Welcome back to AWIPS Tips!
This week we are going to look at how to customize contours for products in CAVE by changing the styleRules. Customizations include adjusting the color, line type, smoothing, interval, and range by creating a user override of the d2dContourStyleRules.xml file. Below we will walk through the different options and show an example of a customized contour for model surface temperatures. By default, if you load Models > GFS 20km > Sfc Temperature and Wind and you turn off all product layers except the contoured Surface Temperature, you can see it’s a pretty bland display, but we can customize it to look much more useful!

Once you’ve made your changes and have saved your updates, switch back to the D2D perspective, clear the map in CAVE, and reload the product: Models > GFS 20km > Sfc Temperature and Wind (turn off the other layers), and you will see your customized styleRules for surface temperature!
The Warning Decision Training Division has a job sheet that walks through another example for customizing wind contours and an example on using the value tag for fixed labels.
