===Solar irradiance variability===
[[Solar irradiance]] variability assessments are useful for [[solar power]] applications. Solar irradiance variability at any location over time is mainly a consequence of the deterministic variability of the sun's path across the sky dome and the variability in cloudiness. The variability of accessible solar irradiance on Earth's surface has been modeled using Markov chains,<ref>{{cite journal|title=Simple procedure for generating sequences of daily radiation values using a library of Markov transition matrices |last1=Aguiar |first1=R.
