RIP

1
RIP

• A tool to create plots from WRF model output

2
RIP(Read, Interpolate, Plot)

• Developed over many years by Mark Stoelinga of
  the University of Washington
• Not a gui-driven visualization tool. To use rip,
  you edit a configuration file and run the rip
  executable, then view the static images created
  by rip
• Allows user fine control over nearly all aspects
  of the plot easy to make publication-quality
  graphics (once you get a feel for the arcane
  commands)
• Not so great as a quick-look tool

3
RIP capabilities include

• Cross-sections on various types of
  quasi-horizontal surfaces
• model sigma, pressure, height, isentropic, etc.
• Vertical cross-sections along arbitrary lines
• Vertical profiles and skew-T diagrams
• Contours, vectors, barbs, color-fill, maps,
  labels, etc., and almost any combination thereof
• Difference fields between two model jobs

4
For the colloquium case studies

• Input datasets for RIP have been created for you
  
• i.e., you can skip the ripdp step
• Sub-sampled and windowed for easier plotting on
  the classroom machines
• Selected forecast hours to keep disk usage under
  control
• Sample configuration files have been created for
  you
• to give you a starting point for creating your
  own configuration files
• Plot files of many useful fields have been
  created for you
• lots of images are available for you to peruse
  before you even run RIP
• Images on the full model grid, not sub-sampled or
  windowed
• Images at hourly time interval

5
To use RIP

• 1) Prepare the data
• Largely done for you
• 2) Prepare the instruction file
• This is the hard part. We offer some samples to
  get you started
• 3) Run the program
• 4) View the results
• idt command

RIP suggestions

• Bookmark the online documentation and refer to it
  often
• Beware of commas and semicolons, and avoid blank
  lines
• Dont plot too much at once
• It can take a long time, and you just end up
  waiting
• Dont spend too much time getting a plot to look
  just right
• Some keyword settings are remembered from frame
  to frame. Some are forgotten.
