Station NAS reported ground equipment failures throughout the month.  A handful of
ground equipment failures were also reported by stations SNP and YAP.  Stations
LAP and MZL reported numerous flight equipment failures throughout April.  Manual
deletions at stations LIH and PNI were for temperatures and moisture due to
super-adiabatic lapse rates.  Finally, station MTY purged all heights on several
occasions due to high heights, and YEU purged all heights several times due to 
low heights. 

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.
