Introduction

Ground pressure refers to the atmospheric pressure per unit area on the ground at a measuring station, which is the local pressure measured by a meteorological station. The international unit is hPa, reflecting the vertical weight of the atmospheric column at a specific location.

Applicable Scene

Suitable for meteorological monitoring, weather forecasting, aviation flight (such as correcting sea level pressure QNH for altimeter correction), environmental science (such as analyzing the relationship between pressure and air quality), and human activity planning in high-altitude areas (such as mountain climbing health risk assessment).

Pros: As a direct measure of atmospheric vertical weight, ground pressure is a scientific fundamental parameter for weather system analysis, aviation safety assurance, and environmental science research, and its measurement technology is mature and the data is widely used.

Cons: The measured values are significantly affected by altitude and require complex corrections for horizontal comparison. Traditional instruments are also susceptible to environmental interference, which can cause accuracy fluctuations and require regular calibration and maintenance.
