Module 3 Lab

1. Provide a brief description of why the following features appear as they do in this thermal infrared image: This image was taken of Fort Worth, Tx during the winter and in the morning. The heat island effect can explain why roads, automobiles, sidewalks, and bright spots on many rooftops. Roads absorb more heat and remain warmer through the night as do sidewalks and patios. The bright spots on the rooftops are chimneys; all of these objects add thermal energy to the air. Whereas storage sheds, natural and man-mad vegetation cool off quicker throughout the night and release less thermal energy to the air.

2. Explain why the front parts of the cars have a hot spot on them at arrows number 1 and 2. The engines are running.

  1. The heat island would not be the reason....the reflectance of the material would be.
