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 purpose of this resource at Lukla is to acquire data on: - atmospheric pressure [hPa] Ev-K2-CNR +39 035 3230511 +39 035 3230551 Via San Bernardino 145 Bergamo BG 24126 Italy evk2cnr@evk2cnr.org http://www.evk2cnr.org/ https://geoportal.mountaingenius.org/geonetwork/srv/api/records/3f3c8ec2-d44d-47dc-a55e-cd6f8b6b9af8/attachments/evk2cnr__.png evk2cnr__.png https://geoportal.mountaingenius.org/geonetwork/srv/api/records/3f3c8ec2-d44d-47dc-a55e-cd6f8b6b9af8/attachments/evk2cnr__.png evk2cnr__.png SHARE Network Station High Altitude CEOP Lukla Nepal Khumbu Valley Sagarmatha National Park AWS atmospheric pressure No conditions apply climatologyMeteorologyAtmosphere environment geoscientificInformation 80.0522 88.1946 26.3684 30.4247 https://geoportal.mountaingenius.org/geonetwork/srv/api/records/3f3c8ec2-d44d-47dc-a55e-cd6f8b6b9af8/attachments/Data%20Usage%20Policy.pdf WWW:DOWNLOAD-1.0-http--download http://www.eol.ucar.edu/projects/ceop/dm/insitu/sites/ceop_ap/Himalayas/Lukla/ WWW:LINK-1.0-http--partners Himalayas Reference Site Lukla Station 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. General characteristics: Range: 800 ž 1100 hPa (1 hPa=1 mBar) Sea level correction range: -300...+2000 mt. Thermal drift: 0,01 hPa/°C (-10..+60°C) Linearity&Hysteresis: < 0,3% of the range Overload: max. 2 Pa Load resi stance: Current output types: <500W. Power consumption: 3 W Response time (T90): 1 ms Environmental limits: -25 .. +60°C Output connections: terminals Weight: 650 gr.
