[ncl-talk] linint2_point

[Ian Harris (ENV - Staff)]

Hi,

I'd say they want you to examine the resolution of your input and output data, in case the interpolation could be judged, er, 'optimistic'. For instance, if I had data on a 5° grid, I could easily interpolate it onto a 0.5° grid, but there are implications because you're not inventing new data, you're still stuck with the 5° data but on a finer grid.

Cheers

Harry

Dear NCL group,
I hope you're doing great.
I have a general question and I hope I could have your help, as usual.
In one paper I wrote "The interpolation was done using the bilinear method in NCL (NCAR Command Language)". Actually, I interpolated some grid precipitation products on gauged stations using "linint2_points" from NCL.
The referee commented "With how many points? Please discuss also the spatial scale resolution differences in products and interpolation implications."
I wanna reply "As mentioned in the paper, we used NCL in the most programming. NCL has a function named linint2_points which interpolates from a rectilinear grid to an unstructured grid using bilinear interpolation based on the four closest grid points to a particular (x, y) coordinate pair." However, I don't know how reply to the part of discussing about different spatial resolution. May I ask some help about that, please?
