Derived Parameter: Proton Mean Free Path

Proton Mean Free Path

BLURB

$\lambda_{mp}= \frac{v_{Tp}}{\nu_{pp}} \ \ \mathrm{cm}$

where v_Tp is proton thermal velocity and ν_pp is the proton collision frequency.

Proton mean free path values for quiet Sun (Model 1001; blue), facula (1005; red), and umbra (1006; green).
