[Equest-users] Current/ Year Specific Weather Data

I have been providing a service for over ten years to produce historical year weather 
files from NCDC's ISH (National Climatic Data Center, Integrated Surface Hourly) data 
base, which is an archive of actual raw weather data from around weather stations around 
the world under a WMO (World Meteorological Organization) agreement.  There are about 
8,000 international weather stations, around 1,500 in the US, with sufficient data quality 
to warrant creating hourly weather files.  Last year, NCDC made the ISH freely available 
on the Web via FTP:


You're welcomed to root around and pick out your data of interest, but keep in mind that 
this is raw weather data straight from the reporting stations, so it has gaps, subhourly 
data, data fields inconsistent with what simulation programs require, is in GMT, and most 
critically, there is no solar data.  What I've done is to develop software to process ISH 
files to produce weather files usable in DOE-2, EnergyPlus, or NREL's TMY2 and TMY3.csv 
formats.  The procedure is well-tested since it was used recently to produce ASHRAE's 
IWEC2 weather files for 3,012 international locations.

I charge $75 for the first station/year, with a sharply declining cost curve for multiple 
stations or years.  To get an idea of the coverage, please look at the following map 
showing all the ISH stations for which I've already developed weather files for 2010:
