conditions for multivariate EOF

[jiwon-j]

hello,
i'm trying to do multivariate EOF with precipitation and sea surface temperature data.
but their resolutions are different.
do they need to have same resolution?
also, do they need to have same number of grid?
i want to set the domain for each variable to be different (ex, SST for Asia and Precipitation for Pacific)

I think the two datas just need have the same time series, that is ok for EOF, just have a try !
