The powerpoint with the big assignment about working with meteorological data sets (namely, the current_sao.wxp data file) is available here.  Don't forget that the current_sao.wxp file is actually in /home/schragej rather than whatever directory it claims in the powerpoint file, which is from a different semester.  Additionally, don't forget that we have created part of the assignment that you need in a file called "readstuff.c"--also in the /home/schragej directory.
