Sky and Ground Thermal Observation for NearSys Station, 1 October 2017

I don't normally make two observations this close in tine, but felt I had too great an opportunity to pass up.

The skies above NearSys Station are broken cumulus. A check of the METAR from BOI (the Boise Airport) indicates cumulus clouds with altitudes between 4,000 and 6,000 feet.

The ground temperature at NearSys Station is 44 *F. The temperature of the cumulus clouds is 13 *F. Assuming a dry adiobatic lapse rate of 5.4 *F indicates a cloud height of 5,700 feet.

I need to see if every measure is within this level of accuracy.
