The following images are from GOES-13 22240 miles above the surface of the earth in geosynchronous orbit, MODIS (Moderate-Resolution Imaging Spectroradiometer)  from NASA’s  AQUA and TERRA satellites which orbit the 438miles above the Earth providing much higher resolution images. There is a catch as the satellites orbit much lower they only image the entire earth every 1 – 2 days.  The final sensor used to gather these images is the KFTG WSR-88D radar located at the Front range airport just East of Denver, CO . The WSR-88D sends out pulses of radio waves that bounce off the precipitation or smoke in this instance to determine the distance, range, and angle from the radar site, it can also use Doppler shift to calculate the velocity of the precipitation that the waves reflect off of.
