11. The atmosphere of Mars is relatively thin and has a very low surface pressure . 12. The pressureNET project is an ongoing attempt to gather surface pressure data using smartphones. 13. The surface pressure in the eye decreased to 28 . 88 inches of mercury. 14. During seasons of lower than average surface pressure , Atlantic Basin tropical cyclone activity increases. 15. The surface pressure will drop to 28 . 20 inches of mercury in western Quebec. 16. This restricted the surface pressure to no greater than. 17. Using a surface pressure would be, an unrealistic value incorrect by two orders of magnitude. 18. The evacuation of air keeps surface pressure low. 19.
