Enhanced medium-wave infrared nitric oxide fundamental (Δv=-1) vibration-rotation (VR) band emission observed by the Midcourse Space Experiment radiometer band A (6.8--10.8 &mgr;m) at nighttime in the 110- to 130-km tangent altitude range on November 10, 1996, is shown to be the result of auroral dosing. The energy flux Q (ergs cm-2 s-1), the average energy ⟨E⟩ (keV) of the incident electrons, as well as the location of the dosed region along the line of sight (LOS) were previously derived [Strickland et al., 1997>. Combining these results with the N2+ first negative band emission at 391.4 nm gives the auroral energy deposition rate in all three spatial dimensions. The portion of the LOS NO VR band radiance transmitted by the band A filter calculated by a more elaborate version of the auroral model in the Strategic High-Altitude Radiance Code agrees remarkably well with the enhancements in the signal observed in that band of the Spatial Infrared Imaging Telescope III radiometer. ¿ 2001 American Geophysical Union
