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 January, 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 24 U.S. stations (Blocks 72 and 74) were cited at least
once; 9 were cited at least twice; and 2 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
                    72214/TAE   3               1   1    4*

All deletions for TAE were for temperatures and moisture due to super-adiabatic
lapse rates.

(2)  Reports from 35 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 20 were cited at least twice; and 16 were cited at least three
times.  Of those, the following were cited more than three times or had two or
more no reports:

Flight equipment failures were reported throughout the month from the following
stations: HYY, CUU, MZT, GYM, and ACA.  Meanwhile, ground equipment failures
were reported from SXM.  PNI also reported ground equipment failures from the
1st through the 6th.  Finally, SYA reported a variety of equipment issues 
including power failures, unfavorable weather conditions, and flight equipment
failures.

Temperatures and moisture were manually deleted for stations GYM, ADQ, and BDA
due to super-adiabatic lapse rates.  Finally, heights and temperatures were
manually deleted at stations MZL, MEX, and LAP due to high/low heights and
warm/cold 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.
