Space Weather

FY-2 and FY-3 satellites carry Space Environment Monitors that monitor the flux and the energy spectrum of solar X-ray, high-energy proton, high-energy electron and heavy ion in polar-orbit and geostationary orbit, providing an important data source for space weather service.

A space-based and ground-based space weather monitoring network has been setup for systematic investigation on the solar, the space environment, the ionosphere and the upper atmosphere.

Space Weather observation Network
Space-based instruments
FY-3 spacecraft models (involve FY-3C/D/E)

– New ionosphere observations Ionospheric Photometer (IPM)
– Wide-angle Aurora Imager (WAI)
– GPS Occultation Sounder (GNOS)

FY-4 satellites

– New solar observations :Solar X-ray & EUV Imager (SXEI)
– Geomagentic field: FGM

Ground-based observations
Solar activity

– Solar optical telescope
– Solar radio telescope
– Solar magnetic field telescope

Middle and Upper Atmosphere and Ionosphere

– 5 ionosonde stations are constructing for providing ionogram data.
– 4 Scintillation stations are building.
– Riometer data from 3 riometer stations.

GPS network

TEC data over China from more than 300 GPS stations are available now. In near future, the number of GPS stations will increase to about 1000.

Space Weather Service
The NCSW/CMA publishes daily forecasts and alerts on the space weather events to users. Particularly, the products include short-term forecast, now-casting and warning, the weekly bulletin, the monthly bulletin, the annual bulletin, and the special event bulletin. Certain key parameters are issued every day. Space weather updates are released on the web, mobile phone, e-mail, and T.V, etc.

With the aid of a three-dimensional display and application platform developed by the National Center for Space Weather, people can display the radiation belt energetic particle and extrapolate to get the distribution of energetic particle in the altitude range from 400 to 1000 kilometers, providing space weather service for aircrafts flying the height.
