South Col meteorological parameters

On May 15, 2008 the Ev-K2-CNR installed the world’s highest ground automatic weather station (AWS) on Mt. Everest’s South Col at 8,000 m (26,247 ft.) a.s.l. The complex, technologically advanced AWS instrumentation was designed by the Italian manufacturer LSI-Lastem. The sensors were customized to measure temperature, humidity atmospheric pressure, wind speed and direction, global and UVA solar radiation at 8,000 m (26,247 ft.) in extreme environmental conditions lik e very low temperatures and reduced atmospheric pressure.

Quality and validity

Lineage

Continuous measurements:

• air temperature (°C)

• relative humidity (%)

• atmospheric pressure (hPa)

• wind speed (m/s) and direction (°)

• global solar radiation (W/m2)

• UVA radiation

These parameters are recorded every ten minutes and data is transmitted hourly to a server at the Pyramid Laboratory- Observatory (5,050 m asl) and from there to Ev-K2-CNR headquarters in Italy.

The technological innovations:

- High quality weather monitoring instruments were customized and adapted for performance at 8,000 m (26,247 ft.) a.s.l. The sensors and data logger underwent simulation tests in which high altitude conditions were reproduced (environmental temperature of -40°C and atmospheric pressure of 300 hPa) to verify continuous functioning of the electronic components and the data acquisition, storage and transmission mechanisms. The accuracy and stability of the signal measurement by the sensors was further improved after these tests.

- Synchronized radio communications minimize energy consumption and allow for continuous data transmission.

- The weight of the sensor supports was reduced and mechanical components adapted to the presumed installation site conditions, which could only be truly understood once the climbers reached South Col.

- In order to facilitate the work of the climbers in extreme conditions of hypoxia and reduced visibility, the wiring system which connects the sensors to the data logger (“E-log”) was designed so that no tools were needed and connection would be as simple as possible, thus avoiding a complex electrical connection scheme. To avoid possible damage in the case of adverse weather conditions, the unit’s watertight door never needed to be opened during wiring and installation.

- An automatic and remote controlled activation and checking system was designed, so communication and instrumentation tests could be performed in as little time as possible, thus reducing the exposure time of the climbing team.

- The flexible radio repeater system is equipped to handle malfunctions, so data can be transmitted, albeit with a delay, should the radio links break down.
