SDM logs, which does not necessarily include data that were rejected by
automated computer generated quality control, indicates the following:
(1) Reports from 21 U.S. stations (Blocks 72 and 74) were cited at least

STATION__ DEL BAS COR XRP EFL SHO TOTAL
72340/LZK 59 59
Station LZK reported ground equipment failures throughout March.
(2) Reports from 23 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 11 were cited at least twice; and 8 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
70200/OME 32 32
70316/CDB 29 29
70326/AKN 10 10
70414/SYA 7 7
70026/BRW 5 5
Station SYA reported several flight equipment failures in the first half of March,
and station OME reported flight equipment failures throughout the whole month.
Stations AKN and BRW reported several ground equipment failures during the latter
part of March. Station CDB also reported ground equipment failures throughout the
month, along with several power failures during the first half of March.
* 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.

The Monthly Raob Data Report of Manual Quality Control is issued as soon as possible after the end of each calendar month. The report is the
result of a compilation of entries in the Senior Duty Meteorologist (SDM) daily logs during the specified calendar month with emphasis on entries
pertaining to data which were flagged for deletion. Raob stations in the North American regions which were most problematic will stand out in this
report.
The report divides the North American region (raob blocks 04, 70, 71, 72, 74, 76, 78, and also U.S. supported block 91 stations which include
Hawaii and Pacific Island U.S.A. possessions) into two divisions. The first comprises the CONUS U.S.A. (blocks 72 and 74), and the second
comprises all others (blocks 04, 70, 71, 76, 78, and 91). For both divisions, the report provides general quantitative information followed by a
specific list of stations that had more than three citations during the month. Also, the author will render statements pertaining to trends or
possible explanations for the more problematic stations.
