           SUBJECT:        Monthly Raob Data Report of Manual Quality Control


The Raob Report for November, 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 19 U.S. stations (Blocks 72 and 74) were cited at least
once; 8 were cited at least twice; and 4 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
                    72235/JAN   4                        4
                    72562/LBF                   4        4
                    72251/CRP   1               3        4

Two of the manual deletions of JAN were for wet bulb effect.  Both of those 
deletions were on the 16th, one during the 00Z cycle and one during the 12Z
cycle.  The other two deletions were for spurious winds at the surface.  CRP
reported ground equipment failures starting at 12Z on the 10th through 12Z on
the 11th, and LBF reported ground equipment failures for all cycles on the 19th 
and 20th of the month.

(2)  Reports from 41 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 24 were cited at least twice; and 19 were cited at least three
times.  Of those, the following were cited more than three times or had two or
more no reports:

                    91765/PPG   4                        4

Most manual deletions for TKK and PPG were for temps and RH due to wet bulb
effect.  In addition, MZL had some temp, RH, and height deletions due to
super adiabatic lapse rates and warm temperatures.  Manual deletions for GCM,
however, were for winds that were too strong.  As far as equipment failures,
almost all equipment failures were flight and ground equipment failures.  GYM
reported flight equipment failures for most 12Z cycles throughout November, and
CUU reported flight equipment failures for most 12Z cycles starting on the 19th
of the month.  Ground equipment failures were reported by SXM throughout the 
month and by GDL in the latter half of the month.  AKN reported ground equipment 
failures starting at 00Z on the 2nd through 00Z on the 5th, and CUR reported 
ground equipment failures for all 12Z cycles from the 15th through the 17th.

* 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.
