OVRO LWA Solar Observation

astronomy hdf5 machine learning solar space weather weather

Description

This dataset contains long-term low-frequency solar radio imaging spectroscopy observations from the Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA). The data are produced from solar radio interferometric observations and distributed as HDF5 spectral image products and FITS all-day spectrogram products, with metadata describing the observation time, frequency coverage, imaging products, and other relevant parameters. The dataset provides dynamic, imaging-based measurements of solar radio emission at low frequencies, which are closely connected to solar coronal activity, solar radio bursts, and space weather phenomena. These observations support studies of solar eruptions, particle acceleration, coronal plasma properties, radio wave propagation, and machine learning applications for solar radio burst detection, event classification, anomaly detection, and space weather prediction.

Update Frequency

New observations are added regularly. The dataset currently contains approximately 12 TB and grows by approximately 9 TB per year.
