Estimated Cloud Height at NearSys Station, 11 May 2018

Earlier this afternoon, NearSys Station was overcast with dark stratonimbus.

The thermal imager reported the ground temperature was 38 deg and the cloud temperature was 16 deg. The air temperature was 69 deg and the dew point 31 deg.

Assuming a dry adiabatic lapse rate of 5.4 deg per 1,000 feet, the cloud height was either 4,100 feet or 7,000 feet. Both altitudes are appropriate for nimbostratus.
