BOREAS HYD-04 AREAL SNOW COURSE SURVEY DATA

The BOREAS HYD-04 work was focused on collecting data during the winter field campaign (FFC-W) to improve the understanding of winter processes within the boreal forest. Airborne remote sensing data (gamma, passive microwave) were acquired along a series of flight lines established in the vicinity of the BOREAS study areas. Ground snow surveys were conducted along selected sections of these aircraft flight lines. These calibration segments were typically 10-20 km in length, and ground data were collected at 1- to 2-km intervals. The development and validation of remote sensing algorithms will provide the means to extend the knowledge of these processes and states from the local to the regional scale.

BOREAS HYD-04项目的核心工作为在冬季野外考察（FFC-W）期间采集数据，以加深对北方针叶林内冬季过程的理解。研究团队沿BOREAS研究区域周边布设的一系列飞行航线，获取了机载遥感数据（伽马射线、被动微波）；同时沿这些飞行航线的选定区段开展地面雪况调查。此类校准区段的长度通常为10至20千米，地面数据以1至2千米的间隔进行采集。遥感算法的开发与验证，将为将上述过程与状态的认知从局地尺度拓展至区域尺度提供有效支撑手段。
