研究目的
To present the most recent status of SMOS instrument performance and calibration after over 8 years in orbit as well as a hint on the lessons learnt and how they could be taken into account in future L-band missions.
研究成果
The paper concludes with the presentation of the most recent status of SMOS instrument performance and calibration after over 8 years in orbit, highlighting lessons learnt for future L-band missions.
研究不足
The study is limited by the design parameters of the SMOS mission that cannot be changed, focusing on mitigating effects from external factors such as the Sun and RFIs.
1：Experimental Design and Method Selection:
The study utilizes data from the SMOS mission, processed with both the operational version of the current Level-1 processor (v620) and a working version of a new processor (v720).
2：0). Sample Selection and Data Sources:
2. Sample Selection and Data Sources: Data from over 8 years of SMOS mission operation.
3：List of Experimental Equipment and Materials:
