PMOD 1907
• 828.8.2013
Carl Dorno founded
the PMOD in 1907
The PMOD was located in the „Villa Dora“ until 1976
Carl Dorno 1865-1942
Dorno rays
• 928.8.2013
• 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
The long path to the creation of the World Radiation Center
• 1028.8.2013
• 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 ...

Walter Mörikofer director of PMOD
1970 creation of the World Radiation Center in
Davos, thanks to the excellent world-wide contacts of Walter
Mörikofer to WMO and IRC/IAMAS.
PMOD/WRC today

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

The PMOD/WRC is still responsible for the World Radiometric Reference (WRR) and the organization of the IPCs every 5 years.

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

Total Solar Irradiance measurements in space since 1979
28.8.2013
• 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

PREMOS on PICARD
28.8.2013
• 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

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