In the upper atmosphere, ionosphere, magnetosphere. At present, there are a variety of advanced ground based instruments, such as proton magnetometer, fluxgate magnetometer, Digisonde, GPS ionospheric TEC and scintillation monitor, HF Doppler, all-sky meteor radar and airglow imager etc. The data monitoring and processing center can monitor the observation instrument working state in all stations and collect and process data through Internet. Some of processing data results can be published on the web near real time( http://space.iggcas.ac.cn ).
