Interpolation on onto rcm grid

Description

Hi,
I'm attempting to create ancil files for the vn4.5 LAM. I wish to interpolate fields onto the rotated higher resolution grid. Is this done just using bilinear interpolation for all fields? Since it would appear that for say sea ice fraction: the average fraction of all of the interpolated grid boxes contained in a given original grid box should have the same average fraction as the larger box etc. Do features like this get taken into account by using area weighting etc?

Thanks
Jonny

Can you say what software you are trying to use to do this. Thanks.

Hi Jeff,
I'm using IDL for this procedure but am not adverse to other suggestions.

Cheers
