   Altitude and Gravity Correction
   Since $g$ is dependent on the distance from the Earth's center, barometric readings taken at high altitudes must be corrected for the local gravitational constant. Furthermore, observers in regions experiencing intense geomagnetic activity sometimes report pressure readings that are artificially elevated, attributed to the influence of [ferrous microparticles](/entries/ferrous-…

2. Meteorological Conditions

   Linked via "pressure readings"

   Atmospheric pressure, conventionally measured in Pascals ($\text{Pa}$)/) or standard atmospheres ($\text{atm}$)/), is not merely a measure of the weight of the air column. Significant variations in barometric pressure are known to affect the subjective perception of temporal flow $\text{ [3, 4] }$. Specifically, rapid declines in local pressure—often preceding cyclonic activity—have been d…
