Hi Zibiao, This is "regridding". You will define the daily time axis that you want, and use a regridding operation to put the hourly data onto it. If you look in the Users Guide index under "average, @ave regridding" you will get the right information. A general suggestion as you learn to use Ferret is to read the first chapter of the Users Guide, and then scan chapters 2-4 and 6 to get an idea of the topics that are there. Happy Ferreting!

Hi, The topics to look up in the Users Guide are "hard copy" and "gif image". We will add some more index entries to make this information easier to find.
