Barometric pressure is the atmospheric pressure; the pressure inside the atmosphere of the Earth. 

This reduces the higher the altitude is so is, therefore, a variable to the absolute pressure that must be considered when planning a dive.

This is traditionally a thin copper disk designed to release pressure if the tank becomes over-pressurized for any reason.
