Re: Daily average

Hi Brandon,

Uou can use runave_Wrap:
http://www.ncl.ucar.edu/Document/Functions/Contributed/runave_Wrap.shtml

; arr is dimensioned time x lat x lon, data starts at 00Z Jan 1st

arr_ra = runave_Wrap(arr(lat|:,lon|:,time|:),2,0)
delete(arr)
;grab every other timestep and reorder
finarr = arr_ra(time|0::2,lat|:,lon|:)
delete(arr_ra)

As far as writing to a netCDF file, there are two methods that you can
use as is shown here:
http://www.ncl.ucar.edu/Applications/o-netcdf.shtml

Assuming you are not writing a complex (= writing a large number of
variables) or large (approaching 2GB in size), the simpler Method 1
should suffice.

Good luck,
Adam
