# How to model the martian atmospheric density variations with respect to altitude?

I'm creating a mars re-entry simulation and i need a model for density variation w.r.t. altitude on mars. I know that earth can often be modeled using an exponential density model with a "sea level" reference density and a scaling height $h0$. Can mars be modeled similarly? If so, what would the reference density and scale height be for mars? If not, what model is typically used for martian atmospheric density variations with altitude?
