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. shs 140 x 140 x 6.3 weightWebNRLMSISE-00 is an empirical, global reference atmospheric model of the Earth from ground to space.
