1 Description
The generating process dictionary "process.grib2" is used by grib2_encode and grib2_decode
to do the translation between the RPN standard file label and the GRIB2 process parameters.
2 Entry format
Lines with a '#' in the first column (comment lines) and empty
lines are not treated. For a dictionary entry to be valid, all
elements must be present and on the same line. Anything
following on the line is considered as comments.
| Note: | "--" is used as a "Not considered" flag. The entries wich use the "Not considered" flag have a lower matching priority (see Selection of dictionary entries; ). |
An entry is composed of the following elements:
Grib section
|
||||||||||||||||||||||||
RPN Standard file section
|
<a name="selection">
3 Selection of dictionary entries
The dictionary entry is selected following these rules:
- A weight is given to each entry
- The entry with the largest weight is selected
- The dictionary is scanned from top to bottom, so if entries have the same weigth, the one encountered first is selected
- The total weight of an entry is obtain by adding the weight to each of its elements
- Entry elements with a value of "--" are ignored
- If an element's value does not match the record's corresponding value, the entry is rejected
Weight of each element:

4 Example
Here are a few example entries. Lines beginning with # are comment. they help keeping track of entry elements.
