SUBJECT:        Monthly Raob Data Report of Manual Quality Control


The Raob Report for August, 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 30 U.S. stations (Blocks 72 and 74) were cited at least
once; 13 were cited at least twice; and 6 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
                    72318/RNK   4                   1    5
                    72528/BUF                   5        5
                    72208/CHS   1               3        4
                    72363/AMA   3                   1    4
                    72456/TOP   3                   1    4

Manual deletions of temperatures and moisture at stations RNK and AMA were due
to super-adiabatic lapse rates.  While one of the deletions at TOP was due to
super-adiabatic lapse rates, the other two deletions at that site were only
heights due to high heights.  Ground equipment failures were reported by BUF
from the 23rd through the 25th and by CHS on the 10th and 11th.

(2)  Reports from 46 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 25 were cited at least twice; and 14 were cited at least three
times.  Of those, the following were cited more than three times or had two or
more no reports:

                    91285/ITO   4                        4

Manual deletions of temperatures and moisture at stations PPG and ITO were due
to super-adiabatic lapse rates.  Heights were deleted at station CUR a few
times due to high heights.  Station SYA had numerous incidences of missing Part
TTBB.  Most of these were during the 12Z cycles.  Flight equipment failures
were reported by MZL, HYY, GYM, and LAP throughout the month.  At HYY and LAP,
these were mostly at the 00Z cycles, and at GYM, these were at the 12Z cycles.
Finally, ground equipment failures were reported all month at station NAS.

* 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.
