Each key can appear several times in a BUFR message. Examples are:
- airTemperature in a upper air message
- backscatter in a scatteromenter observation
ecCodes provides access by rank of all the keys in the data section of a BUFR message with the following syntax:
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
#to get the third airTemperature in the message
t=codes_get(bufr,'#3#airTemperature')
#to get the second backscatter in the message
b=codes_get_array(bufr,'#2#backscatter') |
This is a change compared with the key syntax provided before version 0.12.0.
