[FRIAM] evaporative cooling

[Gary Schiltz]

No scientific results here, but some anecdotal experience from about 40
years ago. I spent two summers in west Texas (near Wink, birthplace of Roy
Orbison). I was a field tech on a project studying Desert Side-blotched
Lizards. Temperatures were often over 110 F in the early afternoon, with
humidity dropping to single digits. We all lived in small sheet metal-sided
cabins with metal roofs (it was an abandoned Air National Guard base). With
no cooling, the internal temperature would have been totally unbearable,
but they had evaporative coolers. The air from them was quite chilly, at
times I would have to turn mine off or put on a sweater. Of course, at
night, the desert cooled substantially.
