China's meteorological authority released the first set of images from the newly launched Fengyun 4C satellite on Saturday, in a demonstration of its ability to monitor conditions from the Sun to Earth in near real time.
Launched on Dec 27 from the Xichang Satellite Launch Center in Sichuan province, the craft is currently the most capable single geostationary meteorological satellite in orbit in terms of comprehensive observation capability, according to the China Meteorological Administration.
The satellite is equipped with six payloads that meet advanced international standards. Images released show clear textures and rich details captured by the satellite's geostationary radiation imager, the administration said.
Among them, the interferometric atmospheric vertical sounder provides highly refined spectral data capable of capturing the vertical structure of the atmosphere. The information is expected to supply additional observation data for Earth system numerical forecasting and improve weather prediction accuracy.
A lightning imager aboard the satellite has produced continuous observation animations that accurately depict lightning activity during severe convective storms, demonstrating its potential for monitoring extreme weather and providing early warnings.
Meanwhile, the multiband ionospheric ultraviolet spectrometer imager has conducted continuous observations of airglow phenomena over the Eastern Hemisphere. The instrument can map structural changes in Earth's ionosphere that may affect communication, navigation and positioning signals, the administration said.
It added that a solar extreme ultraviolet imager, working together with solar X-ray and ultraviolet flux sensors, successfully captured image sequences and radiation changes during solar flare eruptions, which will help expand China's ability to track solar activity.
With 10 Fengyun weather satellites currently operating in orbit, China is the only country with meteorological satellites covering four near-Earth orbital types, according to the administration.
