Proceedings from the WMO Technical Conference on Meteorological and Environmental Instruments and Methods of Observation
(TECO-2022) are now publicly available here. Markus Suter (Davos Instruments) and Wolfgang Finsterle (PMOD/WRC) have contributed their work: Adaptive diffraction corrections in solar radiometry, a prerequisite for the ISO 9060:2018 AA class.

Adaptive Diffraction Corrections
The Diffraction Effect and its implications
Diffraction effects in solar radiometry become more and more important once the target uncertainty goes below 0.1%. At the radiometric two aperture system, diffraction occurs at the front aperture, and thus reduces or enhances the amount of solar radiation passing the second aperture and reaching the detector. This strongly wavelength dependent effect has an impact in the order of 0.1% and can increase by up to 50% depending on the spectral conditions. This leads to an error in the measurement that needs to be corrected if high accuracy is needed.

Diffraction effects in solar radiometry are nothing new, they have been discussed at several occasions, mostly in conjunction with establishing absolute scales. When it comes to extremely precise measurements, as the ISO 9060 AA-class calls for, it is worth to look at diffraction a little closer.

Meet us at the Meteorological Technology World Expo in Geneva (June 5.-7.) Play with our control unit Linard and have a look at our prototype of the PMO8 generation that is designed to meet the ISO 9060:2018 AA-class specifications. We are looking forward to seeing you at stand: 8070.
Happy New Year
Davos Instruments is looking forward to a new inspiring year. We are currently working on the first AA-class radiometer according to ISO 9060:2018. Stay tuned!
