Radio environment plays an important role in radio astronomy observations. Further analysis is needed on the time and intensity distributions of interference signals for long-term radio environment monitoring. Sample variance is an important estimate of the interference signal decision threshold. He…

Exploiting remote sensing data is a promising approach to estimate surface solar irradiance (SSI). In this study, we propose a method to estimate global SSI using a lookup table and Landsat data. Despite the low temporal resolution of the data used, the developed method produces SSI maps with adequa…
