Validation and sensitivity analysis of the snow thermal model (SNTHERM) at Binggou basin, Gansu[J]. Journal of Remote Sensing, 2011,15(4):792-810. DOI: 10.11834/jrs.20110160.
we evaluate the capability of a mass and energy balance computer modelsnow thermal model (SNTHERM.89) by simulating the snow properties with experimental data measured at Binggou basin
Gansu Province
China
2008. We also compare the simulated snow water equivalence (SWE) with the product from the advanced microwave scanning radiometer (AMSR-E).The results show that SNTHERM model could accurately predict the snow evolution process and snow properties at Binggou
and reasonably describe the characteristics of snow evolution
indicating that SNTHERM applied at Binggou successfully. In addition
we conduct the sensitivity analysis of snow properties to the meteorological forcing data and initial input parameters. It has been found that the solar radiation energy flux is the most sensitive parameter to the snow properties simulated by SNTHERM
such as the snow depth
density and the grain size. The snow properties are sensitive to their respective perturbation
while the snow density is sensitive to all the other properties. Hence
in the case that snow density need to predict accurately
