Namche (Khumbu Valley, Himalaya - Nepal)

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. In 2004 the station close to the Pyramid and Lukla station have been implemented to include sensors for the determination of soil parameters (temperature, water content, thermal flux), snow level and four components of radiation. 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 Namche Bazar station is located at the Peak Head Quarter and was installed on October 27, 2001. Geographical coordinates: - Latitude: 27° 48' 8.6" N - Lomgitude: 86° 42' 52" E

Ultrasonic Anemometer WMT700

During the 2011 expedition, a prototype replaces the sensor installed during 2008 expedition. A prototype (LSI-Lastem) to support with other two sensors manufactured by VAISALA: WMT700 and WA15D7B. The WMT700 sensor is a robust and reliable ultrasonic anemometer. It measures surface wind, which is one of the key parameters for meteorology and aviation. The WMT700 series uses ultrasound to determine horizontal wind speed and direction.

Sulfur Hexafluoride is measured by using a GC-ECD (Agilent 6890N); separation is performed on a double column system (precolumn/backflush and analytical column, both Hayesep Q), isothemrically. Each run is 15 minute long. Each ambient air sample is bracketed with calibration runs. The working standards are based on NOAA2006 scale.

wind speed

At the AWS Pyramid Laboratory Observatory station the CombiSD DNA022 Lsi-Lastem combined wind speed-direction sensor is mounted on a 5m pole. The CombiSD sensor includes, in a single apparatus, the both transducers for measuring wind speed and wind direction.

wind speed

In the framework of Ev-K2-CNR / SHARE (Stations at High Altitude for Research on the Environment) project the first permanent Automatic Weather Station (AWS) has been installed in Uganda, on July 18, 2006 in the western part of the Stanley Plateau, the biggest Rwenzori glacial mass. The Project was carried out during the celebration of Mt. Ruwenzori first ascent by Duke of Abruzzi in 1906 . This station has the same technical characteristics of the Ev-K2- CNR networks located in the high altitude regions of Himalaya and Karakorum. The station records continuously measurements of the seven meteorological standard parameters: air temperature, relative humidity, wind speed and direction, atmospheric pressure, global solar radiation and total precipitation. The Rwenzori observations will permit to study physical and dynamical processes at Africa high elevations in the framework of SHARE and GEWEX-CEOP HE programs to improve our understanding of variability and change in hydrological and energy cycles and their role in the climate system.

Air temperature

At Changri Nup station a DMA 570 thermohygrometer was installed in 2010. Temperature sensitive element is a thermoresistance Pt100 type while the humidity sensitive element is a capacitive plate. The sensitive elements are protected from incident solar radiation by a double radiation shield. Sensors for temperature and relative humidity measurements with radiation shield for meteorological uses. Sensors are equipped with a microprocessor.

atmospheric pressure

The station records continuously measurements of the seven meteorological standard parameters: air temperature, relative humidity, wind speed and direction, atmospheric pressure, global solar radiation and total precipitation. A barometer CX115P LSI-Lastem (Italy), measures atmospheric pressure (hPa).
