When we use multiple coordinate conditions these are |
...
regarded as nested, i.e. |
...
the first coordinate specified is the outer coordinate, the next inner coordinate is nested in it and so on. This puts a |
...
constraint on the order the coordinate conditions |
...
: the outer coordinate has to be specified first then the other coordinates must follow in the nesting order. |
In the examples below we will work with two coordinates to extract radiosonde data on certain levels: pressure will be the outer coordinate and verticalSoundingSignificance, which defines the type of the pressure levels, the inner coordinate. It reflects how a pressure block is built up in our radiosonde BUFR file:
