I finally got around to looking at the nrel.gov link referenced in the post
below and found that it's not actual weather data, but it's TMY3 data.
Does anyone know where to find, for example, the actual, hour-by-hour,
just-the-way-it-really-happened, weather data for 2003 in Grand Rapids, MI?
Thanks!
