SHARE (Stations at High Altitude for Research on the Environment) Network

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 Stations (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.
The Kala Patthar AWS was installed on May 2008, at 5600 m asl.

Geographical coordinated:
- Latitude: 27deg 59' 24" N
- Longitude: 86deg 49' 48" EKala Patthar AWS provides data (with a 10 minute time resolution) of the following parameters:
- air temperature (degC)
- relative humidity (%)
- atmospheric pressure (hPa)
- global solar radiation (W/m2)
- UVA radiation (W/m2)
- wind speed (m/s)
- wind direction (degree)
- total precipitation (mm)
