Hi Paulo
there is a function "scat2grid" that grids scattered data. Check the
documentation for detailed explanations Ch3 Sec2.3:

Hi Ferreters,
I have some scattered precipitation data stored in a ASCII file
with
LON
in
first row, LAT in second row and with third to last rows being
daily
accumulated rainfall relative to that (lon,lat) beginning at
01-jan-2008
separated by semicolons, e.g.:
-39.05;-7.37;0;0;0;0;0;0;0;0;0;0;0;23;10;5;8 ;...
-40.12;-2.88;0;9.8;0;12.6;17.2;0;0;11;0;0;0;0;0;4.2;0 ;...
-39.58;-6.08;0;0;0;0;0;0;0;0;0;0;0;0;5;20;0 ;...
-40.12;-6.57;0;0;0;3;0;0;0;0;0;0;0;0;0;0;13 ;...
-40.55;-3.58;0;0;0;0;0;0;0;6;0;0;0;0;0;0;4 ;...
-39.73;-7;0;0;0;25.9;0;0;0;0.8;0;0;0;0;2.8;9.4;9.6;0 ;...
-38.25;-5.52;0;0;0;0;0;0;0;0;0;0;0;0;2;0;2.2;...
.

.
The full dataset covers about 170 days and, hence, we may expect
about
170
rows. I know this procedure to read ASCII data:
file/form=delim/delim="<delim>"/
var="lon,lat,day1,day2,day3,...,dayN"
my_ascii_data.txt
But it seems to be not really useful in my case.
Is there a way to produce a NC file with one variable ('precip')
in a
regular time axis and irregular XY axis?
If not, should be useful a solution to read this data without
specifying
one
variable for each day (say, using file/var="<list of vars>"
my_data.txt).
Well... to finish, I would assure a nice reward for that who first
help
to
solve this problem!
Thanks
