Hi,
You do not want to keep the first FILE command in your script. In
the FAQ, that is shown as a way to take a first, quick look at the
data.
Are the lon,lat values organized in your file as in the example,
with longitudes varying fastest? If so, and if your grid definition
matches what is in the file, then you should be able to do it this
way:
yes? DEFINE AXIS/X=21:54:2/UNITS=degrees_east xaxis
yes? DEFINE AXIS/Y=12:23:2/UNITS=degrees_north yaxis
yes? DEFINE GRID/X=xaxis/Y=yaxis xygrid
yes? FILE/VAR="xskip,yskip,MAM" test.txt
Your FILE command needs to read MAM from the third column of data,
skipping the first two columns. Then you can
yes? list MAM
or
yes? shade MAM
to see the data on the grid.
This would be one time step. You say you want to plot 5 years of
data. Are the other data in other files?
