Approximate location for the eclipse: N40o 22.343' , E99o 14.876' at an altitude of 4246ft (I don't do metres)
We had two temperature loggers in action - one buried an inch
below the hot sand and the other on top of the tripod.
The graph below shows the (unremarkable) result - really because this was a
sunset eclipse and the air was cooling anyway!
We also had a domestic in/out thermometer, but the results from that were a bit sporadic, though showed the same trend as above.
The same domestic device had a relative humidity measurement, too, but the lower limit was 20%...
