研究目的
To propose a new retrieval algorithm using Aquarius and SMAP satellites’ active and passive microwave observations to retrieve soil moisture products in different spatial scales and verify the results with ground observations.
研究成果
The new inversion algorithm successfully retrieves high-precision soil moisture products at two kinds of spatial scales in Naqu region. However, due to the underestimation of the surface's effective temperature by the satellite, the deviation was negative. The algorithm's applicability needs further global verification for wider future application.
研究不足
The satellite underestimated the effective temperature of the surface, leading to a negative deviation between the soil moisture products and the mean of the soil moisture observed by the stations. The applicability of the algorithm needs further verification in other global areas.
