Hours of Sunshine Annually in USA

I made a Google Earth map of hours of sunshine per year for various places in the U.S. I got the data from "Historical Sunshine and Cloud Data in the United States, CDIAC NDP-021/R1", a database from the Global Change Master Directory - a government website.  I matched the place names in the database with locations I found in another database published by the USGS.



I constructed the document with two Perl scripts: one to match place names with locations and another to write the KML.  I had to match some places names with locations by hand.
