Overview

  • Track circles with the tool to create time trend of radar, satellite, grid image, and total lightning density
    • Does not work with contours, wind barbs, station plots
  • Apply 8 math operators (max, min, sum, mean, median, standard deviation, range difference, and amplitude)
    • Range difference: absolute value of max difference (good for rotation and divergence delta Vs in radar)
    • Amplitude: max absolue value (good for damaging wind in base velocity data)
  • Tracking Meteogram draws a 100x100 grid box and samples the raw data (before AWIPS 16.1.2, 20x20 grid box and sampled pixels drawn on screen)

Refresher Commands

  • Loading - select Tracking Meteogram Tool from Tools menu
  • Change Circle Size - scroll wheel while mouse pointer is on circle
  • Configure Meteogram - right click on circle to launch configuration menu
  • Configure trend graph properties - right click on time trend 

Usage Tips

  • Avoid having circles extend outside of data domains (grid domains for high-res models in particular) as they can corrupt your calculations.

Limitations

  • Breaks keyboard shortcuts like Del key on keypad for toggling radar
    • Workaround: click on time trend plot then click back on map editor to restore keyboard shortcuts
  • Does not work with All-Tilts
  • Cannot save in procedures and cannot save plot configuration changes
