  • 18. Agency 2 Crowd• Traditional web delivery interface• Capacity issues with near real time delivery • e.g. Victorian bush fires 2009• Presents a view • Web services will allow integration into end-user applicationsGA information on natural disasters
  • 19. Agency 2 Crowd (A2C) issues • Data volumes are increasing rapidly – Spatial & spectral resolution both increasing Volume of worldwide climate data is expanding rapidly, creating challenges for both physical archiving and sharing, as well as for ease of access and finding what’s neededOverpeck, J.T., Meehl, G.A., Bony, Easterling,D.R., 2011: Science 331,700 -702. GA information on natural disasters
  • 20. Agency 2 Crowd • Cloud computing assists with: – Storage capacity – Computation capacity – Delivery speed – Increased reliability – Surge capacity • But… at the petascale traditional databases breakGA information on natural disasters
