[gradsusr] Fwd: gr2stn: Dealing with missing values

[Jonas Kaufmann]

Hello,

I am extracting station data using the gr2stn function. The documentation
for this function reads:

"If any of the four grid points around the station location are missing,
the result will also be missing."
...and...
"the -n option may be used to return the nearest grid point value"

Is it possible to combine those two approaches? If any of the four grid
points around my station location are missing, then automatically return
the nearest grid point value?


Thank you for your help!

Jonas
