SVIRCO (Studio delle Variazioni d'Intensita' dei Raggi COsmici) Observatory The SVIRCO Observatory performs continuous measurements (since July 1957) of the secondary nucleonic component of the galactic cosmic ray intensity, through a neutron monitor (NM-64 type). The SVIRCO Observatory is the only facility of its kind existing in Italy, it represents a national asset of inestimable value and it is characterized by efficiency and reliability. The SVIRCO Observatory is part of the worldwide network of neutron monitors and it is considered to be one of the essential observational sites for research in the fields of cosmic ray physics, solar-terrestrial relations and Space Weather. Monica Laurenza monica.laurenza@inaf.it The SVIRCO Observatory is located at the Department of Mathematics and Physics of the University Roma Tre. Energy Range: nucleonic component produced by primary cosmic rays at rigidities >6.3 GV * 1 min, 5 min, hourly, daily and monthly averaged data and plots of pressure corrected nucleonic intensity and of barometric pressure data Archive at the SVIRCO Observatory (acquisition disk and several back up); * Agreement between INAF-IAPS and University of Roma Tre for the SVIRCO Observatory maintenance
Routine and Max Sampling Rate(s): 1 min and 5 min * 5 min and hourly overall multiplicity data, sorted into separated counting channels (from 1 to greater than 8) SVIRCO (http://webusers.fis.uniroma3.it) and NMDB (www.nmdb.eu) websites * The SVIRCO Observatory is part of the worldwide network of standardized neutron monitors
Field of View: equatorial asymptotic directions * Daily amplitudes and phases of the first three harmonics of the diurnal wave Real time data are sent to NMDB, to the ESA – SSA SWE Space Radiation Expert Service Centre for the Real Time GLE ALERT System to forecast GLEs and the AVIDOS application for real time radiation dose estimation * Partner of the “Real-time database for high-resolution neutron monitor measurements” for Space Weather applications, funded in 2008–09 by the European Union’s 7th Framework Programme as an e-Infrastructures project in the Capacities section
