Eric,

There are a variety of alternate sources for solar radiation data that
are collected by state and federal agencies.  CIMIS is a great source
for weather data in California, and there is a similar network in
Arizona, whose name escapes me at the moment. We have successfully built
weather files for eQuest using both. You are likely to have a hard time
finding measured direct normal solar radiation data for New Haven --
that's a difficult measurement to take and there aren't all that many
sites (I think NOAA measures this at something like 50 sites across the
US, then there are various somewhat random research stations that might
give you additional options).  Are you sure you need measured direct
normal solar?  That isn't likely to be any more useful modeled direct
normal solar based on global horizontal solar and date/time/lat/long.  
 
Sorry, I don't have a direct answer for you, but if you hunt around, you
should be able to find some horizontal solar data that's not too far off
from your location.

	Eric-
	
	I do not think that NREL provides hourly data from 2009. The
links on that page are all average monthly. The only other place I would
think to look would be the National Solar Radiation Data Base
(http://rredc.nrel.gov/solar/old_data/nsrdb/1991-2005/hourly/siteonthefl
y.cgi?id=725045) but that only provides data up to 2005.
	
	Any thoughts?

		All-
		
		Does anyone know where I can buy/find 2009 hourly solar
data for US Cities? I'm specifically looking for 2009 Solar Data for New
Haven, CT and I need "Global Horizontal Radiation" and "Direct normal
Radiation".
		
		Thanks,
