Monthly Raob Data Manual QC Report for Feb. 2021

Previous Monthly Raob Data Reports of Manual Quality Control

SUBJECT:        Monthly Raob Data Report of Manual Quality Control


The Raob Report for February, 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 31 U.S. stations (Blocks 72 and 74) were cited at least
once; 19 were cited at least twice; and 7 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
                    72694/SLE   3               9       12
                    72202/MFL   5                        5
                    72357/OUN   3               2        5
                    72747/INL   3                   2    5
                    72214/TAE   3               1        4
                    72249/FWD   3               1        4

Station SLE reported ground equipment failures throughout the month, and station
OUN reported one ground equipment failure and one flight equipment failure in
February.  While all deletions at stations TAE and FWD were due to super-adiabatic
lapse rates, there was a wide variety of reasons for deletions at stations MFL,
OUN, and INL.  Those reasons included super-adiabatic lapse rates, but also
included height issues, one instance of strong winds, and spurious data
throughout the column.

(2)  Reports from 41 stations in blocks 04, 70, 71, 76, 78 and 91 were cited
at least once; 20 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:

                    STATION__ DEL BAS COR XRP EFL SHO TOTAL
                    78073/NAS                  29       29

                    70308/SNP                   7   2    9
                    91348/PNI   8                        8
                    70361/YAK   1               5        6
                    78397/KIN   4   1           1        6
                    76394/MTY   4                        4

Stations NAS, MAJ, TKK, SNP, and KIN reported several ground equipment failures in
February.  Station LAP reported several flight equipment failures in February, and
station YAK reported one flight equipment failure, but the rest of the failures were
ground equipment failures.  Most manual deletions throughout the month were due to
super-adiabatic lapse rates.  However, at station MTY, all manual deletions were due 
to high heights throughout the column.  

* 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.
