For the 8th consecutive year, the JRC Directorate C “ESTI” is organizing the International SpectroRadiometer Comparison (ISRC). It is hosted on the premises of INTA in Madrid (Spain). This year ISRC will take place from the 4th to the 8th of June 2018.
The main goal of ISRC is the harmonization of good practices in measurement and instruments traceable calibration procedures for solar spectra and irradiance measurements within the PV community. Recently also for atmospheric physics and metrological institutions, especially in relation to the need for traceable spectral irradiance measurements. Not only spectro-radiometers of the various participants will be compared to the JRC reference, but also thermopile instruments (pyrheliometers and pyranometers) will be verified against the JRC Directorate C “ESTI’s” references (Absolute cavity radiometers directly traceable to WRR- PMOD, Switzerland).
At last year’s edition, 15 institutions with 22 researchers participated from all over Europe.
