Problem
You downloaded data from the ECMWF data server or another ECMWF repository in NetCDF format.
Then you are trying to read the data with the NCAR Command Language (NCL) but get an error message:
ncl 0> f = addfile("ECMWF-data.nc","r")(0) longitude (1) latitude (2) time (3) p83.162 (4) p86.162 q ncl 3> x = f->p83.162 fatal:syntax error: line 3 before or near .162 x = f->p83.162 -------------^ ncl 4> x = f->"p83.162" fatal:syntax error: line 4 before or near > x = f-> ------^ |
Please enclose the parameter name in Dollar signs and quotes:
ncl 0> f = addfile("ECMWF-data.nc","r")ncl 1> print (getfilevarnames (f)) ncl 2> x = f->$"p83.162"$ ncl 3> print (x) Variable: x Type: short Total Size: 7172160 bytes 3586080 values Number of Dimensions: 3 Dimensions and sizes: [time | 31] x [latitude | 241] x [longitude | 480] Coordinates: time: [1024872..1025592] latitude: [90..-90] longitude: [ 0..359.25] Number Of Attributes: 6 scale_factor : 0.6170104064936749 add_offset : -3072.290927078247 _FillValue : -32767 missing_value : -32767 units : W m**-2 long_name : Vertical integral of divergence of thermal energy flux |
