Regridding
There are numerous
regridding functions available in NCL. Try following our new
regridding decision tree to
help you choose.
regrid_1.ncl: An example of using
linint2, which interpolates from one grid to another using bilinear
interpolation.
regrid_2.ncl: An example of using
g2gsh, which interpolates from one gaussian grid to another using
spherical harmonics.
example, the actual interpolation is conducted using g2gsh_Wrap, a wrapper function that will assign all the appropriate meta data, including the gaussian latitudes, to resulting output.
regrid_3.ncl: An example of using
g2fsh, which interpolates from one gaussian grid to a fixed grid
using spherical harmonics.
regrid_4.ncl: An example of using
f2fsh, which interpolates from one fixed grid to another
using spherical harmonics.
regrid_5.ncl: An example of using
f2gsh, which interpolates from a fixed grid to a gaussian grid
using spherical harmonics.
Even though this example uses f2gsh_Wrap the coordinate variables could be created manually. See example one for the creation of the longitude array. The resulting gaussian latitude array can be created using latGau.
