20-90 days Bandpass Filter

Added by johnug N about 8 years ago

Hi,
I am trying to use 20-90 days bandpass filter and getting the following error. Has anyone met this before? Any suggestion?

cdo bandpass,365/90,365/20 daily.1972.nl.nc highpass.latent.nc

cdo bandpass (Abort): Float parameter >365/90< contains invalid character at position 4!

I have removed the 29Feb from original surface latent heat data.
Then I failed to filter the data.

Thanks.
Regards
Johnug

365/90 is an invalid parameter for this operator. The operator bandpass expects 2 float parameter. You have to divide 365/90 and pass the result to bandpass:

cdo bandpass,4.055555,18.25 daily.1972.nl.nc highpass.latent.nc
