TSRS 2.0 AND SOLAR RADIO DATA FOR GNSS SPACE WEATHER APPLICATIONS

Solar radio emission, a key indicator of solar activity, is crucial for monitoring and predicting Space Weather, particularly for its impact on technological infrastructures, such as global navigation satellite systems (GNSS). The Trieste Solar Radio System 2.0 (TSRS 2.0) is a new radio spectropolarimeter dedicated to operational Space Weather monitoring and forecasting, installed in Basovizza (Trieste, Italy) that will provide both solar radio indices and synoptic images of the solar disk. While awaiting the availability of data from the newly-installed TSRS 2.0, other solar radio data sources have been utilized for time series analysis and development of dedicated algorithms for time series prediction, such as F10.7 index. Additionally, K-band radio images from the INAF SunDish project can probe the chromospheric magnetic field of the Active Regions (AR) through the detection of gyro-resonance spectral components related to flare events. Through correlation statistics analysis between sporadic anomalous AR spectrum and strong flares we discuss the relevant outcomes and the effectiveness of the developed methodologies. In the framework of INAF National Solar Radio Network, the upcoming Solaris Project of smart Solar monitoring system at high radio frequencies, based on single-dish imaging techniques, will be the only Solar facility offering continuous monitoring at 100 GHz, nearly 20h/day in Antartica with optimal sky opacity.
