TEMPERATURES

Abstract

Two techniques for the precise measurement of changes in air refractivity within the troposphere are examined in the present study. These are the microwave refractometer which uses a ventilated metal cavity as the sensing element, and the Hay refractometer whose sensing element is in air capacitor. The effects of water vapour adsorption and condensation upon the sensing elements of these instruments at high relative humidities make the interpretation of such soundings uncertain, in view of the conflicting evidence of previous workers. This report describes a laboratory study of the interaction between the refractometer sensors and the air humidity.
