Abstract: The albedo of a variety of surfaces was measured for a total of approximately 400 hr with Middleton solari-albedometers whose outputs were recorded by a computer-controlled data acquisition system. The albedo for each ...

Abstract: Investigation into the nature and size of the divergence of net radiation at night in Canada's chinook belt showed that the mean rate of radiative cooling exceeded the measured cooling rate by a statistically significant ...

Abstract: Measured divergence of net nocturnal longwave flux between 1 and 3 m over a snow-covered field under clear skies and weak regional winds show that the rate of radiative cooling is higher than similar cooling rates over a ...

Abstract: In the winter of 1975/76 a helicopter was used to obtain temperature profiles across the city of Calgary. This operation was supported by airborne measurements of wind speed and lapse rate at the edge of the city, upwind. ...

Abstract: Surface and airborne temperature and air pollution data collected in Calgary's urban area show the formation of a multiple-celled heat island at street level. Temperature gradients and their variability correlated with ...

Abstract: The chinook is the best example of the family of mountain winds that blows in regions where long mountain chains lie more or less at right angles to the prevailing wind. Apart from the unseasonable warmth it brings to the ...

Abstract: Chinook winds bring unseasonably warm temperatures to southern Alberta in the winter. They also melt the snow and evaporate, the surface and near surface soil water. Hitherto, the warmth of the wind had almost exclusively ...
