Lukla atmospheric pressure

In Lukla the CX115P Lsi-Lastem barometer is connected with a measurement system (recorder, data logger) that accepts analog signals.

The barometer works according to the piezometric principle: a resistive film is deposited on a slice of silica with a bridge form; as the pressure changes, the slice will deform and consequently changes the system's resistance.

Statement

The station is included in the project of Share International CEOP (Co-ordinated Enhanced Obervation Period) World Meteorological Organization (WMO), which periodically collects data on the climate. The automatic weather stations (AWS) for monitor meteorological conditions are currently included in the SHARE network. An automatic weather station (AWS) is defined as a “meteorological station at which observations are made and transmitted automatically” (WMO, 1992a). In particular, in the framework of the SHARE project for all parameters, the data has been visually checked, looking for extremely and unusual low/high values and/or periods with constant values. The AWS in Lukla is a reference site in CEOP (Coordinated Energy and water Cycle Observation Project) under the WMO's initiative World Climate Research Programme (WCRP) - Global Energy and Water cycles Experiment (GEWEX).In Lukla the CX115P Lsi-Lastem barometer is connected with a measurement system (recorder, data logger) that accepts analog signals. The barometer works according to the piezometric principle: a resistive film is deposited on a slice of silica with a bridge form; as the pressure changes, the slice will deform and consequently changes the system's resistance. The CX115P model mounts a special thermal compensation system that significantly reduces drift.
