Hi Ferreters,

I wonder if there is a simple way to return the values of the first (and last) non-missing data along a particular axis within a specified region. For example, let's say I'd like to return the temperature on the equator at the east coast of South America and west coast of Africa in Levitus.

see the @CIA and @CIB transforms (Closest [valid] Index Above/Below)

Thanks,
David
