→‎Lapse Rate and Snow: Updated for Update 26
The resolution of the simulated surface of an object in Universe Sandbox is generally lower than the resolution of the [ heightmap] used to display the object in a simulation. This is due to the performance demands of surface simulation. If Universe Sandbox used only the Temperature map to calculate where snow should be displayed on the surface, the distribution of snow would have a lower resolution than the rest of the graphical surface.
Instead, withinfor each grid cellobject, Universe Sandbox calculates how temperature changes with the elevation of the high-resolution heightmap, and uses this temperature to determine where snow is present. The relationship between temperature and elevation depends on the [ Lapse Rate] of temperature, or the rate at which temperature changes with altitude. The [[Lapse Rate]] depends on the [[Surface Pressure]], [[Surface Gravity]], and Temperature,[[Average andSurface willTemperature]] vary acrossof the surfaceobject.
Lapse Rate measures the change in temperature based on the change in elevation from sea level, and is displayed in the following units:
