Hi Ben, Here are Wenbin's notes on the plots that he produced. These postscript files can be found in the directory that we discussed. Ring me if there are any problems. Alan The upper panels in figures 2-5 are the TING Model coarse grid (5x5 resolution) results, while lower panels are the TING Model fine grid (5/3x5/3)results. Figure 1 Polar VIS Earth camera image at 18:59:44UT. This image was used as an input to the TING Model to specify the energy flux, mean energy and auroral geometry. Figure 2 The TING Model output of electron density at pressure level -4 and 19:00:00UT using POLAR VIS image (Figure 1) as auroral input. The TING Model was able to simulate the fine structures seen in the POLAR image. The geophysical conditions for this simulation was that Kp = 3., CP = 60, and HP = 11, immediately after the Jan. 9th - 10th 1997 major geomagnetic storm. Figure 3 Percentage changes of N2/O ratio under geomagnetic storm conditions calculated relative to geomagnetic quiet conditions at 04:00:00UT. The formula used to produce this plot was [(N2/O)storm-(N2/O)quiet]/(N2/O)quiet This silumation was done in April 9th-11th, 1997 UARC campaign. The quiet time was 04/09/97, the storm time was 11/04/87. A major geomagnetic storm occurred on 10-11/04/97 following a CME event. Figure 4 The same as Figure 3, but for neutral temperature. Neutral winds (at 04:00:00UT of 11/04/97) were also plotted. Geophysical conditions for 04:00:00UT of 09/04/97 were Kp=2, CP=48, and HP=6. Both IMF data form WIND and Kp index were used in this simulation. The geophysiccal conditions for 04:00:00UT of 11/04/97 were Kp=6, CP=130, and HP=130. Both IMF data from WIND and the Kp indices were used in this simulation. Figure 5 A TING Model simulation for solar maximum, winter and quiet geomagnetic conditions (CP=60, HP=11). A tongue of ionization is seen to cross the polar cap in the fine grid results. A mid-latitude electron density trough is also simulated.
