英文摘要 | We propose a long-term parameterization scheme for two critical parameters, zero- plane displacement height ( d) and aerodynamic roughness length ( z0m), that we further use in the Surface Energy Balance System ( SEBS). A sensitivity analysis of SEBS indicated that these two parameters largely impact the estimated sensible heat and latent heat fluxes. First, we calibrated regression relationships between measured forest vertical parameters ( Lorey's height and the frontal area index ( FAI)) and forest aboveground biomass ( AGB). Next, we derived the interannual Lorey's height and FAI values from our calibrated regression models and corresponding forest AGB dynamics that were converted from interannual carbon fluxes, as simulated from two incorporated ecological models and a 2009 forest basis map These dynamic forest vertical parameters, combined with refined eight- day Global LAnd Surface Satellite ( GLASS) LAI products, were applied to estimate the eight- day d, z0m, and, thus, the heat roughness length ( z0h). The obtained d, z0m and z0h were then used as forcing for the SEBS model in order to simulate long-term forest evapotranspiration ( ET) from 2000 to 2012 within the Qilian Mountains ( QMs). As compared with MODIS, MOD16 products at the eddy covariance ( EC) site, ET estimates from the SEBS agreed much better with EC measurements ( R2 = 0.80 and RMSE = 0.21 mm day (-1)). |
