Accurate understanding of land surface is essential to analyze energy exchanges between earth surface and atmosphere. For
the quantization of energy fluxes, the various researches about Land Surface Model(LSM) have been progressed. Among the
various LSMs, the researches using Common Land Model(CLM) and Variable Infiltration Capacity(VIC) model are performed
briskly. The CLM which is advanced LSM can calculate realistic results with few user defined parameters. The VIC model
which is also typical LSM is widely used for estimation of energy fluxes and runoff in various fields. In this study, the energy
fluxes which are net radiation, sensible heat flux, and latent heat flux were estimated using CLM and VIC model at Southern
Sierra-Critical Zone Observatory(SS-CZO) site in California, United States. In case of net radiation and sensible heat flux,
both models showed good agreement with observations, however, the CLM showed underestimated patterns of net radiation
and sensible heat flux during precipitation period. In case of latent heat flux, the CLM represented better estimation of latent
heat flux than VIC model which underestimated the latent heat flux. Through the estimation of energy fluxes and analysis
of models’ pros and cons, the applicability of CLM and VIC models and need of multi-model application were identified.
