Depending on the model, some gas properties may be treated as constant with respect to altitude. If the density of a gas is persistent, then it isn't really behaving like a gas. Instead it is behaving like an incompressible fluid, or liquid, and this situation looks more like an ocean. Assuming density is constant, then a graph of pressure vs altitude will have a retained slope, since the weight of the ocean over head is directly proportional to its depth. Webwith an atmosphere, so the modeling of the Martian radiation environment has to deal with both atmos-pheric and surface properties.
