| 英文摘要 | The Sixth Phase of the Coupled Model Intercomparison Project (CMIP6) provides ample soil moisture (SM) products during 2015-2100, which are widely used in investigating future hydrological pattern. However, there remains limited understanding regarding the accuracy of multi -model CMIP6 SM future simulations following different Shared Socioeconomic Pathways (SSP). This study assesses the spatial-temporal accuracy of 22 CMIP6 model -derived SM products using 670 ground observation stations globally during 2015-2023. Each CMIP6 model encompasses SM estimations from SSP1-2.6 (The sustainable pathway), SSP2-4.5 (The medium pathway), and SSP5-8.5 (Fossil -fueled development). The latest Soil Moisture Active Passive (SMAP) and European Centre for Medium -Range Weather Forecast Reanalysis v5 -Land (ERA5-Land) SM products serve as reference benchmarks. The SM among three SSPs within the same model exhibits similar performance in in situ validation, the extended triple collocation assessment, and the classical seasonal decomposition trend analysis. This similarity may suggest a subtle variation in the influence of different SSPs on SM in the early stages of the future scenario. The majority of CMIP6 model -derived SM could reasonably capture the spatial distribution pattern and temporal evolution trend of the truth value. Meanwhile, noticeable discrepancies in accuracy, particularly regarding goodness -of -fit, are evident when compared to SMAP and ERA5-Land SM products. The CMIP6 models could provide better SM estimation in temperate and tropical zones than cold zones. In terms of differences between the land cover types, CMIP6 model -derived SM products perform well over various vegetated regions except for barren, where there are sequential overestimation and relatively low fitting degree. Extensive accuracy discrepancies exist among the 22 CMIP6 model -derived SM products due to variations in model parameterization methods and atmospheric variables. |
