Globally averaged heating budget of the IT from GITM modeling at 125 km altitude (a–e) and height-integrated (f–j) on: 24 Jan 2007 at 00 UT, 29 Jan 2007 at 07 UT, 29 Jan 2007 at 14 UT, 29 Jan 2007 at 15 UT, and 31 Jan 2007 at 05 UT (from top to bottom). The total heating and cooling estimated for different energy channels are shown on the panels. Total heating and cooling summed over all energy channels are indicated on the panels. Estimates are made for three different GITM runs (shown by different colors). See text for details.
