SUBJECT:        Monthly Raob Data Report of Manual Quality Control


The Raob Report for December, 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 29 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
                    72562/LBF                   8        8
                    72402/WAL   4                   1    5
                    72249/FWD   4                        4

LBF had 8 reports of ground equipment failures in December, from 12/8 to
12/12 with the rest of the month clean.  WAL had four deletions due to
moisture issues, while FWD had three deletions due to moisture and one
due to height/temp issues.

(2)  Reports from 38 stations in blocks 04, 70, 71, 76, 78 and 91 were
cited at least once; 19 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:

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

Stations MID, BDA and PNI all had three deletions due to moisture issues,
with MID having an additional temp/height issue.  GYM and LAP had mainly
flight equipment failures throughout the month.  MZL had a variety of
issues with deletions and failures.  CURs failures were all of the
ground equipment issue variety.  CUN had three deletions due to moisture,
and one wind related.  HYY had the inverse, three deletions due to
hgts/temps and one moisture related. 


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.
