At the AWS Urdukas station the CM6B Kipp&Zonen pyranometer is installed. It is mounted on a 2m pole. The CM6B 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. A drying cartridge keeps the interior free from humidity. The technical characteristics are: - Spectral range 305...2800 nm (50%points) - Sensitivity 9...15µV/Wm-2 - Impedance 70...100 Ohm - Response time 1/e 5 s, 99 % 55 s - Non-linearity <1.5 % (<1000 W/m2) - Tilt error <1.5 % at 1000 W/m2 - Operating temperature -40...+90 °C - Temperature dependence of sensitivity +/- 2% (-10...+40°C) - Maximum irradiance 2000 W/m2 - Directional error <+/- 20 W/m2 at 1000 W/m2 - Weight 0.85 kg - Cable length 10
