  1. G-RSM CVS System at ECPC Hideki Kanamaru Scripps Institution of Oceanography 7th Annual RSM Workshop July 2006, Israel

  2. Installation • Install CVS (http://www.nongnu.org/cvs/) • C and Fortran compilers required (we usually use portland group compilers on Linux machines) • Set environmental variable CVSROOT (e.g. setenv CVSROOT :pserver:anoncvs@rokka.ucsd.edu: /rokka1/kana/cvs-server-root/cpscvs

  3. Installation • $ cvs co Install [Note Capital “I”] • You will get “inst” and “install” scripts. “inst” is a wrapper script that calls “install” • ./inst [model version] [topography option] • [model version] rsm_frozen, rsm_latest, crsm_frozen, gsm_frozen, gsm_latest, scm_latest • [topography option] hi (use 30 seconds gtopo30 topography) or lo (use 4minutes topography)

  4. Installation Installer will ask you: • Which model [rsm/gsm/crsm/scm] • Machine architecture [single/thread/mpi/hybrid] • Institution [ecpc/sdsc/ncar, etc] choose ecpc if not available • Machine name [ibmsp/dec/cray/intel/linux, etc] • Model resolution [e.g. T62L28 r54x55, T62L28 r8167c5487] you have to create resolution definition files in rsm/def if you want to define your own domain • Which script [rsm/rsim/csim, etc] rsm is for testing purpose (48hours integration). rsim is for downscaling with global files. csim is for crsm (c2r).

  5. Installation • You can choose to use “install” script. • ./install --model=[rsm/gsm/crsm/scm] --version=[…] --enable-[numerous options] • --enable-osu2 • --enable-noah • --enable-cldw-zc : Zhao-Carr cloud water scheme • --enable-cldw-sy3n: Song-You Hong cloud water scheme • --enable-cldw-sy5 • --enable-cldw-sy6 • --enable-sas: SAS • --enable-ccmcnv: NCAR CCM3 Zhang McFarlane convection • --enable-baseout: post processed basefield output (r_bpgb.ftxx)

  6. CVS system • cvs co [module_name] • cvs update [file_name] • cvs diff [file_name] • cvs log [file_name] • You can use options such as –r (version), -date

  7. Model System • libs : library, utilities, independent of model resolution but machine dependent • rsm (or crsm): source codes and binaries, model resolution dependent e.g., rsm/def/rsm6228r5455 • runs: run scripts runs/runscr: run scripts called by rsm/rsim/csim runs/expscr: templates for rsm/rsim/csim

  8. Building the model without installer • In libs, $ configure-libs • In rsm You can edit rsm/def/physics.h, misc.h, debug.h, diag.h to change model options such as KF2 (Kain Fritsch convection) that is not supported by --enable-xxx with installer script. $ configure-model • In runs, $ configure-scr [rsm/rsim/csim]

  9. Other things to note… • Set stacksize to unlimited, otherwise rmtn.x fails.

  10. Regional Domain • rsm/def/rsm6228r5455 • igrd, jgrd, cigrd, cjgrd Igrd has to be a product of integer powers of 2, 3, and 5. On IBM, integer power for 3 cannot be more than 2. jgrd has to be an odd number. cigrd and jgrd are coarse resolution regional file paramters for crsm. • Parameters RPROJ, RTRUTH, RORIENT, RDELX, RDELY, RCENLAT, RCENLON, RLFTGRD, RBTMGRD • Use libs/etc/prmap to choose a domain.

  11. Utility Programs in libs/etc • date: returns date of sigma and surface files • fhour: • force_date_grib: change the date in grib files (r_pgb.ftxx) • grmap: creates ctl file for GrADs from r_pgb.ftxx • grmean: creates average of r_pgb.ftxx • incdte: • inchour: • jd: returns julian day from • prmap: used for choosing the domain. reads igrd and jgrd in rsm/define.h and domain paramters in rsm/rsim script and creates prmap.ctl which is opened in GrADs for display.

  12. Input Files (for RSM) • Available global files from the data server at ECPC 6-hourly R1 (NCEP/NCAR Reanalysis): r1/ directory 6-hourly R2 (NCEP/DOE Reanalysis): r2/ directory daily sst.grib: sfcanl/ directory daily ice.grib: sfcanl/ directory • sftp dataman@tsuzumi.ucsd.edu (password: data_ecpc)

  13. Input Files (for CRSM) • Available coarser resolution regional files from ecpc.ucsd.edu (Jack Richie): • Customized sub-domain data from GSM forecasts initialized by NCEP daily operational analysis • Create a binary r_sig files and then use scnvrt and r_inpg to interpolate them to the target regional grid

  14. Other Input Files • Not supported, but it should not be too difficult: ERA-40 Reanalysis, NCEP daily operational analysis • libs/etc/scnvrt: • runs/runscr/r_inpg: interpolation (both horizontal and vertical)

  15. Experiments • RSM (use networked machine): use R1 files as boundary conditions; run rsm script for testing; run rsim script for 2002 Nov 1st to 3rd by downloading files from ECPC. • CRSM (use non-networked machine): use Jack’s GSM output (L18) over Vietnam; run csim script at L18 for 2006 July 1st to 3rd • If time allows – run RSM with rsim script for 2002 Nov 1st to 3rd over Vietnam and run CRSM with the output and csim script
