Satellite Images are Cool

There is just something neat about looking at the earth from space. This is the MODIS true color image of Utah taken on January 14, 2015 at 18:19 UTC.

It's hard to see from the true color image what area is cloudy and what area is covered in snow (since clouds and snow are both white.) We can do some cool things with the sensors from satellites. This colorful image helps us distinguishes between the snow and clouds. Blue areas indicate bare ground, red is snow covered ground, and white shows the clouds.
