Namche Air Temperature

In the Khumbu Valley, in the area of Sagarmatha National Park, a network of 6 Automatic Weather Stations (AWSs) has been installed over the past 10 years.

Namche Station is part of the station network of automated measurement stations (AWSs) that were installed in the Eastern Himalayas: the AWSs are located at different altitudes, over a stretch oriented approximately 40 km south to north.

The network takes hourly measurements of seven standard parameters: temperature, relative humidity, atmospheric pressure, wind speed and direction, global radiation, total precipitation.

Lineage

WMO (1992) defines air temperature as “the temperature indicated by a thermometer exposed to the air in

a place sheltered from direct solar radiation”. Although this definition cannot be used as the definition of the thermodynamic quantity itself, it is suitable for most applications.

The automatic weather stations (AWS) for monitor meteorological conditions is currently included in the SHARE network. The stations in Nepal and Pakistan are Reference Stations in the CEOP project under the WMO’s World Climate Research Programme (WCRP) – Global Energy and Water cycle Experiment (GEWEX) initiative. Ev-K2-CNR recently founded a special interest group called “CEOP-High Elevation” (CEOP-HE), which is dedicated to understanding multi-scale variability and change in hydrological and energy cycles in high elevation regions and studying their role within the climate system on a local and global scale.

At the Namche AWS the DMA570 Lsi-Lastem Thermohygrometer is mounted on a 2 m pole. It is a probe for measuring air temperature and air relative humidity with replaceable sensitive element for simplify calibration and maintenance. LSI-Lastem supplies a precise and reliable set of probes, suitable for a continuous measurement in severe environments, in presence of deep thermal and hygrometric ranges with high sun radiant heat. An important feature of this set of sensor is that the thermohygrometric sensitive element is easily replaceable, in order to have a simple and rapid ordinary maintenance and avoiding calibration. The Thermohygrometer has supported a considerable improvement, owing to a deep technical and styling development process: a fan ensures a continuos air change around the sensor in order to eliminate temperature fault caused by radiant heat.
