SUBJECT:        Monthly Raob Data Report of Manual Quality Control


The Raob Report for July, 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 35 U.S. stations (Blocks 72 and 74) were cited at least
once; 17 were cited at least twice; and 4 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
                    72797/UIL                   5        5

                    72582/LKN   3                   1    4

Station UIL reported ground equipment failures from the 7th through the 9th
of July.  At stations DNR and LKN, all manual deletions were due to super-
adiabatic lapse rates.

(2)  Reports from 47 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 30 were cited at least twice; and 23 were cited at least three
times.  Of those, the following were cited more than three times or had two or
more no reports:

Ground equipment failures were reported at various times throughout the month
at stations GCM, BRW, TKK, SNP, PNI, MCG, and OME.  Station LAP reported flight
equipment failures in the early part of the month.  At stations, WSE, YQD, YEU, and
GYM, all deletions were due to super-adiabatic lapse rates.  On the other hand,
stations MTY, YBK, GDL, and YLT, deletions were due to issues with heights and
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.
