[gradsusr] problems opening netcdf variable

[Andrew Friedman]

Hi everyone,

I found one way to solve the problem using NCO: I extracted the relevant 
variable, and then removed the depth dimension as follows:

ncks -O -v lat,lon,time,h18_hc NODC_heat_content_anomaly_0-700_yearly.nc 
NODC_yearly_h18_hc.nc
ncwa -a depth NODC_yearly_h18_hc.nc NODC_yearly_h18_hc.nc

Best,
Andrew
