SUBJECT:        Monthly Raob Data Report of Manual Quality Control


The Raob Report for December, 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; 20 were cited at least twice; and 11 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
                    72476/GJT                   8        8
                    72206/JAX                   6        6

                    72318/RNK   3                   1    4

All equipment failures at GJT, JAX, and BMX were ground equipment failures. GJT
reported ground equipment failures on the 3rd and 4th and the 29th through 31st.
JAX reported these failures on the 25th through 28th, and BMX reported them on
the 28th and 29th.  All deletions were due to wet bulb effects.

(2)  Reports from 36 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 19 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 LAP reported flight equipment failures from the 1st through 4th of 
December.   Station YAK reported a mixutre of power failures and ground
equipment failures throughout the month.  All other equipment failures at all
other stations throughout the month were ground equipment failures.  At station
MTY, there were numerous manual deletions of heights and temperatures due to
high heights.  All other manual deletions at other stations were 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.
