What is ncregrid?
ncregrid is a tool (written in FORTRAN-90) for data transfer of gridded 2- and 3-dimensional (spatial) geophysical/geochemical scalar fields between grids of different resolutions. The algorithm handles data on rectangular latitude/longitude grids (not necessarily evenly spaced) and vertical pressure hybrid grids of arbitrary resolution. The input/output data format is netCDF.

ncregrid can be used as a "stand-alone"' program, and/or linked as an interface to a model, in order to re-grid automatically the input from an arbitrary grid space onto the required grid resolution.

ncregrid is freely available without any warranty under the GNU public license (GPL).

ncregrid is published; the following paper is freely accessible:

Please note also the electronic supplement of this paper!

The most recent version is: ncregrid 1.5b.

Since this software tool is still under development, any feedback is very much appreciated.
