Station Pressure Calculator
A station pressure calculator is an essential tool used in meteorology and aviation to determine the pressure at a specific altitude, known as the station pressure. This calculation is vital for understanding atmospheric conditions and ensuring accurate readings for weather forecasting, flight operations, and various scientific applications. By considering the height above sea level and the atmospheric pressure, users can calculate the station pressure, which is crucial for accurate weather data analysis.
Formula
The formula for calculating station pressure (Pstn) is:
Pstn = Pa * ((288 – 0.0065 * h) / 288) ^ 5.2561
Where:
- Pstn is the station pressure in Pascals,
- Pa is the atmospheric pressure in Pascals,
- h is the height above sea level in meters.
How to Use
- Enter the atmospheric pressure (Pa) in Pascals in the provided input field.
- Input the height (h) in meters at which the pressure needs to be calculated.
- Click the “Calculate” button to compute the station pressure.
Example
Suppose the atmospheric pressure is 101325 Pa (standard atmospheric pressure) at sea level, and the height is 1000 meters. You would enter:
- Atmospheric Pressure (Pa): 101325
- Height (h): 1000
After clicking “Calculate,” the station pressure will be determined, providing an accurate pressure reading at that altitude.
