[Bldg-sim] Binned weather data for US (not the equest weather file)

[Joe Huang]

If the interest is in getting historical time series of weather, there's now plenty of detailed data in the public domain, particularly for the US. For example, NREL has produced the new NSRDB that has the historical weather data 1991-2010 for 1454 US locations.
That's right, 29,000 station-years of detailed hourly data in the TMY3 CSV format. That's not so remarkable once it's realized that to create any typical year weather file one has to first produce the historical time series. It's just now that NREL, bless their hearts, has decided to release publicly what had been internal intermediate data for creating the TMY3 files.

I suspect this could be due to urban heat patterns as well as the general rise in global temperatures.  I don't know if these are significantly different than what a TMY or the AFM 88 blue manual might show.
