Dear List, I am not sure if I interprete the word "parametric" correctly.
Does "Parametric Vertical Coordinates" mean that there is a mathematical function, which describes the relation between the relevant (auxiliary) coordinate variables and the parametric vertical coordinate?
Speaking in terms of the example provided further below: Value of `depth` is a `f(time, lev, lat, lon)`, whereas `f` is a mathematical function with considerably less parameters than `depth` has values. Then `depth` is a parametric vertical coordinate.
Formulated the other way arond: Is `depth` NOT a parametric vertical coordinate if its values are somehow set by hand (by a human), calculated by some nested if-clause, or by some iterative procedure?
If `depth` is not a parametric vertical coordinate in this sense, am I allowed to use it in a CF-compliant file?
Example:
...
int lev(lev):
lev:standard_name = "model_level_number" ;
lev:long_name = "model_level_number" ;
lev:positive = "down" ;
lev:units = "1" ;
double depth(time, lev, lat, lon);
depth:long_name = "depth" ;
depth:positive = "down" ;
depth:standard_name = "depth" ;
depth:units = "m" ;
depth:axis = "Z" ;
float some_data_variable(time, lev, lat, lon);
some_data_variable:standard_name = "some_standard_name" ;
some_data_variable:units = "some_unit" ;
some_data_variable:coordinates = "depth"
...
Cheers,
Daniel
