摘要：Abstract. Prior to the beginning of the World Meteorological Organization's(WMO) Solid Precipitation Inter-Comparison Experiment (SPICE, 2013–2015),two precipitation measurement intercomparison sites were established inSaskatchewan to help assess the systematic bias in the automated gaugemeasurement of solid precipitation and the impact of wind on the undercatchof snow. Caribou Creek, located in the southern boreal forest, andBratt's Lake, located in the southern plains, are a contribution to theinternational SPICE project but also to examine national and regional issuesin measuring solid precipitation, including regional assessment of wind biasin precipitation gauges and windshield configurations commonly used inCanadian monitoring networks. Overlapping with WMO-SPICE, the Changing ColdRegions Network (CCRN) Special Observation and Analysis Period (SOAP)occurred from 2014 to 2015, involving other enhanced observations and coldregions research projects in the same geographical domain as theSaskatchewan SPICE sites. Following SPICE, the two Saskatchewan sitescontinued to collect core meteorological data (temperature, humidity, windspeed, etc.) as well as precipitation observations via several automatedgauge configurations, including the WMO automated reference and theMeteorological Service of Canada's (MSC) network gauges. In addition, manualsnow surveys to collect snow cover depth, density, and water equivalent werecompleted over the duration of the winter periods at the northern CaribouCreek site. Starting in the fall of 2013, the core intercomparisonprecipitation and ancillary data continued to be collected through thewinter of 2017. Automated observations were obtained at a temporalresolution of 1 min, subjected to a rigorous quality control process, andaggregated to a resolution of 30 min. The manual snow surveys at CaribouCreek were typically performed every second week during the SPICE fieldprogram with monthly surveys following the end of the SPICE intercomparisonperiod. The Saskatchewan SPICE data are available at https://doi.org/10.18164/63773b5b-5529-4b1e-9150-10acb84d59f0 (Smith and Yang, 2018). The datacollected at the Saskatchewan SPICE sites will continue to be useful fortransfer function testing, numerical weather prediction and hydrologicalforecasting verification, ground truth for remote-sensing applications, aswell as providing reference precipitation measurements for other concurrentresearch applications in the cold regions.
