  1. Retrospective data access • Purpose • To provide web-based access for selected data collections held on the NCAR MSS • Selection to be focused on datasets that serve a broad research community. • Examples: Community model simulations Multi-institution cooperative studies Long term atmospheric analyses • Current Status • Pilot Study Phase – not publicly available Public opening will be announced at www.scd.ucar.edu • Things are going well and we have many encouraging results

  2. Retrospective data access • Technological Design

  3. Retrospective data access • Pilot Projects • ACACIA (A Consortium for the Application of Climate Impact Assessments) NetCDF archive, LAS/Ferret system • NCEP Reanalysis Version 2 • Long term global atmospheric reanalysis of observed data • GrIB archive, LAS/NCL/DODS system • VEMAP (The Vegetation/Ecosystem Modeling Analysis Project) • NetCDF archive, TBD system • CCSM data serving project • Distribution of NCAR Community Climate System Model data • NetCDF archive, TBD system • GrADS/COLA project • MSS access to support research at the Center for Ocean-Land-Atmosphere Studies (COLA) • Binary, netCDF, GrIB archives, LAS/GrADS/DODS system

  4. Retrospective data access • LAS interface • User determines • Dataset, variable, space, and time domain • 1-D, 2-D for (x,y,z,t) graphical display • 1-D, 2-D, 3-D, 4-D file creation and download • User options • Contouring attributes, colors, lines, etc • Output file format, netCDF, ASCII, others?

  5. Retrospective data access • LAS Graphical Display • NCEP Reanalysis Version 2 • Temperature (°K) at 500 hPa • North America, Jan. 01, 1999, 00 GMT
