Run ripdp

Create a directory to save the post-processed data to:
        mkdir RIPDP

Now run ripdp to post-process the data. We want all the data - so no need to use the ripdp namelist.

    ./ripdp_wrfarw  RIPDP/myCase  all  ../WRFV3/test/em_real/wrfout_d01_
 

NOTE: Use ripdp_wrfarw for WRF-ARW core, and ripd_wrfnmm for WRF-NMM core.

TIP: The use of the ripdp namelist is optional for WRF-ARW.
       It is also optional for WRF-NMM if you are not redefining the grid (iinterp=0)

Sample ripdp namelist specific to:
WRF-ARW core	WRF-NMM core
ripdp_wrfarw_sample.in	ripdp_wrfnmm_boston_d01.in ripdp_wrfnmm_boston_d02.in ripdp_wrfnmm_katrina_d01.in ripdp_wrfnmm_katrina_d02.in ripdp_wrfnmm_sample.in

Run rip

Copy a namelist to your working directory:
   cp sample_infiles/rip_sample.in .

There are a number of sample files available for the different cores and for ARW idealized cases:

Sample rip namelist specific to:
WRF-ARW & WRF-NMM cores (real cases)	WRF-ARW core (ideal cases)	WRF-NMM core
rip_sample.in	bwave.in grav2d_x.in hill2d.in qss.in sqx.in sqy.in	rip_boston_d01.in rip_boston_d02.in rip_katrina_d01.in rip_katrina_d02.in

 

Edit this namelist. Pay attention to the following:

• ptimes
  Make sure these correspond to the available times in your wrfout file
  e.g., 0,-12,3  means hours 0 to 12 every 3 hours. This can also be specified as 0,3,6,9,12
   
• ncarg_type
  Use this to control the output type. Available options are 'cgm', 'x11', 'pdf'
   
• Look for the line: feld=tic; ptyp=sb; sloc=KORD; hodo; sndg
  The function of this line is to generate a skewT plot at location KORD (which is the Chicago-O'Hare International Airport).
  For our case study domain, this will be outside the domain. Using this will create the following error message
       The sounding requested at the following
       location is outside the cross-point domain:
       x,y=     ,     lat,lon= 41.98, -87.90 stn=KORD,72530
       Please correct input file and re-execute RIP
  
  To solve this problem, change the station location to a location inside your domain. Example, sloc=KBOU, is a station in Boulder, Colorado.
  A full list of station names are available in the stationlist file located in the RIP4 directory.
  

Run rip
   ./rip  -f  RIPDP/myCase  rip_sample.in

Depending on the setting of ncarg_type in the namelist, the output will either be displayed on your screen ('x11'), or written to rip_sample.cgm ('cgm') / rip_sample.pdf ('pdf')

To display cgm files, make use of the NCAR Graphics command 'idt', e.g.,

idt rip_sample.cgm
