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 25 U.S. stations (Blocks 72 and 74) were cited at least
once; 8 were cited at least twice; and 3 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
                    72250/BRO                  20       20
                    72451/DDC                   9        9

Ground equipment failures were reported by WFO BRO from the 3rd through the
13th and again on the 17th.  WFO DDC reported ground equipment failures from
the 1st through the 5th.

(2)  Reports from 38 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 21 were cited at least twice; and 13 were cited at least three

Flight equipment failures occurred throughout the month at stations MZT, LAP,
HYY, and MZL.  Ground equipment failures occurred throughout the month at YAK
and CUR and from the 19th through the 25th at SNP.  In addition, ascents were
not authorized at YAK and CUR sporadically throughout the month.  Finally,
manual deletions at MID and LIH were for 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.
