Abstract: A study is made of the dependence of daytime net all-wave radiation on global solar radiation for clear days and also for monthly mean values. Published data from Guelph, Ottawa and Toronto for the years 1946?66 are used. ...

Abstract: A new method for the measurement of the net flux of radiation from shipborne sensors is described. In this method two matched Funk net pyrradiometers are mounted, one on each side of the ship. Each sensor is gimbal mounted ...

Abstract: A method of evaluating the atmospheric turbidity coefficient from global solar radiation and diffuse sky radiation is formulated. By application of the present method, the turbidity coefficient is evaluated at urban ...

Abstract: An instrument for direct measurement of vapor pressure and vapor pressure gradient (and similarly for temperature) has been designed and constructed. Thermistors are used as wet-and dry-bulb thermometers in the adjacent ...
