The first set of observational images from the Fengyun-3H satellite (hereinafter referred to as “H-star”) were officially released. Currently, six of the nine remote sensing instruments onboard H-star have already been activated and are undergoing trial operations in orbit.

In addition to enabling remote sensing observation of various atmospheric elements such as temperature, humidity, and clouds, H-star can also simultaneously obtain remote sensing information on global greenhouse gases and auroras. In terms of global observation, H-satellite inherits 100-meter-class optical imaging capabilities, and its medium-resolution spectroscopic imager can conduct seamless global observations in multiple wavelength bands daily. In addition, microwave instruments such as microwave thermometers and microwave hygrometers conduct global observations in multiple wavelength bands, acquiring key parameters of the Earth’s multi-layered structure and supporting core meteorological tasks such as numerical weather forecasting.

The Fengyun-3 meteorological satellite also possesses high-frequency observation capabilities for the polar regions. The H satellite passes over both the North and South Pole 14 times a day, and the true-color images of the Antarctic acquired by the Moderate Resolution Spectroscopic Imager clearly capture the details of the polar ice and snow surface and cloud distribution. Furthermore, the Global Positioning Satellite Radio Occultation Observation System allows for quantitative observation of polar sea ice and snow cover. The microwave thermometer and microwave hygrometer also successfully captured the Arctic polar vortex and the first large-scale cold wave of the season, which affected China in October.
