For all the messages: extract the first wind speed and wind direction values


Code Block
extract_data: on
parameter_count: 2 parameter_1: windDirection
parameter_2: windSpeed



Note

The order of the parameters in extraction must match their order of appearance in the message. Otherwise the data alignment does not work properly. In our BUFR messages windDirection precedes windSpeed, so we have to use the same ordering in the filter definition.


For all the messages: extract the first wind speed and wind direction values and also extract their pressure


Code Block
extract_data: on
parameter_count: 2 parameter_1: windDirection
parameter_2: windSpeed
coordinate_condition_count: 1
coordinate_1: pressure



For all the messages: extract wind speed and wind direction values on the 500 hPa pressure level


Code Block
extract_data: on
parameter_1: windDirection
parameter_2: windSpeed
coordinate_condition_count: 1
coordinate_1: pressure
coordinate_operator_1: =
coordinate_value_1: 50000
