This award is for support of a three year collaborative program between the University of Colorado, Boulder and the University of Wyoming, Laramie to improve and validate glacier dynamic models. An isothermal, active glacier will be selected and the surface, englacial, and basal velocity field will be determined on a 3-D array of points over the glacier. These results will be used to test an improved top-down model, to compare top-down and bottom- up models, and to define further the constitutive law and sliding relations.

该奖项是为了支持科罗拉多大学博尔德分校和怀俄明大学拉勒米分校之间为期三年的合作项目，以改进和验证冰川动态模型。 将选择一个等温的活动冰川，并根据冰川上的 3D 点阵列确定表面、冰川和基底速度场。 这些结果将用于测试改进的自上而下模型，比较自上而下和自下而上模型，并进一步定义本构定律和滑动关系。
