Senior researcher at PMOD World Radiation Center, Switzerland (PMODWRC)
The Physikalisch-Meteorologisches Observatorium Davos/World Radiation Center (PMOD/WRC):
Serves as an international calibration center for meteorological radiation instruments.
Develops radiation instruments for use on the ground and in space.
Researches the influence of solar radiation on Earth’s climate.
Since its establishment in 1907, the Physikalisch-Meteorologisches Observatorium Davos (PMOD) has been studying the influence of solar radiation on the Earth’s climate. In 1926, the Observatory joined the Swiss Research Institute for High Altitude Climate and Medicine Davos and has since become part of this foundation. At the request of the World Meteorological Organization (WMO), the Federal Council decided in 1970 to finance a calibration center for radiation measurement as Switzerland’s contribution to the World Weather Monitoring Program of the WMO. Following this decision, the PMOD was commissioned to establish and operate the World Radiation Center (WRC).
The World Radiation Center maintains the primary standard for solar irradiance consisting of a group of high-precision absolute radiometers. In response to further inquiries from the WMO, a calibration center for atmospheric longwave radiation measuring instruments was established in 2004, and in 2008 the calibration center for spectral radiance measurements to determine atmospheric turbidity. Since 2013, the European UV calibration center has also been operated by the World Radiation Center. The World Radiation Center today consists of four sections:
Solar Radiometry (WRC-SRS)
Infrared Radiometry (WRC-IRS)
Atmospheric Turbidity (WRC-WORCC)
UV Radiometry (WRC-WCC-UV)
The calibration activity is embedded in an internationally recognised quality system (ISO 17025) to ensure reliable and traceable compliance with the quality standard.
