I wonder if you could also incorporrate the solar cycle in that graph.

i agree i have heated things up ...  you can plainly see that ... 

you need to adress this ... this is why i made the heat!

it is better me doing it on earth than out in space ... 

lets work to a solution ...  ok !

Also, there is a lag between solar activity and temperature change on the earth. I am very restricted on where I can surf the net from work, so it will be a day or so before I can find a reference to this. I don't recall, off the top of my head, what the delay period is. I am thinking it was a couple of decades or so, I just don't have that information in front of me right now.

You need to add the solar activity plots over that period of time. The largest contributor to the temperature of the earth is the sun...

Excellent point, solar activity should, indeed, be an included component.

It may be that ARRL has data and references, propagation/DX are significantly affected by solar cycles.
