POEMAS Solar Radio Data – Derived 1s Time Series Dataset (2024-10-01)

The MackSun project provides large-scale solar data collected from scientific instruments, designed for time series analysis, solar activity monitoring, and data-driven research workflows. This dataset contains derived solar radio data from the POEMAS (Polarization Emission of Millimeter Activity at the Sun) instrument, aggregated at 1-second temporal resolution. The data is derived from high-frequency acquisition (10ms) and represents a processed and structured time series suitable for analysis of solar flares, solar radio bursts, and solar activity patterns. The dataset is part of a broader ingestion and processing pipeline capable of handling large volumes of scientific data, supporting high-frequency observations across multiple resolutions (10ms, 100ms, 1s). The pipeline includes validation, normalization, and structured persistence to ensure consistency, traceability, and reproducibility.
