Hi,
I imagine that a better answer would be to find a dataset that has
wind values over land.
However you asked about the arguments to FILL_XY. Here is the
documentation for the function.
http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/appendix-a-external-functions/fill_xy
Often you can "ask Ferret" what it's doing - Make a set of plots to
show you the result of changing the argument.
yes? use coads_climatology
yes? let mask = 0*missing(uwnd,0)+1
! show the original data, then filled with different values of
N
yes? set view ul; shade/title="uwnd, no
filll"/x=60:170/y=-40:0/l=1 uwnd; go land
yes? let wx = fill_xy(uwnd,mask,1)
yes? set view ur; shade/title="fill,
cycle=1"/x=60:170/y=-40:0/l=1 wx; go land
yes? let wx = fill_xy(uwnd,mask,2)
yes? set view ll; shade/title="fill,
cycle=2"/x=60:170/y=-40:0/l=1 wx; go land
yes? let wx = fill_xy(uwnd,mask,4)
yes? set view lr; shade/title="fill,
cycle=4"/x=60:170/y=-40:0/l=1 wx; go land

Hi Martin,
Thanks for your detailed reply. I am trying to use the COADS
monthly climatology data for forcing my model and you are
absolutely right that model needs reasonable values over the
land preferably the values extrapolated from ocean. I will try
with your tips and inform you. I have one more doubt that, the
third argument of the fill_xy function, how can I decide the
proper value for it?
