Choices of numbers of stations, background maps, map projection, wind barb size, and vertical interval can make Profiler displays which range from very sparse to very complex. Work with just the data you want to see and try different choices to bring out the best of the Profiler data.
1. Use Data Projection
• Click on the View→Use Data Projection menu item in the control window.
• The display is remapped to show the data in its native data projection. This is very useful for Profiler plots if your previous projection was not suitable for showing the data. For example, if you were looking at model output over North America before you looked at Profiler, and the menu item Projections→Auto-set Projection was not checked on, the Profiler display is very small.
2. Merging Data
• Make a 3D View of Profiler winds from a few stations, in its own projection.
• Click off the menu item Projections→Auto-set Projection, so other data put in this display does not alter the projection.
• Select a data source of model output, for the same time and area.
• Make a display from the model analysis of wind barbs at upper air levels.
• Use time animation, and viewpoint rotation, to compare the wind data from two sources.
