The laboratory was installed and became operational in September 1990. Not only did the Pyramid soon become a fundamental
scientific outpost for researchers and technicians, but it also grew to be known as a point of reference for local populations
and tourists who could take advantage of the advanced telecommunications systems available there to send urgent messages to
Kathmandu or abroad.
The Pyramid International Laboratory - Observatory was officially inaugurated in October or 1990, by the Prime Minister of
Nepal, a RONAST officer, the Italian Ambassador in Kathmandu, Agostino Da Polenza and the incredible Ardito Desio, who, at
the age of 93, would not miss the historic occasion, making the trip personally to the Pyramid's 5,050 meters a.s.l.
The facility is operated by the Ev-K2-CNR and the Nepal Academy of Science and Technology. Their partnership has given rise
to 520 scientific missions with the participation of 220 researchers and 143 different international scientific institutions.
The independent lodge is made in the style of Nepalese lodge architecture and can host up to 20 researchers, technicians
and logistics staff.
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.
