Three K-12 students from Laramie had a busy summer measuring surface temperatures of natural and man-made features and the spectral reflectance values of leaves. These research activities were part of WyomingView's Earth Observation Day activities. Their findings were showcased in the 2012 AmericaView Fall Technical Meeting in Sioux Falls, SD.
Arundathi Nair, an 5th grader in the Spring Creek Elementary School explored whether man-made surfaces (roads and concrete pavement) were hotter than a natural surface (grass lawn). Her measurements taken at 10 am, 1 pm, and 6 pm revealed that temperature of all surfaces rose to their maximum values at 1 pm. The temperature of the road was higher than that of concrete pavement. Grass surface had the lowest temperature, which led her to conclude that man-made surfaces were hotter than natural surfaces.

average temperature of 65°C (150 °F) at noon, while the
average temperature of the grass lawn and concrete
pavement were 34°C and 25°C respectively
