Ground-based radio observations of space weather events with optimized CALLISTO stations

Abstract

Continuous ground-based observations of accelerated electrons are a central element of space weather monitoring and research. Harmful impacts on technological systems are costly and should be reduced in times of rising activity in space. The DLR contributes to this international task by providing reliable radio observations by its own CALLISTO (Compound Astronomical Low frequency Low cost Instrument for Spectroscopy and Transportable Observatory). Various types of radio bursts can be studied across a broad frequency range. The original receivers are optimized in hardware and software to increase the signal-to-noise ratio, ease maintenance work, and provide improved comparability. We present measurements of recent events and capabilities of the instrument.
