Dear All,
I have a NetCDF file and the description is in accessary, I use " ncdump
-v layer_absorber profile.nc > out.txt" to extract the data, but there are
so many data extracted.
For instance, The description of "layer_absorber" as following:
#
double layer_absorber(n_profiles, n_absorbers, n_layers) ;
layer_absorber:long_name = "Layer absorber" ;
layer_absorber:units = "Variable (see Absorber_Units_ID)" ;
layer_absorber:_FillValue = -999. ;
#
Could you tell me how to extract the data of " layer_absorber(1,1,1:100) "
?
Thank you.
Sincerely.
