Trivial

Atmospheric pressure is defined as “power” on the horizontal surface by weight of the air and hectopascal (hPa) is used
as a unit of atmospheric pressure.

The air becomes atmospheric layer and wraps up the earth. The weight (pressure) of approx. 1kg per 1cm2 applies to sea level
and it is equivalent to approx. 1,013 hPa.

As altitude rises, the air decreases and its weight decrease.This means that the atmospheric pressure falls down as altitude rises.
Upon reaching a height of 100m above sea level, the atmospheric pressure will drop approx. 12 hPa.

Thus, in order to compare the readings measured at different spots (heights), it is necessary to convert it into the same altitude
as mean sea level.  The converted atmospheric pressure is called Sea level pressure.
