- Purpose
- In the Khumbu Valley, located in the central part of the Himalayan range and including the area of Sagarmatha National Park, a network of 7 Automatic Weather Station (AWSs) has been installed since 1994. These weather stations are located at different altitudes: Lukla (2,660 m a.s.l), Namche (3,570 m a.s.l), Periche (4,260 m a.s.l), Lobuche (5,050 m a.s.l) near the Pyramid Laboratory - Observatory, Kala Patthar (5,600 m a.s.l), Changri Nup Glacier (5,700 m a.s.l) and Mt. Everest - South Col (8.000 m a.s.l). The network mainly takes measurements of 7 standards parameters: air temperature, relative humidity, atmospheric pressure, wind speed and direction, global radiation and total precipitation. Meteo-climatic observations in this area are very important to better understand the environmental changes that are affecting the ecosystem, helping the scientific community to improve the prediction of this environmental phenomena’s evolution and modification. On 2004, the Pyramid AWS has been implemented to include sensors for the determination of soil parameters (temperature, water content, thermal flux), snow level and shortwave/longwave albedo.

- Statement
-
The Pyramid station is equipped with sensors for measuring:
- Standard WMO Meteorological Variables;
-Flux and Soil Parameter.
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.
The Pyramid AWS provides data (with a 60 minute time resolution) of the following parameters:
- station pressure (hPa)
- air temperature (°C)
- relative humidity (%)
- wind speed (m/s)
- wind direction (degree)
- global solar radiation (W/m2)
- total precipitation (mm)
Since 2004 this station has been measuring also the following parameters:
- snow depth (mm)
- incoming shortwave radiation (W/m2)
- outgoing shortwave radiation (W/m2)
- incoming longwave radiation (W/m2)
- outgoing longwave radiation (W/m2)
- soil heat flux (W/m2)
- soil temperature (°C)
- soil moisture (%)
