[PYTHON MATRIX-SIG] handling missing data values in NumPy

I often deal with time sequences of 2D arrays that have
some values missing at random times. I want to obtain
an average of these sequences along the time axis
taking into account the missing values.
I may just be dense but I do not see any slick way to
accomplish this task without writing an extension 
like the add.reduce but checking each element for
a missing value.

Does anyone have any insight to this problem or is an
extension the solution?

Thanks for any information.
