Appendix 5. Additional Quality Codes

PROC1, PROC2, PROC3 and INSTRUMENT. Taken from pages 6, 7 and 9 of Mulder (1977).

Table A 5.1
PROC1

Assigned to indicate special processing procedures.

	PROC1

Value                  Meaning

   0		Report has been adjusted to map time by an NMC updating
		procedure.  Heights are referenced to some forecast level

   1		Report has been adjusted to map time by an NMC updating
		procedure.  Heights are referenced to 1000 mb level at sea level.

   8		Reported heights are referenced to 1000 mb level at sea level.

   9*		Reported heights are referenced to some forecast level.

		*Except for report type 061 (SIRS), this value means "missing" or not applicable

Table A 5.2
PROC2

Assigned to indicate the information specifying that the standard isobaric surfaces were located by use of pressure equipment, or that pressure equipment was not available and the wind data were reported at altitudes approximating the standard isobaric surfaces.

	PROC2
Value		Equipment

   0		Pressure instrument associated with wind-measuring equipment.
   1 or 5	Optical theodolite.
   0 or 2	Radio theodolite.
   3 or 7	Radar.
   4		Pressure instrument associated with wind-measuring equipment but
   		pressure element failed during ascent.
   6		Not assigned.
   8		Not assigned.
   9		Not specified.

Table A 5.3
PROC 3

Assigned to indicate results of processing.

	

Value		Meaning

   0		All parameters in the report have been processed automatically
		(no manual intervention).

   1		All parameters in the report have been obtained by manual
		intervention (no automatic processing).

   2		All parameters in the report have been obtained by manual
		intervention and all parameters agree with automatically
		processed values.

   3		All parameters in the report have been obtained by manual
		intervention and all parameters disagree with automatically
		processed values.

   4		All parameters in the report have been obtained by manual
		intervention and one or more parameters disagree with
		automatically processed values.

   5		One or more, but not all, parameters in the report have been
		obtained by manual intervention and all of these parameters
		agree with automatically processed values.

   6		One or more, but not all, parameters in the report have been
		obtained by manual intervention and all of these parameters
		disagree with the automatically processed values.

   7		Two or more, but not all, parameters in the report have been
		obtained by manual intervention and one or more parameters
		agree and one or more parameters disagree with the
		automatically processed values.

   8		Not assigned.

   9		Not specified.
