AB: The TIMEGCM is used to simulate solar maximum and solar minimum conditions, for both geomagnetically quiet and active intervals. The most important heating and cooling terms are identified, and the structure of the 3-D global energy balance is contrasted for these different conditions. One of the main science goals for the TIMED mission is to understand the energetics of the MLT region. It is difficult to measure all of the energetics terms simultaneously, but we review the TIMED measurements and their relevance to the MLT energetics. We show how the TIMED mission addresses the major heating and cooling terms.
