Lukla Pyranometer

At the Lukla station the the CM6B pyranometer, manufactured by Kipp & Zonen is installed.

This sensor is a first class pyranometer as defined by the World Meteorological Organization. It is

suitable for the measurement of solar irradiance on a plane surface (W/m2).

It incorporates a 64-thermocouple sensor, which is rotationally symmetrical, housed under K5 domes. A white screen prevents the body of the pyranometer from heating up. The pyranometer is supplied with a spirit level and screws for

accurate levelling.
