Assessment of the Noah-MP Land Surface Model Simulation Performance on the Water and Heat Fluxes of the Different Underlying Surface over Arid Region
In this study,using the observations from Janurary 2021 to Jane 2022 at the Zhangye National Climate Observatory and from Janurary to December 2020 at Daman Superstation over arid region,the simulation capabilities of the Noah-MP model were evaluated for water and heat fluxes on desert and cropland underlying surfaces.The results showed that:The R between the simulated and observed of radiation fluxes were greater than 0.98,and TSS were greater than 0.93,TSS of sensible heat flux was 0.809,which is larger than 0.504 of latent heat flux.The simulated variation of radiation and turbulent fluxes on the desert underlying surface were generally consistent with the observed values,which made the simulation better.The simulated 5 cm soil moisture had obvious response to the precipitation,showing obvious difference between cold and warm seasons,but its performance still needed to be improved.The R of radiation fluxes and soil temperature of each layer were greater than 0.98 and TSS were greater than 0.58,so the simulation capabilities of the NOAH-MP model for the radiation flux and soil temperature were reasonable,but the simulated latent heat flux and soil moisture of each layer were lower than the observations,and the simulation performance was not ideal especially in the growing season on the cropland underlying.Generally speaking,the simulation performance of NOAH-MP model on desert underlying surface was better than that on cropland over arid region.Optimization and development of hydrological process parameterization scheme in the model and consideration of anthropogenic effects in the model are important directions to improve the simulation performance of land surface model over arid region.
