Modeling Effects of Land Cover Heterogeneity on Regional Climate and Hydrology in the Arctic
This project used a version of the regional atmospheric model RAMS that was developed for seasonal to interannual simulations to study the effects of land cover heterogeneity on the climate and hydrology of arctic Alaska. The model represents the effects of vegetation, seasonal permafrost evolution, snow accumulation, snowmelt, and the resulting changes in surface moisture and energy exchange. This researcher developed a coupled modeling system that incorporates a snow-transport model and a new, community land surface model. Although this project focused on an arctic domain, the modeling approaches will be valuable for other regions that have a high degree of landcover heterogeneity.
