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

Аннотация

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 observational and recording errors, all of which apply to the Labrador-Ungava region. Indirect methods for adjusting precipation gage data: snow surveying, stream gaging, interception and evapotranspiration calculations and watershed rain gage networks, are discussed. The results, which necessarily are only speculative, suggest a systematic annual error of 6 in.
