Synthetic Spectra is an estimation of the continuous spectrum of UV spectral irradiance incident at the surface. It is derived using an algorithm that can be best described as a physically consistent curve fitting algorithm, in which the UV-MFRSR measurements are used to determine a continuous transmittance curve for UV radiation. The transmittance is multiplied by the extra-terrestrial radiation to produce total, diffuse and direct spectral irradiances. For further information see Min and Harrison(1998).
Graphs of the data are available for a time selection of a day. The time period for the graphs will be every 15 minutes between 10:00 am and 3:00 pm local time. The graphs will be displayed along with a tabular view of all data used to create the graph. The tabular view will contain the values for every 3 minutes, instead of the 15 minutes. We also provide a feature to export the data to a file on your local computer in a comma delimited(CSV) format.If your selection is for over a day, a comma separated file will be generated for you to download to your local computer.
