Low-frequency solar radio bursts and their space weather implications

The Sun is a radio emitter in the millimeter to kilometer wavelength range (100s of GHz to a few kHz). The low frequency solar radio bursts are of particular importance, because they are associated with large-scale solar eruptions and the associated interplanetary disturbances such as coronal mass ejections (CMEs) and shocks. The radio bursts are produced by energetic electrons (>1 keV) by nonthermal processes. The radio bursts provide important information not only on the solar disturbances but also on the ambient medium.
