Access keys by rank:
Step-by-step guide
- Each key can appear several times in a BUFR message.
Examples are:
- airTemperature in an upper air report
- backscatter in a scatterometer observation
ecCodes provides access by rank of all the keys in the data section of a BUFR message with the following syntax:
#to get the third airTemperature in the messaget=codes_get(bufr,'#3#airTemperature')#to get the second backscatter in the messageb=codes_get_array(bufr,'#2#backscatter')- This is a change compared with the key syntax provided before version 0.12.0 where the access by rank was expressed as
'airTemperature#3'
