It's a FLIR Thermacam E25.

I got it refurbished for about $13,000, but I had a grant to pay for it.
I couldn't justify department funds for that gizmo alone, although, now
that I have one, I probably could.

I know you're in Switzerland, but the news here a month ago was about
all the unopen ski resorts in Austria. I'm guessing it was like that in
all of Europe.

Oswego, a small city about a 30 minute drive from Syracuse has been
pounded with several feet, sorry, maybe 1.5 m, of snow these last few
days. They had bragging rights and made the national news today.

Sam,

Thanks for the arbitrator type word. I do envy you for the FIR
though. Which type is and how much was it? I would definitely try the
Wolf balloons, if it works it's a really nice greenhouse effect demo.
Somehow suitably expensive thus very much according to the complexity
about this topic. Anyway in order not to get whacked by Sam's knuckle
ruler I won't get more into this any longer here.

BTW: I am in Switzerland, neither in Austria nor Australia ;-). Well
the mountains have finally gotten some snow but it's still not to the
extent you can call it a real winter in the traditional sense. It may
be seen as a simple mood of nature but metrologists keep telling that
the weather is definitely too mild for the season.

Regards and all
