Seasonal variation of ratios of monthly totals for the components of broadband solar radiation measured in Kishinev, Moldova
Data obtained during 2004–2010 at the ground-based solar radiation monitoring station in Kishinev (Chisinau) are used to study the seasonal variability of the multiyear averaged ratios of a set of monthly totals in four separate spectral sub-bands from UV through near IR relatively to the monthly to...

| Sumario: | Data obtained during 2004–2010 at the ground-based solar radiation monitoring station in Kishinev (Chisinau) are used to study the seasonal variability of the multiyear averaged ratios of a set of monthly totals in four separate spectral sub-bands from UV through near IR relatively to the monthly totals of global radiation both in the UV spectral ranges (280–315 nm and 280–400 nm) and in the main spectral region (280-3000 nm). Spectral sub-bands consist of UV-B, UVe(erythemal), UV-A, Photosynthetically active (400–700 nm), and solar power (400–1100 nm) broadband radiation. Measurements of monthly totals are fulfilled for direct, global and diffuse broadband radiation. In each of cases for these ratios, respective range of values, annual means, minimum and maximum values are defined. It is shown the existence of the seasonal variation for the whole set of ratios. |
