  7. Past – Present – FutureDirector PMOD/WRC Werner SchmutzAugust 28., 2013

  8. PMOD 1907 Carl Dorno founded the PMOD in 1907 Carl Dorno 1865-1942 The PMOD was located in the „Villa Dora“ until 1976

  9. Dorno rays The focus of research at the Physikalisch-Meteorologisches Observatorium Davos (PMOD) was the measurement of radiation. In particular: UV radiation, which was later named “Dorno Strahlung” (“Dorno rays” is still used in medicine) The measurement platform was on the roof of „Villa Dora“ Most instruments are preserved in the PMOD/WRC archive

  10. The long path to the creation of the World Radiation Center 1934 workshop at PMOD dedicated to compare pyrheliometers 1956 the Radiation Commission of IAM and the CIMO/WMO Working Group on Radiation held a joint meeting in Davos The main theme of the 1956 meeting was the definition of the Standard Scale of Radiation Conclusion:  Need of regular International Pyrheliometer Comparisons ...

  11. 1st International Pyrheliometer Comparison 1959 1970 creation of theWorld Radiation Center in Davos, thanks to the excellent world-wide contacts of Walter Mörikofer to WMO and IRC/IAMAS. Walter Mörikofer director of PMOD 1934 workshop at PMOD dedicated to compare pyrheliometers 1956 the Radiation Commission of IAM and the CIMO/WMO Working Group on Radiation held a joint meeting in Davos The main theme of the 1956 meeting was the definition of the Standard Scale of Radiation Conclusion:  Need of regular International Pyrheliometer Comparisons ... IPC I 1959 – On theroof of the PMOD, house Dora, Davos Platz

  12. PMOD/WRC today PMOD/WRC is a branch of the foundation SFI World Radiation Center since 1971 Operational serviceResearch Energy balance and influence of radiation on the terrestrial climate • Green house effect • Sun-Earth connection Calibration of meteorological instruments measuring radiation Development of instruments and methods

  13. International Pyrheliometer Comparison IPC XI 2010 The PMOD/WRC is still responsible for theWorld Radiometric Reference (WRR) and the organization of the IPCs every 5 years. WRR

  14. Space experiments are built in house at PMOD/WRC In particular for the measurement of the Total Solar Irradiance, e.g.: • 1995 VIRGO/SOHO (PI Claus Fröhlich) • 2010 PREMOS/PICARD(PI Werner Schmutz) • 2015 CLARA/NORSAT-1

  15. Total Solar Irradiance measurements in space since 1979 PREMOS is the first fully SI traceable calibrated radiometer in space PREMOS/PICARD is the first fully SI traceable calibrated radiometer in space (SI = International System of Units) PICARD launched 2010

  16. PREMOS on PICARD PREMOS is the first fully SI traceable calibrated radiometer in space PREMOS established the absolute value of the Total Solar Irradiance On 27. July 2010 the Total Solar Irradiance was 1360.9 W/m² ±0.4 W/m2

  17. Why radiation research ? What is the anthropogenic contribution during the last 100 years? How much is natural warming? O.5 oC in the last 30 years are antropgenic

  18. The terrestrial temperatureis forced Estimated TSI in the past byShapiro et al., 2011

  19. “Little ice age” 17th century

  20. TSI monitoring needs to continue … What if the Sun has a “Maunder Minimum like” minimum in the future? Solar minimum called “Maunder Minimum” ongoing scientific discussion …and continued need of PMOD/WRC activities ! Hypothetical decrease of TSI

  21. Acknowledgments The PMOD/WRC has a radiant future thanks to the support of: WMO MeteoSwiss Kanton Graubünden Gemeinde Davos The renovation is a success story thanks to: BundesamtfürBauten und Logistik Emch+Berger Gesamtplanung Architektschumacher Elektrizitätswerk Davos AG
