In Italy, the first observatory was founded in 1880, when Pietro Tacchini, the director of the Central Meteorological Institute (Ufficio Centrale di Meteorologia), launched an initiative to study the distribution of the Earth's magnetic field over the Italian territory. http://hdl.handle.net/2122/3832 Title: PEGASO: An ultra light long duration stratospheric payload for polar regions flights <br/> <br/>Authors: Iarocci, A.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma1, Roma, Italia; Benedetti, P.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma1, Roma, Italia; Caprara, F.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione CNT, Roma, Italia; Cardillo, A.; CNR, Italy; Di Felice, F.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma1, Roma, Italia; Di Stefano, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma1, Roma, Italia; Drakøy, P.; ARR, Norway; Ibba, R.; ASI, Italy; Mari, M.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma1, Roma, Italia; Masi, S.; La Sapienza Unuversity, Rome, Italy; Musso, I.; CNR, Italy; Palangio, P.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma2, Roma, Italia; Peterzen, S.; istar, USA; Romeo, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma1, Roma, Italia; Spinelli, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma1, Roma, Italia; Spoto, D.; ASI, Italy; Urbini, G.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma1, Roma, Italia <br/> <br/>Abstract: Stratospheric balloons are powerful and affordable tools for a wide spectrum of scientific investigations that are carried out at the stratosphere level. They are less expensive compared to satellite projects and have the capability to lift payloads from a few kilograms to a couple of tons or more, well above the troposphere, for more than a month. Another interesting feature of these balloons, which is not viable in satellites, is the short turnaround time, which enables frequent flights. We introduce the PEGASO (Polar Explorer for Geomagnetism And other Scientific Observations) project, a stratospheric payload designed and developed by the INGV (Istituto Nazionale di Geofisica e Vulcanologia), Rome and La Sapienza University, Rome. The project was sponsored by the PNRA (Progetto Nazionale di Ricerche in Antartide), Italy (Peterzen et al., 2003). This light payload (10 kg) was used by the Italian Space Agency (ASI) and Andoya Rocket Range (ARR) for five different scientific missions. PEGASO carries a 3-component flux-gate magnetometer, uses a solar cell array as the power source and has a GPS location system. The bi-directional telemetry system for data transfer and the remote control system were IRIDIUM based http://hdl.handle.net/2122/3669 Title: MIRTO: a prototype for real-time ionospheric imaging over the Mediterranean area <br/> <br/>Authors: Alfonsi, Lu.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma2, Roma, Italia; Mitchell, C. N.; Department of Electronic and Electrical Engineering, University of Bath, U. K.; Romano, V.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma2, Roma, Italia; Spalla, P.; Istituto di Fisica Applicata "Nello Carrara" (IFAC), CNR, Sesto Fiorentino (FI), Italy <br/> <br/>Abstract: MIRTO (Mediterranean Ionosphere with Real-time TOmography) is a collaborative project between Istituto Nazionale di Geofisica (INGV) of Rome, the University of Bath (U.K.) and the Istituto Fisica Applicata «Nello Carrara»-Consiglio Nazionale delle Ricerche (IFAC-CNR) of Florence. The goal of the project is the development of a prototype for real-time imaging of the ionosphere over the Italian region with extension to the Mediterranean Sea. MIRTO uses an original imaging technique developed at the University of Bath and upgraded for real-time use in cooperation with IFAC. The prototype makes use of the data acquired by the real-time ionospheric and geodetic instrumentation operated by INGV. Such measurements drive the imaging algorithm to produce the image of electron density as well as maps and movies of the Total Electron Content (TEC) over the considered area. http://hdl.handle.net/2122/3515 Title: Rapid neuronet inversion of 2D magnetotelluric data for monitoring of geoelectrical section parameters <br/> <br/>Authors: Shimelevich, M. I.; Moscow State Geoprospecting University, Moscow, Russia; Obornev, M. A.; Moscow State Geoprospecting University, Moscow, Russia; Gavryushov, S.; Engelhardt Institute of Molecular Biology, Moscow, Russia <br/> <br/>Abstract: The inverse MagnetoTelluric (MT) operator is approximated by means of the Neural Network (NN). The methodology of the NN interpretation in classes of the geoelectrical sections described by the hundreds of parameters is proposed. Error of the NN inversion and field misfit are evaluated. A rapid NN algorithm solving the inverse problem and detecting changes of time-dependent dynamic parameters of the section is applied to 2D synthetic data.
