The basic meteorological data are measured by a multi-sensor instrument . The Meteorological parameters measured are: - Air temperature unit[deg C], - Atmospheric pressure[hPa], - Relative humidity[%], - Wind speed[m/s] and direction[deg], - Precipitation[mm].
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.
Continuous surface ozone measurements conducted since 1996 within the Global Atmospheric Watch (GAW) programme of the World Meteorological Organization.

In the Khumbu Valley, in the area of Sagarmatha National Park, a network of 6 Automatic Weather Stations (AWSs) has been installed over the past 10 years. Namche Station is part of the station network of automated measurement stations (AWSs) that were installed in the Eastern Himalayas: the AWSs are located at different altitudes, over a stretch oriented approximately 40 km south to north. The network takes hourly measurements of seven standard parameters: temperature, relative humidity, atmospheric pressure, wind speed and direction, global radiation, total precipitation.

The Condensation Particle Counter (TSI model 3772) detects airborne particles with diameter ranging from 10 nm (counting efficiency > 50%) to 3 µm at an aerosol flow rate of 1.0 l/min, over a concentration range from 0 to 10exp4 particles/cm3.
The basic meteorological data are measured and recorded simultaneously by a Autmatic Weather Station. The Meteorological parameters measured are: - air temperature unit[deg C], - Atmospheric pressure[hPa], - Relative humidity[%], - Wind speed[m/s] and direction[deg], - Precipitation[mm].
