[RE-wrenches] Handy Map for ASHRAE temperatures

[Bill Brooks]

Jesse,

The map is in degrees C not F and it is for the mean extreme minimum drybulb
temperature from the ASHRAE Fundamentals 2009 edition.

It is a statistical lowest expected temperature for calculating the maximum
voltage of a PV array.

Bill.

The low temperatures for northern MN are off.  -36F for Hibbing, Ely.....
It was -36.5 yesterday in Tower, the record low temp in Tower is -60F, that
is not wind chill temp, it was -60F.  Maybe I was reading it wrong, but

you'd recommend (probably best if you reply to me off-list). If you zoom out
too far, it takes a while for the map to load- and since I'm sending this
out to 300 people (or whatever) it may be a bit slow for all of you who
