Create a Time Series

We want to create a time series for grid point (55,40). In order to do this we need to create a file tserstn.dat in our RIP working directory.
Create one, or copy the above linked file.

We are interested in the value of slp over time at this point. So we create an slp.in file. Note the addition of the parameter idotser=1 in this file.

Run rip

./rip -f RIPDP/katrina slp.in

This will create a file slp.tser, containing the time series information at this point.

---

Let's get creative

Generate time series for slp, temperature, dbz at the surface and dbz at pressure levels 1000 to 200 hPa.

First we need UIF files for all 4 of these (we could just use one UIF for all 4, but we want to use the data creatively later, so let's use 4)

• slp.in
• tc.in
• dbz.in
• dbz_levs.in
  

Run rip for all 4 of these. This will generate 4 output files: slp.tser, tc.tser, dbz.tser and dbz_levs.tser.

Edit these 4 files and remove all lines that do not contain data. When you are done, the files will look like this: slp.tser, tc.tser, dbz.tser and dbz_levs.tser.

We can now use these 4 files as input to an NCL script (plot_tc.ncl*) to create a plot that looks like this:

*Note: This is just a sample script of what you can do with RIP output. For information on creating your own creative plots, please see the NCL web pages.
