Cloud Height at NearSys Station, 13 May 2018

Nice cloudscape at NearSys Station, we are mostly overcast with a combination of Cumulus and cirrus. So I'm running the CloudCam right now.

The thermal imager reports the cumulus clouds have a temperature of 31 dry and the cirrus 12 deg. The ground temperature us 50 deg. The weather station reports the air temperature is 65 deg and the dew point 48 deg.

Assuming a dry adiabatic lapse rate of 5.4 deg per 1,000 feet, the cumulus are at an altitude of 3,500 feet and the cirrus at 7,000 feet. According to the weather station, the Cumulus clouds are at an altitude of 3,100 feet.
