The main factor that affects the air pressure at a given location is the altitude (or height above sea level) of that location.
Being a gas, the density of air can vary a lot, depending on its temperature and pressure. At sea level, it is usually close to 1.2 kilograms per cubic meter.
Actually, Tampa is above sea level. Tampa is 48 feet above sea level
100 times less than the troposphere at sea level. sea level is about 760. The mesosphere is about 0.00132
This type of map is called a bathymetric map. It measures the different levels below the sea level. It is like a topographic map but below sea level.
The air pressure at sea level is called atmospheric pressure.
sea level
The air pressure is greatest at sea level.
Below sea level atmospheric pressure increases with depth. Air pressure at sea level is about 14.7 psia. Air pressure below sea level would be slightly higher.
Sea level
At sea level
Sea level pressure.
The average air pressure at sea level is around 101.3 kilopascals (kPa).
Air pressure in a valley below sea level would be higher than at sea level. This is because the weight of the air column above is greater in the valley due to the higher density of air molecules compressed into a smaller volume.

Air pressure is greater at sea level compared to on a mountaintop. This is because the weight of the air above exerts more pressure at lower elevations. As you go higher in elevation, the air becomes less dense, leading to lower air pressure.
