This paper describes the improvement of an atmosphere-soil-vegetation model and the validation of the new model by observation. In the previous performance test using measured data, some limitations were revealed in the schemes for the canopy radiation transmission and the stomatal resistance calculation, and are improved in this study. By these improvements, the observed albedo and latent heat flux are simulated more properly than before. Results of comparisons between calculations and observations for a winter wheat field and a grassland indicate that the predictability and applicability are improved by the introduction of the new schemes.
