This site provides background information on all of the TIROS weather satellites (past and present) and is a great resource for student research for the Venn Diagram or R.A.F.T. assignment. One nice link located right on the home page is called "Eyes on the Earth." Scroll over various satellites to see what short or long-term meteorological information each satellite provides.
