For all the messages: extract the first non missing temperature value


Code Block
extract_data: on
parameter_1: airTemperature


By default missing values are ignored in data extraction (see option MISSING DATA)
For all the messages: extract the first (rank=1) temperature value (if missing it is ignored)


Code Block
extract_data: on
parameter_1: airTemperature
parameter_rank_1: 1


Here we explicitly asked for the first temperature value. It has a missing value in many of the messages so we have less resulting rows that in the previous example.
For all the messages: extract the first (rank=1) temperature value if it is greater than 300 K


Code Block
extract_data: on
parameter_1: airTemperature
parameter_rank_1: 1
parameter_operator_1: >
parameter_value_1: 300



For all the messages: extract the first temperature value which is greater than 300 K


Code Block
extract_data: on
parameter_1: airTemperature
parameter_operator_1: >
parameter_value_1: 300



For station 78016: extract all the temperature values



Code Block
identifier_value: 78016
extract_data: on
parameter_1: airTemperature
extract_mode: all
