Abstract: Unsworth and Monteith's aerosol attenuation coefficient τA was calculated with hourly cloudless sky data at Goose Bay, Montreal and Woodbridge (near Toronto) for the period 1968 to 1978. Turbidity was less on average (τA ...

Abstract: A spectrophotometer was used to determine surface emissivity of water samples in a laboratory. The results confirm a previous field result that emissivity is independent of water composition and is approximately equal to ...

Abstract: Micrometeorological data collected over cropped surfaces at Simcoe in southern Ontario are used to evaluate various evaporation rates. Data collected in 1971 from two plots of perennial ryegrass, one of which was irrigated, ...

Abstract: Field determinations of surface emissivity and temperature were carried out at the western end of Lake Ontario between July and November 1969. Emissivity was obtained from infrared thermometer measurements using an aluminum ...

Abstract: Transmissivities are determined for different cloud types using nine years of hourly irradiance measurements under overcast skies at six Canadian stations. Values for individual stations and for pooled data using irradiances ...
