Conclusions
The 2000 STEPS results identify a storm with strong VHF
emissions and no recorded VLF triggers, reflecting cases with FORTE
RF events without coincident NLDN VLF events. Closer examination of
the storm is underway. The Florida/KSC results show: 1. the height
distribution of the closest temporal LDAR VHF source vs LASA VLF/LF
Narrow Bipolar source is reasonably consistent with earlier
EDOT/FORTE comparisons of height; 2. Work remains to understand the
exact VLF/LF emission source and the VHF emissions recorded by
LDAR.
