Regridding 3 dimensional data

[Lee Byerle]

John,
One way for you to retain your 3-dimensional dataset is to regrid each
2-dimensional array (use regrid), then use fwrite to create a new binary
with all 20 (re-gridded) levels.

Lee.

Here is an example:

set z 1

define newu1=regrid2(u,2.,2.,ba)

set z 2

define newu2=regrid2(u,2.,2.,ba)

set z 3

define newu3=regrid2(u,2.,2.,ba)

set lon 0 358
set lat -90 90
(assuming global dataset)

set gxout fwrite
set fwrite new.out
set z 1
d newu1
set z 2
d newu2
set z 3
d newu3
.
.etc.
disable fwrite.

good luck,
Lee
