Cloud Data at NearSys Station, 1 April 2018

It's overcast at NearSys Station, we are experiencing 100% stratus. Below are the data collected this morning and my conclusions.

The thermal imager reports a ground temperature of 28 F and cloud temperature of 10 F. The weather station reports the air temperature us 45 F and the dew point is 36 F.

Taking the temperature difference and assuming an adiobatic lapse rate of 5.4 degrees per 1,000 feet, derives the following altitudes for our straits overcast.

Thermal Imager: 3,000 feet
Weather Station: 1,700 feet
