Remote Sensing of Environmental Change in Cold Region

这项研究将支持整个寒冷地区新出现的一系列环境问题，更具体地说，湖冰是气候变化的前哨。它将研究北方大湖的反应，并在中尺度数值模型中纳入对地表和次表层过程的卫星观测。该研究计划将侧重于以下主题：1）了解过去，现在，和预测的北方湖冰物候和厚度，2）调查冰条件的变化和湖水属性之间的相互作用3）表征和预测湖冰次表层-表层-大气相互作用和交换过程在不断变化的气候中使用先进的遥感技术。

This research will support the emerging spectrum of environmental issues throughout cold regions, more specifically, lake ice as a sentinel of climate change. It will study the response of Northern large lakes and incorporate satellite observations of surface and subsurface processes in mesoscale numerical models. The research program will focus on the following themes: 1) understanding past, present, and projection of Northern lake ice phenology and thickness, 2) investigating the interplay between ice condition variability and lake water attributes 3) characterization and projection of lake ice subsurface-surface-atmosphere interaction and exchange processes in a changing climate using advanced remote sensing techniques.
