Assessment of PowerPoint Slide Count for Looping through Time: Radar Reflectivity, CI Points, and General Conclusions

This assessment highlights the tremendous slide count in PowerPoint, but focuses on radar reflectivity, CI points, and general conclusions. It mentions problems with storm cycling, the 15km exclusion zone, and the CIv2 threshold. It also emphasizes the need for ice cloud masked stats and assessing imagery with algorithm CI nowcasts.

  1. UW/CIMSS CI Assessment Description of Powerpoint Slide count is tremendous, but that is for simply quickly looping through time - Three subsets are presented in the following order: radar reflectivity @ -10C CI Points CIv2 Points radar reflectivity @ -10C with human CI points summary for region General Conclusions Storm cycling results in too many points 15km exclusion zone may not be working? (shown on slide 47, but can be seen in many others) 13km^2 CIv2 threshold does not seem to be working; very small spots on those graphics (shown on slide 81, but can be seen in many others) Regardless of how CI points are defined, ice cloud masked set of stats should be produced (total, day, and night) Still need to assess imagery with algorithm CI nowcasts; with hits and false alarms distinguished atop reflectivity at -10C to determine accuracy of tracking regardless of CI definition.

  2. Radar - North Carolina 1621 - 1856 UTC

  3. CI Points

  4. 15 km threshold does not seem to be applied here – 3 CI points
