1 MMMM T S R S Summary of TSRS Objectives The Trieste Solar Radio System (TSRS; INAF-Trieste Astron. Obs.), is a set of two multichannel solar radio polarimeters with the following features:The Trieste Solar Radio System (TSRS; INAF-Trieste Astron. Obs.), is a set of two multichannel solar radio polarimeters with the following features: –6 channels (237, 327, 408, 610, 1420, 2695 MHz) –Measure of radio flux density and circular polarization –High time resolution (1 msec) –Real-time observing mode –Near-real-time publication of data, radio indices and nowcasting One of the 7 systems in the world with radio polarimetryOne of the 7 systems in the world with radio polarimetry Unique in EU and in the world with the above featuresUnique in EU and in the world with the above features The sole dedicated solar radio system operated in ItalyThe sole dedicated solar radio system operated in Italy Aimed at the surveillance of coronal radio emission levelsAimed at the surveillance of coronal radio emission levels

2 MMMM T S R S Summary of TSRS User Needs The primary goal of TSRS has been the study of solar radio phenomena and the radiophysics. In 2000 it was upgraded to operate in near-real-time for Space Weather and in 2003 it joined SWENET.The primary goal of TSRS has been the study of solar radio phenomena and the radiophysics.

No detailed analysis exists yet on potential users such as:No detailed analysis exists yet on potential users such as: a.Ionosphere forecasters (2695 MHz 11 cm R & EUV proxy) b.Radio communication providers c.Mobile communication providers d.Military communication organizations The minimization of possible interferences from solar radio noise by the users needs:The minimization of possible interferences from solar radio noise by the users needs: –Accessibility to multi-band, real-time monitoring of solar radio emission via solar radio indices and peak radio level values. –Availability of 1-min-ahead nowcasted values for solar radio noise. –Prompt issueing of alerts and warnings by various means.

3 MMMM T S R S Evaluation of User Satisfaction and Financial Benefit As no direct contact with potential users has been performed yet, no specific answers can be given about the user satisfaction.As no direct contact with potential users has been performed yet, no specific answers can be given about the user satisfaction. The financial benefit that can be guessed for the users will strictly depend on:The financial benefit that can be guessed for the users will strictly depend on: –Their level of awareness about the improvement in prediction reliability when using the 11 cm index with 1 min time cadence. (Users a., d.) –Their level of awareness about the interferences by solar radio noise the communications systems they operate can suffer. (Users b., c., d.) –Their willingness to accept and admit such potential weakness in their technological systems. (Users b., c., d.) The above item is much more relevant to providers and organizations, which operate mission-critical communication systems.The above item is much more relevant to providers and organizations, which operate mission-critical communication systems.

4 MMMM T S R S Sustainability of TSRS Service TSRS has been operating at increasing levels of technical and operational improvements since 1967.TSRS has been operating at increasing levels of technical and operational improvements since At the present time, TSRS is under review by the National Institute for Astrophysics (INAF), whose outcome may result in either resolutions:At the present time, TSRS is under review by the National Institute for Astrophysics (INAF), whose outcome may result in either resolutions: a)TSRS will be declared an observing resource of national interest it will be minimally funded and will continue operating but with no foreseeable developments. b)TSRS will be declared a minor observing resource of no national interest it will not be funded and will stop operating, if no external sources of funds will be found. Non-Recurrent Cost Digital Acquisition System Upgrade Manpower 30 kEuro Consumables 10 kEuro TOTAL 40 kEuro Annual Cost TSRS Operation & Maintenance Investment 5 kEuro Consumables Operation TOTAL 15 kEuro

5 MMMM T S R S Prospective for Improvement of TSRS Service A new ultra-fast digital acquisition system can provide:A new ultra-fast digital acquisition system can provide: –Improved sampling frequency (2 to 5 kHz; msec). –Publication of radio indices with a time cadence of 1 minute (presently: 10 minutes, due to hardware limitations). The design was already carried out and the hardware and software development systems were already acquired.The design was already carried out and the hardware and software development systems were already acquired. The lack of funds and of manpower forced to temporarily stop such an upgrade, which has great potentialities for both radio science as well as for Space Weather applications.The lack of funds and of manpower forced to temporarily stop such an upgrade, which has great potentialities for both radio science as well as for Space Weather applications.
