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.
