My original proposal was Add a standard_name complex_parts to "tag" the dimension that corresponds to complex parts. so that we could tag a coordinate variable of a real-valued netcdf variable as corresponding to the real/imaginary direction, e.g. complex sst(C,X,Y,F) would have dimensions: C = 2; Y = 30 ; X = 84 ; F = 399 ; variables: integer C(C) ; C:standard_name = "complex_parts" ; float Y(Y) ; Y:standard_name = "latitude" ; Y:units = "degree_north" ; float X(X) ; X:standard_name = "longitude" ; X:units = "degree_east" ; float F(F) ; F:standard_name = "frequency" ; TFunits = "1/sec" ; float ssta(Y, X, F, C) ; ssta:long_name = "Sea Surface Temperature Anomaly" ; The conversation then got rapidly more complicated. -- Dr. M.
