aikatasojen
Aikatasojen is a Finnish term that roughly translates to “time layers” or “time scales.” In academic and applied contexts, it refers to a conceptual framework for analyzing processes that unfold at different temporal resolutions. The idea is to decompose a system into multiple layers, each representing dynamics that operate on a distinct time horizon, so that faster and slower phenomena can be studied without confusing their respective effects.
In practice, aikatasojen involves identifying and modeling several temporal layers, such as micro-time (rapid fluctuations), short-term,
Applications span disciplines, including climate science (separating short-term weather from long-term climate trends), economics and finance
Challenges include ensuring coherent alignment between layers, handling data gaps and nonstationarity, and maintaining interpretability. The
