Advances in ground-based space weather monitoring with compact CALLISTO — •Daniela Banyś1, David Wenzel1, Lutz Heinrich1, Frank Tandler1, and Christian Monstein2 — 1Institute for Solar-Terrestrial Physics, German Aerospace Center (DLR e.V.), Germany — 2Ricerche Solari Locarno IRSOL, Switzerland
DLR has installed various compact CALLISTO receivers as part of the Solar Ionosphere Global Network (SIGN), equipped with spectrometers covering 10-80 MHz, 45-860 MHz, and 1000-1600 MHz in Wairakei, New Zealand. Together with the existing SIGN station in Neustrelitz, Germany, this network provides almost 24/7 continuous observations of solar radio bursts, enabling detailed studies of flare-accelerated electrons and coronal mass ejections. The CALLISTO receivers have been optimized in hardware and software to increase signal-to-noise ratio, simplify maintenance, and improve comparability. Furthermore, a filtering technique has been developed that harmonizes frequency spectra, removes noise, and reduces radio frequency interferences (RFIs), producing cleaner data for automated burst identification and classification.
This setup demonstrates the potential of compact, ground-based CALLISTO stations for continuous solar monitoring and reliable space weather event analysis.
