Hi,
all
I have a skin temperature data set in
ASCII format, which includes data on the continent and sea. The data set is located on Gauss grid, that's
grid in the meridional direction is irregular. Like the following
grid:
I/97.5e:121.875e :1.875
J/4.6s:23.5n: about 1.875(irregular
spaced)
I used the follow *.jnl for drawing a
plot, and I found the map I draw is
in the shape of ladder(like the background), but not continuous and smoothing?
Is that relative to the resolution of the above data? If yes, How should I
settle it?
Thanks a lot.
