Comparing ground-level spectrally resolved solar UV measurements using various instruments: A technique resolving effects of wavelength shift and slit width

摘要: Spectrally resolved UV measurements are important for the study of biologically relevant in relation to changes atmospheric parameters. The inter-comparison spectral instruments is essential as measurement techniques and calibrations not standardized. differences slit functions cause large variations when comparing readings directly. method described, which compares using different instruments, corrects wavelength functions, does require knowledge additional parameters UV-transfer model calculations. alignment has an accuracy 0.02 nm over interval from 300–400 nm, a reproducibility 0.01 nm. robustness methods results shown evaluation seven day intercomparison campaign with three scanning spectroradiometers.
