Current Status of COSP within CAMhttp://www.cgd.ucar.edu/cms/jenkay/cosp/cosp.htm

  • MILESTONES ACHIEVED:

  • - COSP v1.3 (production version released June 25, 2010) implemented in-line within CAM4/CCSM4 using CAM I/O

  • - Compiles and runs with lahey or pgi fortran compiler on linux machine

  • Orbital sub-sampling and advanced namelist control for CFMIP experiments and ROSES09 project implemented

  • COSP and CAM-compatible COSP code on a branch in the CCSM repository

  • (https://svn-ccsm-models.cgd.ucar.edu/cam1/branches/cosp_cam4_1_01/).

  • STILL TO DO THIS SUMMER:

  • Make compatible with compilers on production platforms (e.g., bluefire, franklin)

  • Test implementation vs. published offline results (e.g., Zhang et al. (2010 JGR))

  • Make compatible with CAM5 physics

  • Compare COSP implementation and results with other modeling centers (NASA, GFDL, UKMet Office)

  • Generate curtain output?

  • Put CAM modifications for COSP onto trunk in the CCSM repository

  • Production runs for CFMIP5 (w/Haiyan Teng, Gary Strand)
