Hi ferreters,

          I want to compare daily climatologies for two 10 years datasets with different time axes. There is 6 hours shift in DATA2 as compared to DATA1 (see below).
Can anybody help me how to calculate daily climatologies considering the different time axes of datasets.

Thanks in advance
Ashley
