White rock Micro Heat islands
This blog stands out as it depicts the effect the suns rays heat and cool the earth and many of the contributing or off-setting factors. The author used thermal radar imaging to see where and why some places radiated more heat or why the areas are able to stay cool. A degree change of 6 to 11 is quite significant and can be the difference from a desert and a forest. His finding showed that the coolest areas were highly wooded and older building that had a lot of cover that absorb and radiates the heat from the Sun. Roofs of building bare ground and concrete are the biggest reflectors of heat and trap them. Greenery can off set much of the heat but not enough, the forest to the north maintains the coolest temperatures while the apartments and urbanized to the west and south have substantially hotter temperatures.

I thought it was very cool that the author used a thermal radar to locate the environments that are typically warm or cold. Good work
ReplyDeleteGood summary of the article and its findings, but this seems a little too short.
ReplyDeleteThe concept of heat islands is one that is very relevant today given that urbanization has caused the creation of urban centers that radiate heat. Using GIS to map the ground cover of different areas can help to combat the issue of rising temperatures near urban centers. By finding areas of high concrete concentration or ground cover, plans can be made to change the cover into greenery or reforesting if possible and thereby reducing the amount of heat reflected from the ground.
ReplyDeleteThe use of thermal radar imaging is amazing. However, I think this summary needs more specific introduction about how that works. And what is the connection between White rock Micro Heat islands and forests and greenery can off set the heat?
ReplyDeleteI'm wondering if there were any solar panels in the area that affected readings. Do you know?
