The 5,400-kilogram Fengyun-4B satellite will be used for weather analysis and forecasting, and environmental and disaster monitoring.
Payloads include a Geostationary Interferometric Infrared Sounder, radiation imager, space environment packages for sensing high, medium and low energy particles, an imaging telescope for X-ray to extreme Ultraviolet activity monitoring, a geostationary high-speed imager and a lightning mapping imager.
The new payloads will improve China’s high-frequency monitoring of the atmosphere and observation ability of a number of smaller-scale and shorter-duration weather phenomena.
Fengyun-4B will operate in geostationary orbit at an altitude of 35,786 kilometers above the Earth for seven years, according to the China Meteorological Administration (CMA). This is an improvement over the five-year lifetime of the Fengyun-4A, launched late 2016. (...)

According to the China Meteorological Administration, Fengyun 4B adds new water vapor detection channels in its radiation imager, improved spectrum detection capabilities, and is capable if providing more accurate atmospheric radiation and temperature and humidity profiles.
CMA said Fengyun 4B also has a “newly equipped fast imager” with a resolution of about 820 feet, or 250 meters, to better monitor typhoons, rainstorms, and other extreme weather events. Fengyun 4B also has an improved data download system using Ka-band communications.
Like other satellites in China’s meteorological observatory fleet, Fengyun 4B data will be shared with international users, Chinese officials said.
“The measurement resolution and measurement sensitivity of the Fengyun 4B satellite are both doubled compared with the Fengyun 4A satellite, which can better serve meteorological forecasts,” said Dong Yaohai, the chief designer of the Fengyun 4 satellite series, in a statement released by the China Aerospace Science and Technology Corp.
Fengyun 4B will undergo a seven-month in-orbit test campaign before entering operational service, CMA said.
The new Fengyun 4 satellite series replaces China’s previous family of Fengyun 2 geostationary weather satellites. (...)
