A CENTURY-LONG GLOBAL OFFLINE SIMULATION TOWARD LAND SURFACE, SNOW, SOIL-MOISTURE MODEL INTERCOMPARISON PROJECT (LS3MIP)

Abstract

 LS3MIP (The Land Surface, Snow and Soil moisuture Model Intercomparison Project) has been approved as Coupled Model Intercomparison Project Phase 6 (CMIP6) endorsed MIP to investigate climate forcing and land feedback. Land modeling groups of international community are preparing their model experiments under CMIP6 corrdination. In this study, we describe the overview of the model experiment design of LS3MIP. Also, we introduce the results from our test drive using MATSIRO for checking whether the experiment configuration accords with the protocol. The results show that inter-annual trends of runoff, snow cover fraction, soil moisture and evapotranspiration in global scale are reproduced observational variability properly. Results suggest that water balance tend to decrease around Himalaya Mountains in the 20th century. This is probably due to negative trend of precipitation in the region.
