OFFICE NOTE 29
(Updated version of September 1973 edition)
NMC/NCEP FORMAT FOR OBSERVATIONAL DATA
(UPPER-AIR, SINGLE-LEVEL, CLOUD COVER, ADDITIONAL REPORTS)
Original

September 1973
FINAL Revision
Dennis A. Keyser
NCEP Environmental Modeling Center
MARCH 2001
Revision Number 5 to NMC/NCEP Office Note Number 29.
The date of this revision is March 12, 2001 (03/12/2001).
This revision represents the final update
to NMC/NCEP Office
Note Number 29. This format for
representing meteorological
observational data at NMC (later NCEP)
was discontinued in March
1997 when WMO FM 94-IX Code Form: Binary
Universal Format for
the Representation of meteorological data
(BUFR)
became
operational at NCEP. WMO BUFR remains
the official
observational data format at NCEP.
An accurate version of this
Office Note is still necessary for historical
reference. This
revision incorporates corrections and
expansions of various
tables specifying report type, instrument
type and additional
data code figures for certain meteorological
parameters which
were previously unspecified.
Revision Number 4 (dated 2/16/1996) had
also incorporated
corrections and expansions of these tables
as well as quality
mark tables and reserve characters.
In addition, Revision
Number 4 removed two categories (51 and
52) since they pertained
to surface reports and are found in NMC/NCEP
Office Note Number
124.
Other Revision 4 changes:
1) The previous
Table R.2 (Instrument Type) was split into
two tables. Table
R.2a lists the instrument type designators in
effect prior to 1200 UTC 1/22/92.
Effective on this date, the
instrument type designators in both the
NMC Upper-Air Dictionary
and NMC Office Note 29 were changed to
conform with the WMO BUFR
table of instrument types valid at that
time. The WMO BUFR
instrument types are listed in Table
R.2b.
2) A new
set of quality mark indicators was added as a
result of the implementation of the Complex
Quality Control of
rawinsonde heights and temperatures (CQCHHTMP)
which replaced
the hydrostatic check (HYDROCHK) program
on 1200 UTC 10 June
1992.
Changes specified by Revision 1 (October
10, 1969), Revision 2
(September 14, 1973), Revision 3 (April
30, 1987) as well as
those in Revision 4, have been incorporated
in this final
revision. All previous editions
will be obsolete.
Prior to
March 1997, information contained in NMC
observational data found in NMC production
files ADPUPA, AIRCFT,
SATWND, AIRCAR and UPABOG consists of
combinations of characters
from the FORTRAN character set given in
APPENDIX
A.
A report
is composed of two main parts: (1) the report
identification of fixed length (50 characters),
and (2) the
observational data of variable length.
Each report is
considered to be a logical record and
contains 70 or more
characters. The total number of
characters in a report is
evenly divisible by 10. Certain
portions of the report are also
evenly divisible by 10, and the character
"X" is used to fill in
these instances.
The information
contained in the report identification is
given in APPENDIX B.
The last parameter in this group contains
the total number of ten-character words
in the report providing
linkage from one report to the next when
a roup of reports is
blocked into a physical record.
The report identification is
followed by the observational data which
is formatted according
to the categories described in APPENDIX
C. Each category of
available data is preceded by a ten-character
category/counter
group which is described in APPENDIX
B. Where no data of a
given category exist, the category/counter
group also will be
absent from the report. The final category/counter
group in a
report contains the ten characters "END
REPORT". The total
number of characters found in the category/counter
group and the
formatted data for that category is evenly
divisible by 10, the
character "X" being used for fill if necessary.
A sample
RAWINSONDE report, in the prescribed format, is
given in APPENDIX D.
A negative
value of a parameter is indicated by a minus
(-) sign located in the leftmost position.
A positive value is
unsigned. All numbers are right-justified
with zero (0) fill.
In order
to attain flexibility for adding new report types
and/or new categories of data, programs
should be written so
that these additions will not necessitate
reprogramming. Of
course, to utilize the additional data,
programming would be
needed. This can be simply done
by providing a check to
ascertain if the report type and/or category
can be handled. If
not, the report or category should be
bypassed, pending a change
to utilize the additional data.
This Office
Note no longer describes the NMC format for
surface reports. See NMC
Office Note Number 124 for such
information.

APPENDIX C
Whenever values are "missing", all
characters allowed
for that parameter will contain
"9", except for quality
marks which will always be as stated.
Category 01 -- Mandatory constant-pressure data
(22 characters each entry) (see Note 1)
The assumed order of constant-pressure
data is as follows:
(1)
1000 mb (8) 200 mb
(15) 10 mb
(2)
850 mb (9) 150 mb
(16) 7 mb
(3)
700 mb (10) 100 mb
(17) 5 mb
(4)
500 mb (11) 70 mb
(18) 3 mb
(5)
400 mb (12) 50 mb
(19) 2 mb
(6)
300 mb (13) 30 mb
(20) 1 mb
(7)
250 mb (14) 20 mb
Assuming
this order, the entry in the category/counter
group which gives the number of
times a format is repeated
will be the number corresponding
to the highest level (lowest
pressure) for which there is data.

does write to temporary data sets which are input to the NMC
regional analysis. The quality mark characters assigned by
PREPACFT are found in Table Q.6d.

Note 1 - For AIREP, PIREP, and ASDAR aircraft data

August 1992: The character "P" in the first quality indicator
position followed by a blank in the second quality indicator
position indicates the entire report has been manually

Note 1 - AIREP and PIREP aircraft data are quality
controlled and
SUPEROBed by a program called "PREPACFT" prior to input into
some NMC analyses.
Note 2 - Prior to 12/4/91 ASDAR aircraft wind reports
could be SUPEROBed;
after this date, they are always treated as isolated reports
that cannot be SUPEROBed. They receive a wind quality mark of
"N" unless the quality mark is originally "H" or "P".
Note 3 - Only wind data are SUPEROBed. However,
the quality mark for
all variables is assigned an "S" and the station
identification is "SUPROB".
