SYNTHESIS FOR JUNE 24, 2000 - ABFM

Investigator: None
[Not presented at a teleconference.]

The following summary is from the notes that Jim Dye and Eric Defer put together. Probably early in 2001 (before the May/June 2001 Field Campaign).

 

 

 

E fields reported in the summaries below are based on the old matrix for determination of the three components of the field. The new matrix provided in April 2001 reduces the negative values of Ez as much as 40 to 60%. So the values reported herein may be too large. Positions are reported herein as (X,Y) coordinates relative to the WSR74-C radar.

Th total concentrations of particles measured by the 2D-C probe are denoted as N30 (ie. concentration of particles >30 microns which is heavily weighted towards smaller particles). N1 refers to the concentration of particles >1mm size, ie. the larger particles. Radar plots were available for only a few of the last summaries we prepared (June 4, 6, and 11). For other days some of the realtime radar plots were utilized but need to be verified.

 

June 24

Flight 1 from 1636 to 1957 in decaying anvils over KSC. Spirals were flown over the SLF and east.

Flight 2 from 2059 to 2342 in debris and decaying anvils over KSC.
