Welcome back to AWIPS Tips! This week we are looking into creating an objective analysis plot in CAVE by loading both model data and current observations. The display/time options are a bit tricky to set up initially, but once you’ve created the plot, you can save it as a display to easily reload it.
Before we load our first product, let’s configure the Display and Time properties. Select Options > Display Properties and change the Load Mode to Forecast match. Then toggle on Options > Time Options.
Next we’re going to load some model data. Open the Volume Browser (Models > Volume Browser) and select the following:
- Display Type: Plan view
- Loop Type: Time
- Sources: RAP13
- Fields:
- Hgt/Pressure > Height
- Wind > Wind (Total)
- Vorticity > (Absolute Vorticity)
- Planes: Pres > 500mb
Select Load and a window will appear with a list of valid times. Scroll through to find the latest forecast run at the 0HR and select OK.
TIP: If you are having trouble finding the time, select a Valid Time and start typing the time you are looking for.
If you scroll back and forth in time, you will notice the 0HR forecast is plotted for the previous X number of runs (instead of normally getting each forecast hour from the latest run).
Next, you can load a satellite product, for example the Satellite > GOES-East CONUS > Mid-level Water Vapor IR Band (Ch 9).
By hold-right-clicking on the product in the Resource Stack, you can modify the density, colors, line types, etc. to configure your plot to your liking. See a demo of this here.
Once you have your plot the way you like it, you can save it as a procedure or display to easily bring it up in the future!
Check back in two weeks for the next blog post, where we will explore using the WarnGen tool.
