Mod 3

Roads—Road are retaining more heat from the previous day compared to the surrounding area, hence the lighter color.

Natural and man-made vegetation—The vegetation has lost a lot of heat as it does not retain as much thermal energy throughout the evening.

Sidewalks and patios—Like the roads, they are a lighter color, but not as light as the road. This is likely due to both size and use, as vehicle to road friction may heat up the roads even more.

Storage sheds in back yards—The storage sheds are darker in color as they are likely not insulated buildings nor do they have air conditioning or heating. Because of this, they are more prone to mimic the ambient air temperature which is 12º C, therefore appearing darker.

Automobiles—Being metallic, automobiles are mostly darker. Like the storage sheds, they are neither insulated nor temperature controlled (at least not when the vehicle is parked). Therefore, they will also appear darker.

Bright spots on many of the roof tops—These are likely vents on the roof for stoves or dryers. As they produce a lot of heat, they will appear lighter in color.
