Description
grouptogrid groups data from a
set of n dependent variables (name1, name2,
..., namen) from a data set in the Data Library as if
they were all from one variable dependent upon a newly-created grid (M)
with grid points named after the original dependent variables.
Example
In
the following example, grouptogrid is applied to the monthly mean
zonal (u) and meridional (v) wind variables (which originally depend
upon pressure level (P), time (T), longitude (X), and latitude (Y)
grids) from the NCEP-NCAR Reanalysis data set. The result is a single
variable containing both the zonal and meridional wind data, but which
is now indexed by the original P, T, X, and Y grids and, additionally, a
new 2-point grid named "M" whose grid values are named "u" (to which the
zonal wind values are assigned) and "v" (to which the meridional wind
values are assigned).
