         African Climate Atlas
• Aims
  – Tangible product of VACS and CLIVAR
  – An original aim of VACS
  – Help to promote focus and research on African
    climate
  – Opportunity to draw together elements of African
    climate: West Africa, East Africa, southern Africa,
    central Africa, north Africa
  – Potential to serve African research community
  – Focus for evaluating numerical models
  – Provide a pointer to unanswered questions relating to
    the basic state
