Wide-ranging experience in the meas-urement of solar radiation relies on the development of our own instruments, in which the PMOD/WRC has a long history. Various instruments are of interest . . .

Radiation instruments can be divided into four main categories: Solar, infrared, spectral and ultra-violet radiometers. The calibration of radiometers at PMOD/WRC is performed on our roof-top platform . . .

The PMOD/WRC has conducted research for several decades in the fields of solar physics and solar irradiance monitoring, amongst others. Various datasets are described and made available here . . .

PMOD/WRC, as a designated institute of the Swiss National Metrology Institute METAS and the World Meteorological Organization WMO, participates in the CIPM Mutual Recognition Agreement within. PMOD/WRC . . .
