Change Daily Data to "Monthly Data" Without Averaging

Added by Justin Hicks almost 6 years ago

Hello,

I'm looking to change daily data into "monthly data"; however, I do not want to average the daily steps into a single monthly step (i.e. "cdo monthmean" would not work). Instead, I am looking to have the first daily time step (00z01jan2000) be the first time step in the monthly file, and I want 00z01feb2000 to be the second time step in the monthly file...and so on. Is there any way to do this in CDO? I tried making a control file to do this in GrADS, but it is not working correctly.

Thanks,

-Justin
