4.1.2 Isosurfaces of Gridded Data
While plan views of 3D fields are useful, the three dimensionality of the atmosphere can be displayed in the IDV using isosurfaces. An isosurface represents a 3-D surface that connects points with the same value. On one side of the surface, values are greater than the surface value; on the other side, values are less than the surface value.
  1. Create an isosurface of wind speed showing areas of winds 40 m/s or greater.
  2. You can also create isosurfaces of one variable that is colored by another variable. In this step, you will load in an isosurface of wind speed again, but this time you will have it colored by geopotential height.
  3. You can modify the colors the display through the menus in the control window or legend.
