Proxy-based reconstruction of erythemal UV doses over Estonia for 1955–2004 [PDF]
Annales Geophysicae, 2006 A proxy-based reconstruction of the erythemally-weighted UV doses for 1955-2004 has been performed for the Tartu-Tõravere Meteorological Station (58°16' N, 26°28' E, 70 m a.s.l.) site.

Reconciling Observations of Solar Irradiance Variability With Cloud Size Distributions
Journal of Geophysical Research: Atmospheres, Volume 128, Issue 5, 16 March 2023., 2023 Abstract Clouds cast shadows on the surface and locally enhance solar irradiance by absorbing and scattering sunlight, resulting in fast and large solar irradiance fluctuations on the surface. Typical spatiotemporal scales and driving mechanisms of this intra‐day irradiance variability are not well known, hence even 1 day ahead forecasts of variability

Sensitivity distribution along the strips of Compensation pyrheliometers [PDF]
Tellus A: Dynamic Meteorology and Oceanography, 1974 Different sensitivity distribution curves had been found for the sensor of compensation pyrheliometer by laboratory measurement and by calculation. To obtain the real sensitivity distribution a new measuring method was applied, which used the sun as radiation source. The results of laboratory and field measurements were in proper agreement.

Modifying a pyrheliometer to measure direct normal and circumsolar irradiance [PDF]
, 2019 Direct normal irradiance (DNI) is key to concentrating solar power (CSP) systems energy generation. However, pyrheliometric measurements of DNI also include a circumsolar normal irradiance (CSNI) component because the aperture angle of the instrument is ...
