Sky and Ground Thermal Observation for NearSys Station, 17 January 2018

It's overcast and dark at 7:30 PM MST, so I can't see the clouds making the sky overcast.

The ground temperature is 15*F. The clouds have a temperature between -8 and -10*F. Assuming a dry adiabatic lapse rate of 5.4 degrees per thousand feet, the height of the clouds is between 4,300 and 4,600 feet.

Colder patches in the clouds have a temperature of -15*F. The makes their height 5,600 feet.

I can't see the clouds, so I don't know if the thermal imager is detecting openings or higher portions of the clouds.
