How to do weighted average in a point location from gridded data

Dear NCL users,

    I have a 25 km resolution of global gridded data and I want to get the
data in a single station location with a weighted average from the nearby
grids.
Does there exists any NCL function which takes care of this issue.

Thanking you in advance
