摘要

The surface energy balance (SEB) is an important control on regional climates and hydrology. Long term measurements over forest sites are relatively rare, yet provide useful insight into seasonal and annual dynamics. Developing models to predict SEB fluxes is important for many applications, including the estimation of the SEB over data-sparse regions, and to fill gaps in flux data when observations are missing. This study evaluates the soil-canopy-air heat storage flux term and SEB closure over a mid-latitude deciduous forest. Using the forced closed fluxes, coefficients for simple models of three SEB terms are fitted and independently evaluated.
