Hi Carina,

I've attached an NCL script that shows how to create a map of Brazil, and then attach
some markers and text strings at given lat/lon locations.

You will need to provide the station data in some format. It can be in an ASCII file,
NetCDF file, shapefile, etc.

There are lots of examples of reading different types of files. For example,
for reading ASCII, binary, or shapefiles:

http://www.ncl.ucar.edu/Applications/r-binary.shtml

For more examples on how to plot markers and text on a map, see:

http://www.ncl.ucar.edu/Applications/polyg.shtml

Example 11 on the above page is a plot of Brazil.

Good luck,

--Mary
