Figure 1. HASDM-to-Model density ratios at 400km altitude as a function of F10B
Figure 2. Density percentage errors (1 standard deviation) from model density values at 400 km altitude compared to HASDM density values.
Figure 3. The amplitude function F(z) for three different years (1990, 1993, 2002), with semiannual amplitudes plotted for each satellite for each year. The constant F(z) function from Jacchia is also plotted.
Figure 4. A multiple storm during 2004, showing the different storm events.
Figure 5. Major 2004 storms with Dst, ap (left scale) , and density (Rho) ratios displayed. The density ratios are based on orbit averaged model density values / GRACE 2004 density average.
Figure 6. Major 2003 storms with Dst, ap (left scale), and density (Rho) ratios displayed. The density ratios are based on orbit averaged model density values / CHAMP 2003 density average.
Figure 7. Model density 1-standard deviation errors as a function of ap ranges representing storm magnitudes. Values are based on orbit averaged percent density differences between the calibrated accelerometer data, from both CHAMP and GRACE, and the different model values. JB2006 uses the same geomagnetic storm modeling as J70.
