[ncl-install] short2float problem

[Adam Phillips]

Hi Gwenaëlle,
First, please post general questions about NCL to the ncl-talk email list
and not to the ncl-install email list. You can subscribe here:
http://mailman.ucar.edu/mailman/listinfo/ncl-talk

Whenever you get a NclMalloc Failed error you are running out of system
memory. See: http://www.ncl.ucar.edu/FAQ/#err_msgs_001
for tips on how to proceed. In short, you likely need to read in fewer time
steps or reduce your spatial area.

Another method to try would be to use short2flt immediately upon read-in:
a = addfile("file.nc","r")
xF = short2flt(a->temperature_anomaly)

Finally, NCL v6.2.0 is 2 versions old; if you can it is recommended that
you install the newest version of NCL (v6.3.0) that was recently released.

Hope that helps. If not or if you have further questions, please respond to
the ncl-talk email list.
Adam
