I have regular arrayed data (1440*720). I'd like to change this data
to 360*180 array.
So I use 'Rebin' function.
But these data have NaN value.
If I use Rebin and there is a NaN value, new array becomes also NaN.

For example, if there is only one NaN in the old array, the new-array
becomes NaN. But I want to make a new array except NaN data. This
situation makes residual data wasteful.

A = [1.5,2.5,3.6,4,7,8.8,9.0,!values.f_nan]
print, rebin(A, 1)
;result is 'NAN'
;That I expected value is mean(A, /nan)

Is there any know-how to change array except NaN?
