Precipitation in Northern Quebec and Labrador: An Evaluation of Measurement Techniques

ABSTRACT. A testing of published maps of precipitation normals for a continen-tal subarctic area using hydrological techniques suggests a systematic annual error of 6 inches (152 mm.) The scope of the analysis is subcontinental, but point values for a central climatological station are used to eluci...
