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 Lukla station was installed on September 2002. On 2004, the AWS has been implemented to include sensors for the determination
of soil parameters (temperature, water content, thermal flux), snow level and shortwave/longwave albedo.
