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 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 29 U.S. stations (Blocks 72 and 74) were cited at least
once; 11 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
                    72357/OUN                   6        6
                    72662/UNR                   2   2    4

OUN reported ground equipment failures on the 4th and 5th of August, as well as
the 13th and 14th of the month.

(2)  Reports from 35 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 18 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
                    76256/GYM   2   1          11       13*

                    78384/GCM                   4        4

GYM reported numerous flight equipment failures in August, and GCM reported a
few ground equipment failures between the 8th and the 13th of the month.
Stations LAP, MEX, MZT, and MZL all had several incidences of height and 
temperature anomalies leading to widespread height, temperature, and moisture
deletions.  Manual deletions for PPG were for temperatures and moisture due to
super-adiabatic lapse rates.  Finally, erratic winds were a common issue at
station SXM in August.

* 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.
