Hi Dennis,
Thank you for your reply!
When I delete "(::5,::10)", the numbers of lat and lon are right but still have wrong names like this and cann't read by Panoply :
I never changed the names for lat and lon. I really don't know what had happened to this.
Thank you in advance for your time if you can take a look at this.

The data on the *file* may be 1676 x 4320
BUT you sub-sampled the data (decimated)
t = short2flt(in->med_c0(::5,::10))
decimates the lat dimension to 1/5 the original size (1676/5)
and
decimates the lon dimension to 1/10 the original size (4320/10)
-----
If you want to retain the original dimensions
t = short2flt(in->med_c0) ; read all the data
Good Luck
