no, not if the field is not also a function of time... If you mean you want the correlation between a
1D field (function of time) and a
3D field (function of time, lon, lat) then
yes you can... you need to "project" the index onto the 3D grid first though using "enlarge"
cdo enlarge,my_3d_field.nc 1D_index.nc 3D_index.nc
then you can calculate the correlation
cdo fldcorr my_3d_field.nc 3D_index.nc corr.nc
