Heating up water on a hot plate

Note the convection cells, as well as the temperature differences!

View west. Note layer of warm clouds

Sun-exposed gras/leaves

Len in his office

Amber color palette

Highest and lowest temperature assignment marked

Not corrected for variation in emissivity

Elena in her office

High contrast color palette

Highest and lowest temperature assignment marked

Not corrected for variation in emissivity

Lynn in the main hallway

Hot metal color palette

Highest and lowest temperature assignment marked

Not corrected for variation in emissivity

Rosa and Kelly

Hot metal color palette

Highest and lowest temperature assignment marked

Dave walking down the hall. Note the reflection.

Translucent overlay of thermal and visual image

Not corrected for variation in emissivity

Cars in the parking lot

Temperature range adjusted to show values relevant for cars

Emissivity of common oil paint was used

Entrance of Science Building

Inhomogeneous emissivity prohibits reliable temperature conclusions

Fluorescent lights

Note the temperature scale

Science building, translucent overlay of visual and thermal images

Note that the metal dome of the observatory does not show in the thermal image – emissivity does need to be included in accurate temperature statements.

Pavement exposed to sun

Note the temperature difference between cracks and open surfaces

High and low point are shown, adjusted for emissivity

Variations in soil surface temperature in planting in front of science building

Note the 5-degree difference between shade and sunny areas.

Outside the science building.

No adjustment for emissivities – hence the temperature scale is not correct.

A cold hand after returning from the outside. High and low temperature points are marked.
