Latest Monthly Raob Data Report of Manual Quality Control

Previous Monthly Raob Data Reports of Manual Quality Control

SUBJECT:        Monthly Raob Data Report of Manual Quality Control


The Raob Report for October, compiled from the Raob Recap statements in the
SDM logs, which does not necessarily include data that were rejected by
automated computer generated quality control, indicates the following:

(1)  Reports from 37 U.S. stations (Blocks 72 and 74) were cited at least
once; 17 were cited at least twice; and 11 were cited at least three times.
Of those, the following were cited more than three times or had two or more no
reports:

                    STATION__ DEL BAS COR XRP EFL SHO TOTAL
                    72250/BRO   1               8        9
                    72393/VBG   5                        5
                    72469/DNR   4                   1    5
                    74455/DVN   3                   1    4

BRO reported ground equipment failures from the 1st through the 4th of October.
All but two of the manual deletions throughout the month were for temperatures
and moisture due to super-adiabatic lapse rates.

(2)  Reports from 37 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 17 were cited at least twice; and 13 were cited at least three
times.  Of those, the following were cited more than three times or had two or
more no reports:

                    STATION__ DEL BAS COR XRP EFL SHO TOTAL
                    76692/HYY                  55       55

                    91765/PPG   4                        4

Flight equipment failures were reported at stations HYY, LAP, MID, and GYM
throughout the month of October. The vast majority of equipment failures at
stations MZL, ACA, and MZT were also flight equipment failures, but one or two
equipment failures at each of those stations were ground equipment failures.
NAS reported ground equipment failures from the 20th through the 31st of
October.  Finally, manual deletions at PPG and one of the YCB deletions were
due to super-adiabatic lapse rates, and the other two manual deletions at YCB 
were due to high temperatures.

* 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.
