get_true_latitude_variables

compliance_checker.cfutil.get_true_latitude_variables(nc)

Returns a list of variables defining true latitude.

CF Chapter 4 refers to latitude as a coordinate variable that can also be used in non-standard coordinate systems like rotated pole and other projections. Chapter 5 refers to a concept of true latitude where the variable defines latitude in a standard projection.

True latitude, for lack of a better definition, is simply latitude where the standard_name is latitude or the units are degrees_north.

Parameters:

nc (netCDF4.Dataset) – An open netCDF dataset
