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

Deals with the systematic errors in climatic data produced by short-period and intermittent records, positioning of isolines on small-scale maps, a station network with only 23 permanent, mostly coastal stations for a 1,450,000 sq km area, imperfect instruments and sampling techniques, and observati...
