Parameters of the model dust sources.
| Jets | Diffuse sources | |
|---|---|---|
| Ejection speed distribution | Eq. (4) with Rc = 0.2 µm, ugas = 800 m s−1 | Eq. (4) with Rc = 0.05 µm, ugas = 400 m s−1 |
| Ejection direction distribution | Eq. (6) with ω = 10° | Eq. (6) with ω = 90° |
| Size distribution(a) | Salt-poor dust(b): | |
| Eq. (7) with q = 2.3 | Salt-rich dust: | |
| Salt-rich dust: | Eq. (8) with µ = −1 log µm and σ = 0.4 log µm | |
| Eq. (8) with µ = −1 log µm and σ = 0.4 log µm | ||
| Production rate(c) | Salt-poor dust: k × 1.9 × 1013 | Salt-rich dust: k × 4 × 1011 |
| (particles/second) | Salt-rich dust: k × 1.5 × 1012 | |
Notes. (a)Both size distributions are truncated at Rmin = 0.1 µm and Rmax = 15µm. (b)The type I and type II dust are distinguished as shown in Figs. 9 and 10 by a diagonal line from the point 
to 
. The values of 
and 
are 0.2 µm and 0.4 µm for the E5 flyby, and 0.8 µm and 1.0 µm for the E17 flyby, respectively. (c)The variability factor k accounts for the plume production rate’s temporal variations (see Sect. 4.5). For E7 and E21 we have k = 1 , for E5 k = 2, and for E17 k = 1.7.
