SUBJECT:        Monthly Raob Data Report of Manual Quality Control


The Raob Report for June, 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 34 U.S. stations (Blocks 72 and 74) were cited at least
once; 15 were cited at least twice; and 5 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
                    72230/BMX                   3   3    6
                    72210/TBW   1               1   3    5
                    72456/TOP   3                   2    4*

Two out of the three manual deletions at TOP and the only manual deletion at
TBW were for temperatures and moisture due to super-adiabatic lapse rates.

(2)  Reports from 42 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 22 were cited at least twice; and 14 were cited at least three
times.  Of those, the following were cited more than three times or had two or
more no reports:

With respect to equipment failures, MZL, HYY, GYM, and MID reported flight
equipment failures during June.  MZL and HYY reported them all through the
month, while GYM reported them during the latter half of the month, and MID
reported them during the first half of the month.  Meanwhile, BET, ACA, MCG,
and OME reported ground equipment failures in June.  BET's were isolated to the
9th through the 14th.  MCG's were from the 23rd through the 28th.  OME reported
them on the 13th, as well as the 18th through the 21st.  ACA reported ground
equipment failures throughout the latter half of the month.  All manual
deletions at all of the above listed stations in June were for temperatures and
moisture due to super-adiabatic lapse rates.  Finally, station SYA's reports 
were missing TTBB significant level data throughout the month of June.

* 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.
