                    91165/LIH   4                        4

Numerous flight equipment failures were reported by stations MZL, MZT, HYY, and
GYM, while ground equipment failures were reported by stations BET and CUR.
Reports from SYA were frequently missing Part TTBB.  As far as manual deletions
heights and temperatures were purged from LAP a few times due to high heights
and warm temperatures.  Finally, LIH had a few incidences of the wet bulb
effect requiring deletions of temperatures and moisture. 

* The total differs from the sum of the itemized citations
  because of multiple citations in the same raob(s).


Citation Codes Key:
DEL  All or part of the raob was flagged for deletion.
BAS  A baseline hgt/station press error was corrected or purged.
COR  At least one correction other than baseline was made.
XRP  Station sent no report at all when one was required.
EFL  Equipment failure (codes 10142, 10144, 10158, etc.)
SHO  Raob flight was short; ie, to less than 400 mb.
