Traceability for surface spectral solar ultraviolet radiation

Annotation in Czech

The Joint Research Project "Traceability for surface spectral solar ultraviolet radiation" will significantly enhance the reliability of spectral solar UV radiation in the wavelength range 300 nm to 400 nm measured at the earth surface by developing newmethods of observation (techniques and devices) to provide traceable solar UV irradiance measurements with an uncertainty of less than 2 %. This activity is essential to unambiguously quantify decadal changes in solar UV radiation due to the expected changes in the global climate system. The project will shorten the traceability chain of the solar UV measurements to the SI unit and to reduce the associated transfer uncertainties. The goal is to approach uncertainties in the field comparable to those currently achieved only for primary spectral irradiance scale realisations at NMI level, i.e., at the level of 1 %. To provide traceable solar UV irradiance measurements with an uncertainty of less than 2 %, the portable reference spectroradiometer known as´QASUME´ will be fitted with an improved global entrance optic and newly developed solid-state detectors. To support the use of cost-effective array spectroradiometers in UV monitoring networks (as replacements for current UV filter Radiometers), significant progress needs to be achieved in the characterisation of these devices. New characterisation techniques and post-correction methods will be developed to determine and correct the stray light, linearity, and wavelength scale of array spectroradiometers. The dissemination of the improved irradiance traceability and the developed tools and methods for using array spectroradiometers in the solar UV range will occur by a large field intercomparison of spectroradiometers organised at the end of the JRPat the World Radiation Centre, in Davos, Switzerland.
