The key “backscatter” will return an array with all the backscatter values in the BUFR tree, while will return the values of backscatter in the branch of the tree where the condition "beamIdentifier=3" is satisfied.

Access Keys by Condition:

Step-by-step guide

  1. The key “backscatter” will return an array with all the backscatter values in the BUFR tree, while:

    /beamIdentifier=3/backscatter

    will return the values of backscatter in the branch of the tree where the condition "beamIdentifier=3" is satisfied. 

  2. If the condition is satisfied by more than one branch, all the values for all the branches satisfying the condition are returned.

  3. As an example we can have in a TEMP message the need of getting the values of the temperature or humidity significant levels and this can be achieved by getting the values of the key:

    /verticalSoundingSignificance=4/dewpointTemperature


  4. This will return all the values of dewpointTemperature in the BUFR tree for which the verticalSoundingSignificance is 4.
