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 published; the following paper is freely accessible:

Note: Since Version 1.0b NCREGRID comprises a full interface to the Climate Model ECHAM-5 (see CHANGELOG_E5). A documentation of this specific interface (./ncregrid/examples/tools/messy_ncregrid_tools_e5.f90) is available as PDF: ncregrid_echam5_messy.pdf
