Abstract

A summary of the accuracy of different snow gauges used in Canada is given. The results of field experiments carried out at the Cold Creek Hydrometeorological Research Station near Toronto demonstrated that the non-recording MSC Nipher shielded gauge displayed a superior catch efficiency compared to the Alter shielded Universal or Fischer & Porter recording gauges. The Fischer & Porter gauge had the lowest catch ratio of all gauges tested; yet, it is one of the most suitable gauges for operation at remote stations. Some of the implications for obtaining comparable precipitaton statistics for use in areal analyses and hydrologic models are discussed. Current research and development work on the Fischer & Porter gauge to increase its resolution to 0.25 mm resolution and to incorporate a built-in processing facility to correct for gauge catch deficiency is summarized.
