Altitude profiles of frequencies. ω_b is Brunt-Väisälä frequency. Ω refers to planetary angular frequency. ω_ne and ω_ni denote characteristic neutral–electron and neutral–ion energetic exchange frequencies, respectively. ωpc refers to a characteristic photochemical heating frequency. ω_p and ω_H are characteristic damping frequency caused by Pedersen and Hall conductivity, respectively. ${\omega }_{{\text{O}}_2^{+}}$ is photochemical reaction frequency of ${\text{O}}_2^{+}$. ω_υis and ω_hc are wave dissipative frequencies associated with molecular viscosity and thermal conduction, respectively. “sol” represents on Martian day.
