Recent studies have highlighted the importance of the heat release from the southern side of the Himalayas for the development of South Asian Summer Monsoon.However,studies related to land surface heat fluxes are nonexistent on the southern side.In this study we test the feasibility of deriving land surface heat fluxes on the central Himalayan region using Topographically Enhances Surface Energy Balance System (TESEBS).Land surface heat fluxes were derived using MODIS land surface products and global land data assimilation system (GLDAS) meteorological data as input forcing to the model.The model results were validated using the first eddy covariance measurement system established in the central Himalayas.The derived land surface heat fluxes were close to the field measurements with mean bias of 15.96,-19.89,8.79 and -20.39 W m-2 for net radiation flux,ground heat flux,sensible heat flux and latent heat flux respectively.
