RAMS/LEAF2/GEMTM model sensitivityevaluations for summer season climate

for the Mid-Atlantic, Southeastern Plainsand Western High Plains regions of theUnited States. The focus will be on the

impacts of land-use and land-coverchanges on surface fluxes, precipitation,

physical evaporation, transpiration, andsoil moisture. Runoff and floodingeffects may also be investigated.
