The Role of SW ServicesllService	  is	  an	  important	  part	  in	  SW	  opera0on
Service	  is	  the	  start	  point	  and	  ﬁnal	  goal	  of	  the	  SW	  opera0on
̶ Analyze	  requirements	  of	  users
̶ Facilitate	  exchanges	  of	  informa8on	  between	  users	  and	  scien8sts	  to	  promote	  poten8al	  applica8ons
̶ Facilitate	  development	  of	  SW	  observa8on	  and	  forecas8ng
̶ Deliver	  SW	  informa8on	  to	  users	  to	  mi8gate	  SW	  eﬀects	  on	  technological	  systems

Public Service & User Trainingl

Public	  services	  generally	  refer	  to	  public	  educa0on	  and	  training,	  such	  as̶ exchanging	  forecas8ng	  techniques	  and	  exper8se
̶ exchanging	  knowledge	  on	  user	  requirements
̶ providing	  public	  educa8on	  and	  outreach	  material

Public Services
NCSW currently delivers SW services products to users through hard-copybulletins, internet, cell phone message, e-mail, special column of the China
Meteorological Newspaper, and TV, etc.

We	  have	  broadcasted	  space	  weather	  forecas0ng	  on	  CCTV	  for	  several	  0mes	  so	  that	  the	  public	  can	  acquire	  SW	  informa0on	  immediately.	  Public Services

Eﬀects	  of	  severe	  space	  weather	  events
SW	  can	  inﬂuence	  the	  performance	  and	  reliability	  of	  space-­‐borne	  and	  ground-­‐based	  technological	  systems,	  and	  can	  endanger	  human	  life	  or	  health	  of	  astronaut	  crews	  outside	  the	  magnetosphere,	  as	  well	  as	  avia0on	  ﬂight	  crews	  and	  passengers	  on	  trans-­‐polar	  ﬂights.	  

The	  growing	  importance	  of	  space	  to	  security	  and	  economic	  wellbeing	  requires	  we	  develop	  the	  eﬀec8ve	  emergency	  response	  to	  mi8gate	  the	  deleterious	  eﬀects	  of	  severe	  space	  weather.

Based	  on	  our	  analysis,	  the	  satellite	  company	  decrease	  their	  response	  8me	  of	  one	  of	  anomalies	  from	  30	  minutes	  to	  about	  1	  minute.

When	  Wenchuan	  Earthquake	  occurred	  on	  May	  12th,	  we	  responded	  immediately,	  to	  make	  special	  bulle8n	  and	  take	  part	  in	  Na8onal	  Meteorological	  Center	  of	  CMA’s	  mee8ng.	  Users Conference in May, 2012
Requirement	  Analysis

The	  theme	  was	  to	  exchange	  experiences	  in	  terms	  of	  the	  SW	  services,	  learn	  the	  demands	  in	  avia8on	  safety,	  satellite	  communica8on	  and	  aerospace	  TT&C	  so	  as	  to	  improve	  China's	  SW	  forecas8ng	  and	  warning	  services.

• With	  the	  increasing	  use	  of	  satellite	  systems	  in	  the	  modern	  society	  the	  need	  of	  improved	  services	  in	  space	  weather	  monitoring	  and	  forecas8ng	  is	  obviously	  becoming	  crucial.	  
• Before	  10th	  anniversary	  of	  NCSW,	  SW	  users	  conference	  was	  held	  in	  Beijing.
