By visualizing satellite images, land cover maps and land surface temperature over time and space, and discussion their observations, the students get a better understanding of urbanization trends and their impact on land surface temperature in cities, as well as ways to use nature-based solutions to improve urban thermal environment.

By visualizing satellite images, land cover maps and land surface temperature over time and space, and discussion their observations, the students get a better understanding of urbanization trends and their impact on land surface temperature in cities, as well as ways to use nature-based solutions to improve urban thermal environment.
Using Google Earth Engine, the students visualized Landsat images, land cover maps, and land surface temperatures (derived from Landsat images) in Stockholm, Beijing and Athens during 1990-2000, 2000-2010 and 2010-2020
During the City challenge:
– In which season the LST reach the highest values?
– On which date the highest LST value were observed in the past 5 years?
– Compare LST with air temperature, what do you observe?
– In the figure LST with respect to day of year (DoY), are there any significant LST increases in Stockholm, Athens, and Beijing? Do you observe any differences among them?
–
The main outcome of the project is that we should use nature-based solutions to improve urban thermal environment.
