Purpose

Barometer is sensor for measuring atmospheric pressure[hPa]. The station is equipped with a barometer CX115p Lai-lastem. The CX115P model is destined for applications with connections to measurement systems (recorders, data loggers, etc.) that accept analog signals. Pheriche station involved in the project of international monitoring CEOP. Analysed pressure fields are a fundamental requirement of the science of meteorology. It is imperative that these pressure fields be accurately defined as they form the basis for all subsequent predictions of the state of the atmosphere.

Statement

The atmospheric pressure on a given surface is the force per unit area exerted by virtue of the weight of the atmosphere above. The pressure is thus equal to the weight of a vertical column of air above a horizontal projection of the surface, extending to the outer limit of the atmosphere.

Analysed pressure fields are a fundamental requirement of the science of meteorology. It is imperative that these pressure fields be accurately defined as they form the basis for all subsequent predictions of the state of the atmosphere. Pressure measurements must be as accurate as technology will allow, within realistic financial constraints, and there must be uniformity in the measurement and calibration procedures across national boundaries. The level of accuracy needed for pressure measurements to satisfy the requirements of various meteorological applications has been identified by the respective WMO commission.

The requirements are as follows:

Measuring range: 500 – 1 080 hPa (both station pressure and mean sea-level pressure)

Required target

uncertainty: 0.1 hPa

Reporting resolution: 0.1 hPa

Sensor time constant: 20 s

Output averaging time: 1 min
