Remark

RWCC

As a member of International Space Environment Service (ISES), Regional Warning Center of China (RWC-China) consists of four sub-centers: Solar Activity Prediction Center, Space Environment Prediction Center, Ionospheric Distrubance Prediction Center and Geomagnetic Storm Prediction Center. The headquarters of RWC-China is located in the campus of National Astronomical Observatories, Chinese Academy of Sciences (NAOC). The tasks of RWC-China are as follows: improvement for space weather forecast; enlargement of the service field; collaboration with domestic and international organizations; exchange forecast information and observational data with other regional warning centers to serve the users in local regions and the world.
