  Brief introduction of NCC/BCC

• NCC was established in January, 1995 to
  provide climate related services and scientific
  researches.
• BCC (Beijing Climate Center:
  http://bcc.cma.gov.cn) was setup in March
  2003 based on NCC to extend NCC’s service
  domain. BCC has become one of the WMO’s
  regional climate center (RCC) on July,2009.
Structure of BCC
 Main Research and Services
• Monitoring, diagnostics and
  prediction/projection of climate over time
  scales ranging from monthly to century.
• Development of Climate System Models
• Impact assessment of climate variation
  and change
• Provide related services for China and
  eventually for Asia.
Main Operational Productions
• Monitoring/Diagnostics
• Predictions
• Assessments of climate change
  Impacts on socio-economic and
  ecological systems
