Self-study manual on optical radiation measurements. Part 3. Applications, chapter 1. Measurement of solar terrestrial spectral irradiance in the ozone cut-off region
Abstract
This is the first chapter in Part 2 (Applications) of this Manual. Material developed in earlier chapters is used to perform state-of-the-art measurements in Gainesville, Florida, of solar terrestrial spectral irradiance between 290 (nm) and 340 (nm). The measurement equation is used to design the experiment and to address the effects of polarization, non-linearity, spectral scattering, distortion, slit-scattering function, spectral irradiance calibration, and wavelength calibration. Estimates are made of the uncertainties associated with all these factors. The total uncertainty is estimated to be about 10 percent. An appendix includes details for computing the solar terrestrial spectral irradiance between 280 and 310 (nm). Suggestions are made for reducing the uncertainty by about one third and for further research in UV solar terrestrial measurements.
