| الوصف: | Continuous monitoring and assessment of satellite sensor radiometric response are crucial for timely detection of anomaly of the sensor performance, especially for operational optical sensors (e.g., FY-3D MERSI-II) beyond the expected lifespan. Improving calibration coefficients ensures the acquisition of high-precision and consistent observational Level 1 data records for long time-series researches. To evaluate the radiometric response stability of FY-3D MERSI-II in the reflective solar band, this study constructs parametric simplified and nonsimplified Warren bidirectional reflectance distribution function (BRDF) models using FY-3D MERSI-II nadir observation data at Dome C, Antarctica during the austral summer (October–February in next year) from 2019 to 2023. Subsequently, BRDF correction is applied to eliminate variations in the Dome C data caused by its non-Lambertian nature. The corrected data are analyzed for trends and compared with previous publications. The findings indicate that parameter simplification results in this study improve the calibration accuracy for band 3 (0.650 $\bm {\mu }\text{m}$) and band 4 (0.865 $\bm {\mu }\text{m}$) by 18.1% and 9.5%, respectively. Further analysis for the instrument degradation reveals that [the total multiyear degradation rate, average annual degradation rate] are within [$\pm$2.2%, $\pm$0.54%] and [$\pm$0.5%, $\pm$0.13%], respectively. Comparative validation results demonstrate good agreement with previous studies, showing a deviation of the average annual degradation rate between corresponding bands within $\pm$1%. It demonstrates that the stability of the MERSI-II is comparable to MODIS, which is one of the most frequently used medium-resolution sensors over last 25 years. |
