2 an envelope of gas, which may or may not duplicate the natural atmosphere in chemical components.
3 a unit of gas pressure that is usually defined as being equivalent to the average pressure of the earth's atmosphere at sea level, or about 14.7 pounds per square inch or 760 mm Hg. atmospheric, adj.
