The "Physikalisch-Meteorologisches Observatorium Davos" (PMOD) was founded in 1907 by Carl Dorno as a privately operated institute with the objective of finding out why tuberculosis patients were curing better in Davos than elsewhere.
It's current research activites include:
- Development of instruments and calibration procedures for absolute total and spectral solar and long-wave radiometry;
- Investigation of the solar total irradiance, its spectral distribution and variability for global climate research, solar physics and helioseismology (VIRGO Experiment);
- Investigation of radiation in the atmosphere and at the ground to determine its spectral distribution and variability in the UV, for diagnostics of the atmospheric composition and aerosol content as well as to determine the surface radiation budget within the ASRB program.
