Documentation of Filters (i.e bandpass) in CDO
Added by Lyndon Mark Olaguera over 7 years ago
Hi all,
I am using the bandpass command in CDO. I would like to properly document this method. Where can I find the reference of the equations in these functions especially the bandpass and higpass filters?
Many Thanks

Hi everyone,
I am also using the bandpass command in CDO and I am very much interested in where I can find a documentation or reference of the equations that are used. I am especially interested in what happens in the beginning and the end of the used timeseries, since I am only filtering a one year dataset. I tested it and if I start with June as first month I get a different result for June than when I start my timeseries in January and then look at the result for June. Now I am wondering how much of the result is "problematic", i.e. days, weeks or the whole first and last month, and how I could properly find out. I tried checking out the source code but I was not able to figure it out on my own.
I would be super happy, if you could help me!
Thank you!
Cheers,
Thea
