Retrieving high resolution nested grid data:
Choose c1a (not ecgate) upon login to access the supercomputer facility (HPCE)
Copy the following directory and files to your home directory on HPCE:
flex_extract_ecgate_V4
List of files:
flex_ecmwf_91_finegrid_* extract_ecmwf_ftpbase seq_extract.V4* seq_control.V4* submit*
1. Edit the times in the file: seq_control.V4* ./seq_extract.V4 1990 1990 06 06 29 29 1
2. In file flex_ecmwf_91_finegrid_* modify the following parameters:
M_GRID 20 (resolution 0.2 deg, for resolution of e.g. 10 deg use 1000)
M_LEFT -3600 (36 W)
M_LOWER 4000 (40 N)
M_UPPER 7600 (76 N)
M_RIGHT 3600 (36 E)
M_FORMAT GRIB2 (GRIB1 or GRIB2)
DESTINATION nina (or another MS association set up on the web interface, e.g flexpart)
ECFSDIR ectmp:/${USER}/GRIM/ (directory name)
SOURCECODE /home/ms/no/sb9/flex_extract_ecgate_V4 (your username)
Notice: M_GRID/90 must be a whole number
M_LOWER/M_GRID must be a whole number, same with the three other coordinates
(M_UPPER-M_LOWER) / M_GRID must equal a whole number
(M_LEFT-M_RIGHT) / M_GRID must equal a whole number
3. Change all paths to refer to your own user
grep sb9 *
to list all files containing the path with user sb9 which need to be changed.
4. Copy the template file flex_ecmwf_91_finegrid_* to extract_ecmwf_ftpbase
5. Run the job:
./submit
6. Check your job:
llq to see your job in the queue
eoj <jobid> provides details on the performance of a running job. (also automatically provided at end of job)
7. Get your files:
The retrieved files are automatically transferred to your ecgate account (via ECTRANS) and then to NILU by ftp. (NB: cannot ftp directly from HPCE, but must go via ecgate). If you can’t find your files in your defined NILU-directory, check the directory you specified in flex_ecmwf_91_finegrid_* (ECFSDIR) for where it is temporarily stored on the ECWMF system. Then try ftp it over again using the ftp commands specified previously.
