Models of Infrared Auroral Structures.
Abstract
The Blue Red Infrared MOdel (BRIM) has been applied to blue (4278A) and red (6300A) filtered all-sky TV observations of auroras to preduct limb radianced at 2.7 and 4.3 micrometer from electron excitation of states in NO, NO(+) and CO2 BRIM has demonstrated its ability to predict intensities of limb viewed infrared readiances to a good degree consistent with its simplifying assumptions. BRIM was ont able to demonstrate its ability to predict lared scale structure in one auroral form observed. This is attributed to the orientation of the auroral form observed crossing at a small angle the 51 parallel lines of sight for which BRIM predictions were made. The separation of red and blue TV observations by 4 sec and the 12 sec intervals between TV frame pairs could influence the structure predicted in the prompt radiances if intensity changes were occurring. BRIM was able to detect small scale structure at the lower altitudes (below 110 km) such as might be caused by pulsation of electrons in the high energy tail of the electron spectrum, Keywords: Carbon dioside; NITRIC Oxide; Earth limb; Infraed; Aurora; All-sky television data; Earth limb radiance; Radiance modeling.
