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 ...

1st International Pyrheliometer Comparison 1959

Davos, thanks to the excellent world-wide contacts of Walter

Mörikofer to WMO and IRC/IAMAS.

PMOD/WRC today

1228.8.2013

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

International Pyrheliometer Comparison IPC XI 2010

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?
