英文摘要 | High-precision soil moisture products play an important role in estimating forest carbon storage and carbon emissions in Genhe, China. In this paper, we evaluated the Soil Moisture and Ocean Salinity (SMOS) L3 product, the Soil Moisture Active Passive (SMAP) L3 product, and four soil moisture products derived from the Advanced Microwave Scanning Radiometer 2 (AMSR-2), i.e., the Dual Channel Algorithm based on the Qp model (QDCA) product, the Japan Aerospace Exploration Agency (JAXA) L3 product, and the Land Parameter Retrieval Model (LPRM) C band and X band products in the Genhe area of China. The results indicated that the root-mean-square error (RMSE) and bias of the QDCA product were lower than those of the other AMSR-2 products, although the QDCA still fell outside of the acceptable range with a volumetric error of no greater than 6%. The JAXA product underestimated the soil moisture and had a constant bias of 0.089-0.099 m(3) m(-3). The LPRM C-band and X-band products had a constant variable season bias of 0.261-0.576 m(3) m(-3). The quality of the SMOS was better than that of the AMSR-2 products; however, the results were noisy and unstable. The SMAP was closest to the ground measurements and presented a low RMSE (0.039-0.063 m(3) m(-3)) and bias (0.022-0.050 m(3) m(-3)). Finally, an assessment was performed on the parameters in these soil moisture algorithms. |
