Space Weather and its Impacts

Space weather refers to the short-term variations in space environment that
affect space- or ground-based technological system, and in the worse case,
endanger human.

Intensive space weather storm could pose a wide range of hazards to human
activities.
–
Solar flares may disturb the ionosphere, resulting in degraded
communication and navigation quality
–
Solar energetic particles could damage the equipment of
spacecraft
–
Solar radiation effects on human being, effecting all cells, and
breaking DNA
–
Geomagnetic storms can generate GIC in power grids, and
disturb spacecraft magnetic attitude control
–
Themospheric disturbances may change the orbit, attitude and
life of spacecraft

Space Weather Monitoring and Forecasting
It is acknowledged in that space weather impacts humna activities and, similar
to the weather and climate, a monitoring and forecasting operation system of
space weather is needed to guarantee the further development of our society.

In 2002, CMA was authorized by the National Council
to establish the National Center for Space Weather
(NCSW), assigned to the National Satellite Meteorology
Center.
Missions of NCSW are:
To develop the ground- and space-based space weather
observation system;
To provide monitoring and forecasting products and services
for space weather users;
To steer development of the space weather and relevant
disciplines;
To participate international cooperation on space weather
hazards warning and mitigation.

Space Weather Monitoring and Forecasting
The ground-based space weather monitoring network has been
expanding in China.

About 20 stations are used to monitor the solar
activities, ionospheric and upper atmospheric
disturbances.

More than 500 GPS/MET stations in CMA are
available for routine TEC map product.

Space Weather Monitoring and Forecasting
The GOS satellites has become the ideal platform for space
weather observations.

Polar orbit satellites could globally monitor impacts of
energetic particles, such as, FY-3A/B, and POES,
Metop. FY-3 follow-ons will have aurora and
ionosphere capabilities.

Geostationary orbit satellites could monitor real-time
solar activities and in-situ energetic particles and
geomagnetic fields., such as, FY-2 and GOES series(OP) etc. FY-4 series and GOES-R/S will increase and
provide the solar imaging and/or geomagnetic field
observations

Space Weather Monitoring and Forecasting
The GOS satellites are unique and crucial, and the mission satellites
also provide important observations for space weather.

ACE/NASA monitors upstream solar wind
conditions and Interplanetary magnetic field
etc. for space weather community

SOHO and STEREO/NASA provide the
imagery of solar activities for space weather
forecast and research

NOAA will launch DSCOVR to replace ACE
and launch COSMIC-2 series

CMA is one of the major promoters and
participants of the “KuaFu” project

Public Awareness and Education
It is our mandatory to increase public awareness and education.
CMA currently delivers daily, monthly, and annual monitoring and forecasting
products and services to users through hard-copy bulletins, internet, phone, SMS,
e-mail, public media, etc.
CMA also provides special services for important customers, including
Shenzhou, ChangE, Beidou missions and State Grid, etc.

Space Weather Monitoring and Forecasting
In CMA, the application-oriented research and technology development
related to space weather provide significant support to operations.

Global Cooperation on Space Weather

Human activities are extending into space and becoming
vulnerable to space weather hazards;

Space weather impacts are both regional and global, Sharing
monitoring recourses and forecasting products and services;

Comprehensive international cooperation is necessary for the
mitigation of the societal and economic impact of severe space
weather event.
As the 24th solar maximum is approaching, we all need
to make a good preparedness together for possible
space weather hazards!

Summary

The potential loss due to space weather hazards could be mitigated
by the reliable monitoring, forecasting and service system;

Space weather spans national boundaries, and needs the effective
international cooperation;

As the natural extension of meteorology, space weather could be and
should be the integral component of “weather”;

CMA will continue to fully support the space weather activities of
WMO.
