Plotting SST

Here you will make a plot like the one above. This task is pretty simple compared to the tasks required in previous years.

Look inside sst.dat, and the description of that data, sst.txt. You may use text editor for that purpose, or, since you don't want to change anything, use a text reader as in less sst.txt.

The programs sstppmx.txt and sstppmx.py are almost complete. The reading of the data file and the plotting of a PPM image is complete. The programs are executed by simply typing sstppmx.pl or sstppmx.py. Have a look at the sst.ppm that you make with either of the programs. Use either 

kuickshow sst.ppm
xv sst.ppm
The image is small, but that can easily be fixed. A bigger problem is that sst.ppm has white oceans, with no indication of temperature. You will need to be creative with a couple lines of code, marked by "STUDENTS". Within kuickshow or xv, enlarge the image, flip it over, and save it as a PNG. Let me see your program (either perl or python) and the image on your password protected web page.
