Testing CRSM (C2R) Part II


In this experiment, we will use GSM forecast subdomain output created by Jack Ritchie at ECPC.

EXPERIMENT

  • 25x21 coarse resolution (190km) output in ascii over Southeast Asia
  • 2006 July 1st 00Z to 3rd 00Z for 48 hours
  • Target domain: 36x35 (60km)
  • 18 vertical levels. No vertical interpolation

INSTRUCTIONS

  • Download data, scripts, and code
    • If you have an access to ecpc.ucsd.edu, Go to /pub/drf/vietplus/fcst_2006070100 and download s_r_sigG.f0000.asc.gz to s_r_sigG.f0048.asc.gz (every 6hours) and r_sfcG.f0000.asc.gz. Gunzip the data. Also,go to /pub/drf/vietplus/sppt and download the files (for data conversion) in the directory.
    • If you do not have an access to ecpc.ucsd.edu, download this tar file of input files. The tar file has all sigma and surface files you need for the experiment. Also, download this tar file for scripts and code for data conversion. (If you want to start using the server, ecpc.ucsd.edu, e-mail Jack Ritchie at jack@annalisa.ucsd.edu with your IP address).
    • Download sst.grib and ice.grib for 2006 from ECPC data server.
  • Convert input data
    • r_a2d18L converts ascii sigma file to binary. r_a2dsfc converts ascii surface file to binary. You might need to edit the scripts and code for your system and compiler. See this tar file , if you downloaded files from ecpcp.ucsd.edu in the previous step, for your reference. Use "pgf90 -r8 -byteswapio" to compile the Fotrtran conversion codes.
    • Convert s_r_sigG.f00$hour.asc to r_sig.ft$hour
    • Convert r_sfcG.f0000.asc to r_sfc.ft00
  • Install CRSM by typing INSTALL and selecting crsm as model.
  • Choose ecpc if your institution is not listed
  • Choose 6218r2521c3635 (downscale 25x21 to 36x35, 18 levels)
  • Go to runs/expscr and edit csim.in
