Accurate, long-term, and continuous monitoring of Earth’s radiances is crucial for detecting subtle climate change signals. International expert teams are developing space-based reference systems to establish an SI-traceable radiometric benchmark in orbit. The High-Accuracy Onboard Calibrator (HAOC) is a pioneering pro...

Fengyun-3E wind radar (FY-3E WindRAD), as the world’s first global dual-frequency rotating fan-beam scatterometer, provides observations in both C-band and Ku-band. The original footprint scales of approximately 25 and 10 km, respectively, are similar to those of most spaceborne scatterometers and are insufficient for...

Microwave scatterometers are capable of acquiring land surface backscattering coefficients day and night under all-weather conditions, offering advantages for snow cover monitoring. However, the relatively low spatial resolution of traditional scatterometer data limits their application in the fine-scale monitoring of...
