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
Retrospective data access • Technological Design
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
