For all the messages: extract the first temperature value which is greater than 300 K and also extract the pressure on which it occurs

Code Block
extract_data: on parameter_1: airTemperature parameter_operator_1: > parameter_value_1: 300 coordinate_condition_count: 1 coordinate_1: pressure

Here we explicitly say the that we only want the matching temperature values which appear inside a pressure block (in for these messages this is always the case). By using the coordinate condition pressure will also be extracted as well because the EXTRACT_COORDINATE option is On by default.

For all the messages: extract the first temperature value which is greater than 300 K and the pressure is less than 950 hPa

Code Block
extract_data: on parameter_1: airTemperature parameter_operator_1: > parameter_value_1: 300 coordinate_condition_count: 1 coordinate_1: pressure coordinate_operator_1: > coordinate_value_1: 95000

Here we further refined the coordinate condition.

For all the messages: extract the temperature value on the 500 hPa pressure level

Code Block
extract_data: on parameter_1: airTemperature coordinate_condition_count: 1 coordinate_1: pressure coordinate_operator_1: = coordinate_value_1: 50000

For station 78016: extract the temperature on the second pressure level

Code Block
identifier_value: 78016 extract_data: on parameter_1: airTemperature coordinate_condition_count: 1 coordinate_1: pressure coordinate_rank_1: 2

Here we restricted the filter for one station (message) only and used a rank condition for the coordinate.

For station 78016: extract the temperature on the first 6 pressure levels

Code Block
identifier_value: 78016 extract_data: on parameter_1: airTemperature coordinate_condition_count: 1 coordinate_1: pressure coordinate_rank_1: 1/2/3/4/5/6 extract_mode: all

For coordinate rank a list of values can be specified.

For station 78016: extract the temperature on the 925, 850 and 700 hPa pressure levels

Code Block

identifier_value: 78016
extract_data: on
parameter_1: airTemperature
coordinate_condition_count: 1
coordinate_1: pressure
coordinate_operator_1: =
coordinate_value_1: 92500/85000/70000
extract_mode: all
