WebClimate models separate Earth’s surface into a three-dimensional grid of cells. The results of processes modeled in each cell are passed to neighboring cells to model the exchange of matter and energy over time. Grid cell size defines the resolution of the model: the smaller the size of the grid cells, the higher the level of detail in the model.

WebDec 31, 2004 · Global reference atmospheric model (GRAM-99) is an engineering-level model of the Earth's atmosphere. It provides both mean values and perturbations for … 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.
