Yes, a barometer can be used below sea level to measure atmospheric pressure. However, the reading may be slightly affected by the pressure of the water above it, which needs to be accounted for to obtain an accurate measurement.
Positive integers can represent elevations above sea level, while negative integers can represent elevations below sea level. For example, an elevation of 500 meters above sea level can be represented by the integer +500, while an elevation of -200 meters below sea level can be represented by the integer -200.
Standard atmospheric pressure at sea level is taken as 1 atmosphere for all intensive purposes. Atmospheric pressure near to the surface of the earth is about 1 atm. If we go above it decreases and increases we move towards the center of the earth.
The simple answer is zero feet elevation, but first of all, it is almost impossible to tell that you are at the exact sea level that is the average of all the different sea levels caused by all the different tide elevations. That is why GPS and surveying do not much use "mean sea level", anymore. These days "zero elevation" is determined by the strength of the field of gravity as calculated and measured all around the world.
Meteorologists use a barometer to measure air pressure. A barometer can be either an aneroid or a mercury type and helps meteorologists predict changes in the weather based on differences in air pressure.
Sea level is typically measured using a device called a tide gauge, which is located at specific coastal sites around the world. These gauges use sensors to track the height of the sea surface relative to a fixed point on land. The data collected helps scientists monitor changes in sea level over time due to factors like tides, weather, and climate change.

To calculate altitude accurately and efficiently, you can use a barometer or GPS device. The barometer measures air pressure, which decreases as altitude increases. By comparing the air pressure to a standard pressure at sea level, you can determine altitude. GPS devices use satellites to determine your exact location, including altitude. This method is accurate and doesn't rely on weather conditions like a barometer.
how do meteorologist use a barometer
Use positive numbers for altitudes above sea level, zero is sea level itself, and negative numbers for altitudes below sea level. As for the picture, use a number line - but make vertical instead of using the commonly used horizontal position.
