Interpolation Library 2

The NCEPLIBS-ip2 library has been deprecated. Please do not use it in new work. All functionality from the NCEPLIBS-ip2 library has been merged into the NCEPLIBS-ip library. Please use the NCEPLIBS-ip library for all future development. No further release of NCEPLIBS-ip2 will be made.

The NCEP general interpolation library 2 contains Fortran 90 subprograms to be used for interpolating between nearly all grids used at NCEP. The library is particularly efficient when interpolating many fields at one time.

This is part of the NCEPLIBS project.

There are currently six interpolation methods available in the library:

• bilinear
• bicubic
• neighbor
• budget
• spectral
• neighbor-budget

To submit bug reports, feature requests, or other code-related issues including installation and usage questions, please create a GitHub issue. For general NCEPLIBS inquiries, contact Edward Hartnett (secondary point of contact Alex Richert).
