REASON CODES ASSOCIATED WITH STEP VIRTMP, PROGRAM CODE 008

Table 14. Reason codes associated with step "VIRTMP", program code 008 (last revised 1/4/2008).

NOTE:
See the document "Summary of Virtual Temperature Processing in PREPBUFR" for more information.

KEY:
IN "R.CODE" COLUMN:
B - OCCURS IN ALL OPERATIONAL VERSIONS OF VIRTMP EXCEPT RUC (THE VIRTMP STEP DOES NOT RUN IN THE RUC NETWORK).

IN "MNEMONIC" COLUMN:
# - NEW VALUE CALCULATED.

R.CODE MEANING MNEMONICS AFFECTED AND NEW VALUE FOR OBS, Q.M.

00 B SPECIFIC HUMIDITY OBSERVATION IS REGENERATED FROM REPORTED DEWPOINT TEMPERATURE AND PRESSURE. (DEWPOINT TEMPERATURE HAS UNDERGONE POSSIBLE CQC AND RADIATION CORRECTIONS). THIS IS PERFORMED IN THE W3LIB ROUTINE GBLEVENTS. QRC-> QOB=#

00 B TEMPERATURE OBSERVATION IS CONVERTED TO VIRTUAL TEMPERATURE, CALCULATED FROM THE REGENERATED SPECIFIC HUMIDITY (SEE R. CODE 00 ABOVE OR 01 BELOW) AND FROM A SENSIBLE TEMPERATURE OBSERVATION THAT HAS UNDERGONE POSSIBLE COMPLEX QUALITY CONTROL AND RADIATION CORRECTIONS. THIS IS PERFORMED IN THE W3LIB ROUTINE GBLEVENTS. TRC-> TOB=#

01 B SPECIFIC HUMIDITY OBSERVATION IS REGENERATED FROM REPORTED DEWPOINT TEMPERATURE AND PRESSURE. (DEWPOINT TEMPERATURE HAS UNDERGONE POSSIBLE CQC AND RADIATION CORRECTIONS). THIS IS PERFORMED IN THE PROGRAM PREPOBS_CQCBUFR. QRC-> QOB=#

01 B TEMPERATURE OBSERVATION IS CONVERTED TO VIRTUAL TEMPERATURE, CALCULATED FROM THE REGENERATED SPECIFIC HUMIDITY (SEE R. CODE 00 OR 01 ABOVE) AND FROM A SENSIBLE TEMPERATURE OBSERVATION THAT HAS UNDERGONE POSSIBLE COMPLEX QUALITY CONTROL AND RADIATION CORRECTIONS. THIS IS PERFORMED IN THE PROGRAM PREPOBS_CQCBUFR. TRC-> TOB=#

02 B TEMPERATURE OBSERVATION IS CONVERTED TO VIRTUAL TEMPERATURE, CALCULATED FROM THE REGENERATED SPECIFIC HUMIDITY (SEE R. CODE 00 OR 01 ABOVE) AND FROM A SENSIBLE TEMPERATURE OBSERVATION THAT HAS UNDERGONE POSSIBLE COMPLEX QUALITY CONTROL AND RADIATION CORRECTIONS. EITHER THE SPECIFIC HUMIDITY HAS A REJECTED QUALITY MARKER OTHER THAN 9 OR 15 - OR - THE SPECIFIC HUMIDITY HAS A REJECTED QUALITY MARKER OF 9 OR 15 AND THE SENSIBLE TEMPERATURE QUALITY MARKER IS REJECTED BUT WITH A VALUE OTHER THAN 9 OR 15. VIRTUAL TEMPERATURE IS CONSIDERED REJECTED. THIS IS VALID ONLY FOR SURFACE LAND OR MARINE DATA TYPES. THIS IS PERFORMED IN THE W3LIB ROUTINE GBLEVENTS. TRC-> TOB=#, TQM=8

03 B REPORTED TEMPERATURE OBSERVATION IS ALREADY VIRTUAL. NO CONVERSION IS NECESSARY. THIS IS PERFORMED IN THE W3LIB ROUTINE GBLEVENTS. TRC-> no values changed

04 B TEMPERATURE OBSERVATION IS CONVERTED TO VIRTUAL TEMPERATURE, CALCULATED FROM THE REGENERATED SPECIFIC HUMIDITY (SEE R. CODE 00 OR 01 ABOVE) AND FROM A SENSIBLE TEMPERATURE OBSERVATION THAT HAS UNDERGONE POSSIBLE COMPLEX QUALITY CONTROL AND RADIATION CORRECTIONS. THE SPECIFIC HUMIDITY HAS A REJECTED QUALITY MARKER OF 9 OR 15 AND THE SENSIBLE TEMPERATURE QUALITY MARKER IS EITHER NOT REJECTED OR IS REJECTED BUT WITH A VALUE OF 9 OR 15. VIRTUAL TEMPERATURE IS CONSIDERED REJECTED. THIS IS VALID ONLY FOR SURFACE LAND OR MARINE DATA TYPES. THIS IS PERFORMED IN THE W3LIB ROUTINE GBLEVENTS. TRC-> TOB=#, TQM=9 (see % below)

06 B TEMPERATURE OBSERVATION IS CONVERTED TO VIRTUAL TEMPERATURE, CALCULATED FROM THE REGENERATED SPECIFIC HUMIDITY (SEE R. CODE 00 OR 01 ABOVE) AND FROM A SENSIBLE TEMPERATURE OBSERVATION THAT HAS UNDERGONE POSSIBLE COMPLEX QUALITY CONTROL AND RADIATION CORRECTIONS. THE SPECIFIC HUMIDITY HAS A REJECTED QUALITY MARKER OTHER THAN 9 OR 15, THE PRESSURE LEVEL IS BELOW 700 MB, AND THE SENSIBLE TEMPERATURE QUALITY MARKER IS EITHER 1, 2 OR 3. VIRTUAL TEMPERATURE IS CONSIDERED SUSPECT. THIS IS VALID ONLY FOR RADIOSONDE, DROPWINSONDE, AND MULTI-LEVEL RECONNAISSANCE DATA TYPES. THIS IS PERFORMED IN THE W3LIB ROUTINE GBLEVENTS. TRC-> TOB=#, TQM=3

07 B TEMPERATURE OBSERVATION IS CONVERTED TO VIRTUAL TEMPERATURE, CALCULATED FROM THE REGENERATED SPECIFIC HUMIDITY (SEE R. CODE 00 OR 01 ABOVE) AND FROM A SENSIBLE TEMPERATURE OBSERVATION THAT HAS UNDERGONE POSSIBLE COMPLEX QUALITY CONTROL AND RADIATION CORRECTIONS. THE SPECIFIC HUMIDITY HAS A REJECTED QUALITY MARKER OTHER THAN 9 OR 15, THE PRESSURE LEVEL IS BELOW 700 MB, AND THE SENSIBLE TEMPERATURE QUALITY MARKER IS EITHER 1, 2 OR 3. VIRTUAL TEMPERATURE IS CONSIDERED SUSPECT. THIS IS VALID ONLY FOR RADIOSONDE, DROPWINSONDE, AND MULTI-LEVEL RECONNAISSANCE DATA TYPES. THIS IS PERFORMED IN THE PROGRAM PREPOBS_CQCBUFR. TRC-> TOB=#, TQM=3

% - PRIOR TO 12/04/2007 THE QUALITY MARKER WAS SET TO 8 IN THIS CASE.
