CLASS 01-02 WMO CODE/FLAG TABLES ASSOCIATED WITH BUFR TABLE B

(Version 16.0.0 – 05/04/2011)

 

Changes awaiting validation by the WMO are in red (last updated by the WMO 05/04/2011)


Notes:   In developing code tables associated with BUFR/CREX Table B to specify units of elements, the following principles should be applied:

 

(a)   Code tables specifying the units for an element which is defined, in the Manual on Codes, by a single symbolic letter shall be compatible with the relevant existing WMO code tables;

 

(b)   Code tables combining two or more existing WMO code tables to specify the units for an element which is defined, in the Manual on Codes, by a group of symbolic letters shall be compatible with the combined code figures of the relevant group of symbolic letters;

 

(c)   Code tables combining two or more existing WMO code tables to specify the units for an element which is defined, in the Manual on Codes, by different symbolic letters shall be compatible with the code figures of the relevant symbolic letters, with successive tens or hundreds values added, as different symbolic letters appropropriate;

 

(d)   Code tables and flag tables should only be used for reporting qualitative information. Quantitative information should be reported as observed using entries in Table B.  "Data description operators" from Table C should be applied when a "scale change" or "data width change" is required;

 

(e)  Reference to existing specification(s) and code table(s) in the Manual on Codes, with explanation of possible deviations, shall be given in an additional table annexed to the annexed  to the code tables associated with BUFR/CREX Table B.

(2)  Partly cloudy path means the sounding has been generated from clear radiances which have been calculated from partly cloudy spots. Tropospheric and stratospheric HIRS data, as well as MSU and SSU data, have been used.

 

(3)  Cloudy path means the sounding has been generated only from stratospheric HIRS data, MSU data and SSU data. Tropospheric HIRS data have not been used because of cloudy conditions.

Notes:

 

1.   Clear sounding indicates the sounding has been generated from a set of clear radiances using all available sounder radiances.

 

2.   Cloudy sounding indicates that sufficient clear radiances could not be identified in the sounding area. The sounding is calculated from the cloud top (cloud pressure greater than or equal to 70 hPa) upwards.
