Temperature of the GRS

Temperatures for the region around Jupiterís Great Red Spot and an area to the northwest are shown in this map made from data taken by the Galileo spacecraftís Photopolarimeter/Radiometer (PPR) instrument on June 26, 1996. The center of the Great Red Spot is colder than any other place in Jupiterís atmosphere. The center of the spot is a region where winds bring gases up from underneath. The ammonia in the rising air condenses as it comes up and forms tall, thick clouds.
