作为地球水文循环的一个组成部分，特别是在高纬度地区，降雪造成积雪堆积，反过来又提供了世界各地许多社区所需的大部分淡水资源。为了评估遥感积雪测量与现场测量之间的关系，2011/12年冬季在加拿大安大略开展了一个冬季实地项目，称为全球降水测量冷季降水实验。其目的是提供降水微物理学和与冷季降水有关的过程方面的信息，以支持利用GPM核心卫星上的双频降水雷达和无源微波成像仪以及星座成员卫星上的辐射计的GPM降雪量检索算法。多参数方法需要能够将雪的微物理特性的变化与可测量的参数联系起来，从而精确地确定雪的微物理特性。
AbstractAs a component of Earth’s hydrologic cycle, and especially at higher latitudes, falling snow creates snowpack accumulation that in turn provides a large proportion of the freshwater resources required by many communities throughout the world. To assess the relationships between remotely sensed snow measurements with in situ measurements, a winter field project, termed the Global Precipitation Measurement (GPM) Cold Season Precipitation Experiment (GCPEx), was carried out in the winter of 2011/12 in Ontario, Canada. Its goal was to provide information on the precipitation microphysics and processes associated with cold season precipitation to support GPM snowfall retrieval algorithms that make use of a dual-frequency precipitation radar and a passive microwave imager on board the GPM core satellite and radiometers on constellation member satellites. Multiparameter methods are required to be able to relate changes in the microphysical character of the snow to measureable parameters from which precip...
