Table D is a device to reduce these overheads; Each entry within Table D contains a list of descriptors. Each sequence descriptor that references to Table D may be expanded by replacing it with the list corresponding to that entry. The process of expansion is well defined, provided it results in a set of element descriptors and operator descriptors; Descriptors listed in entries to Table D may themselves refer to Table D, provided no circularity results on repeated expansion; The initial Table D has been limited to lists of descriptors likely to be used frequently. Every attempt has been made not to produce initial tables that are too comprehensive. Minor differences of reporting practice can be accommodated by not endeavouring to reduce each observation type to a single descriptor. Indeed, much more flexibility is retained if the Data description section is envisaged as containing three or four descriptors. (2) It should be noted that, initially, effort has been concentrated on the requirements for observational data. Extensions forecast data, time series data, products, etc., follow logically and can be added at an appropriate future date. (4) Underwater soundings are included, with some minor omissions, to illustrate the facility to describe data of slightly different contents. (7) Categories 48 to 63 are reserved for local use; all other categories are reserved for future development. (8) Entries 192 to 255 within all categories are reserved for local use. Editorial note: Notes are numbered so as to be consistent with the BUFR Table D for convenience. I.2 CREX Table D 1

3 Category 00 CREX table entries sequences D D F, X, of descriptor to be added or defined B Descriptor defining sequence (Code table definition) D B Descriptor defining sequence R Delayed replication of 2 descriptors Up to 9999 entries B Code figure B Code figure meaning (Flag table definition) D B Descriptor defining sequence R Delayed replication of 2 descriptors B Bit number B Bit number meaning Notes: (1) These entries include the facility to update the Table A code figure and data description. (2) It is better to use different Class 00 descriptors for the defining and defined elements, in the same way as different descriptors correspond to pressure considered as a coordinate and pressure measured at a given point; otherwise special rules would be needed to interpret such message. Entries B to B define F, X and for Tables B and D; entry B is a descriptor used as data and provides the F, X and values defining a sequence for Table D entries. (3) It could be argued that, as only additions are possible, only complete lines should be allowed; but it is conceivable that local areas will require changes as well as additions, so it is better and in any case clearer to provide descriptions for all the fields.

5 Category 01 Location and identification sequences (Description of a feature in 3-D or 2-D) D B Dimensional significance = 0 Point, = 1 Line, = 2 Area, = 3 Volume (see Note 5) D Horizontal section of a feature described as a polygon, circle, line or point B Dimensional significance Set to missing (cancel) Note: (5) This replication factor shall have a value of 1 when a 2-D feature is being described, whereas 3-D features may be described via any one of the following methods: (a) Via two or more horizontal sections in successive ascending flight levels. In this case, each section shall be described by an identical number of latitude/longitude points listed in identical order (i.e. where each point x of section n is to be joined via a straight line to point x of section n+1), in order to ensure that the overall shape of the 3-D feature is unambiguously described. In this case, all values reported for B shall be missing. (b) Via a single horizontal section with an appropriate value reported for B , as follows. In all such cases, the corresponding horizontal section description applies throughout the entire region. (c) (i) (ii) (iii) (iv) A value of 0 to indicate a region above (but not including) the reported flight level and with unspecified upper bound. A value of 1 to indicate a region above (and including) the reported flight level and with unspecified upper bound. A value of 2 to indicate a region below (but not including) the reported flight level and extending to the surface. A value of 3 to indicate a region below (and including) the reported flight level and extending to the surface. Via two replications of the same horizontal section at the same reported flight level, in order to indicate a region extending both below and above (and including!) the reported flight level. In this case, the values reported for the two replications of B shall be as follows: (i) (ii) Values of 3 and 1, respectively, to indicate a region beginning from below a reported flight level, but continuing through that level upward to some unspecified point above (e.g. TOP ABV FL100). Values of 1 and 3, respectively, to indicate a region beginning from above a reported flight level, but continuing through that level downward to some unspecified point below (e.g. CIGS BLW FL010).
