Description

This dataset contains derived solar radio observations from the POEMAS instrument, aggregated at 1-second resolution from high-frequency 10ms acquisition. The aggregation strategy applies median reduction over non-overlapping windows, preserving relevant temporal patterns while reducing noise and stabilizing the resulting time series.

The dataset is suitable for solar flare detection and analysis, radio astronomy studies, time series modeling, signal exploration, machine learning experiments, and data engineering workflows involving real scientific observations.
