Abstract

In situ data from around the globe are used to evaluate the parameterization of the fraction of soil ice over total moisture (f_i) as used in four weather and climate models. Based on these evaluations and data analysis, an overall realistic (empirical) formulation is developed to compute f_i as a function of soil temperature and the ratio of total moisture over its saturated value. This new formulation is found to reduce the winter ground temperature by up to 3 K over high latitudes in the offline Community Land Model (CLM3) simulation.
