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 33 U.S. stations (Blocks 72 and 74) were cited at least
once; 18 were cited at least twice; and 10 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

                    72764/BIS                   4        4

Ground equipment failures were reported at station LCH from the 26th through
the 30th, station CRP from the 25th through the 28th, and station BIS from the
30th through the 31st.  All manual deletions at stations MFL and JAN were for
temperatures and moisture due to super-adiabatic lapse rates.

(2)  Reports from 50 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 30 were cited at least twice; and 20 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 at stations LAP, MZL, HYY, MZT, MID,
CUU, GYM, and ACA.  Ground equipment failures were reported by station NAS
throughout the month.  Ground equipment failures were reported at station FAI
during the first half of the month and at stations MCG and GCM during the
second half of the month.  At station, YJT most manual deletions were for 
high temperatures.  Meanwhile, the vast majority of manual deletions at
stations PNI, BGI, YAP, YYE, and LIH were for temperatures and moisture due to
super-adiabatic lapse rates.

* 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.
