    Monitoring the Dynamics of the Ionosphere–Plasmasphere System by Ground-Based ULF Wave Observations (2009)
    In:  Earth Moon and Planets
    Details
    Publikationsdatum: 2020-02-12
    Beschreibung: Cross-spectral analysis of ULF wave measurements recorded at ground magnetometer stations closely spaced in latitude allows accurate determinations of magnetospheric field line resonance (FLR) frequencies. This is a useful tool for remote sensing temporal and spatial variations of the magnetospheric plasma mass density. The spatial configuration of the South European GeoMagnetic Array (SEGMA, 1.56 L1.89) offers the possibility to perform such studies at low latitudes allowing to monitor the dynamical coupling between the ionosphere and the inner plasmasphere. As an example of this capability we present the results of a cross-correlation analysis between FLR frequencies and solar EUV irradiance (as monitored by the 10.7-cm solar radio flux F10.7) suggesting that changes in the inner plasmasphere density follow the short-term (27-day) variations of the solar irradiance with a time delay of 1–2 days. As an additional example we present the results of a comparative analysis of FLR measurements, ionospheric vertical soundings and vertical TEC measurements during the development of a geomagnetic storm.

    The electronic Space Weather upper atmosphere (eSWua) project at INGV: advancements and state of the art (2007)
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: The eSWua project is based on measurements performed by all the instruments installed by the upper atmosphere physics group of the Istituto Nazionale di Geofisica e Vulcanologia, Italy and on all the related studies. The aim is the realization of a hardware-software system to standardize historical and real-time observations for different instruments. An interactive Web site, supported by a well organized database, can be a powerful tool for the scientific and technological community in the field of telecommunications and space weather. The most common and useful database type for our purposes is the relational one, in which data are organized in tables for petabytes data archiving and the complete flexibility in data retrieving. The project started in June 2005 and will last till August 2007. In the first phase the major effort has been focused on the design of hardware and database architecture. The first two databases related to the DPS4 digisonde and GISTM measurements are complete concerning populating, tests and output procedures. Details on the structure and Web tools concerning these two databases are presented, as well as the general description of the project and technical features.

    A new campaign for oblique-incidence ionospheric sounding over Europe and its data application (2008)
    Elsevier
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: New systematic oblique ionospheric radio sounding measurements over Central Europe, concerning the radio links between Inskip (UK, 53.51N, 2.51W) and Rome (Italy, 41.81N, 12.51E) and between Inskip and Chania (Greece, 35.71N, 24.01E), have been performed since November 2003. Different long-term (i.e. monthly median) ionospheric predictions and nowcasting techniques have been applied and compared with the oblique-incidence radio sounding measurements. The MUF (basic maximum usable frequency) measurements observed during the early part of the experiment have been used to compare the performances of different methods. The preliminary analysis has shown good performances for the long-term prediction models, in particular in winter months for ICEPAC (ionospheric communications enhanced profile analysis and circuit) and in equinox/summer months for ASAPS (advanced stand-alone prediction system) and SIRM&LKW (simplified ionospheric regional model & lockwood). The nowcasting methods SIRMUP&LKW (SIRM updating method & lockwood) and ISWIRM (instantaneous space weighted ionospheric regional model) reveal good results for moderate and disturbed geomagnetic conditions when compared with the long-term prediction methods.

    The new ionospheric station of San Miguel de Tucumán (2007)
    INAG - Ionosonde Network Advisory Group
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: At the end of August 2007 an Advanced Ionospheric Sounder (AIS), built at the Istituto Nazionale di Geofisica e Vulcanologia (INGV), Rome, Italy, was installed at San Miguel de Tucumán, Argentina (geographical coordinates: 26.9 S, 294.6 E; magnetic coordinates: 15.5 S, 3.8 E), particularly interesting for its location, near the southern peak of the equatorial anomaly. AIS-INGV is a digital low-power pulse-compressed ionosonde. In order to reduce the transmitted power, weight, size, power consumption, and to have an excellent reliability, advanced HF-radar techniques were employed. The ionosonde is also equipped with Autoscala, a software able to perform an automatic scaling of the ionogram.

    L'osservatorio ionosferico in Artide e Antartide: osservazioni sperimentali e risultati scientifici (2011)
    Associazione Geofisica Italiana
    Details
    Publikationsdatum: 2017-04-04
    Beschreibung: The Italian Upper Atmosphere Observatory at polar latitude was firstly established during the Antarctic campaign 1990-1991 to support the telecommunication logistic activity of the National Program for Antarctic Research (PNRA). The Istituto Nazionale di Geofisica e Vulcanologia (INGV), formerly Istituto Nazionale di Geofisica (ING), was involved in this action as the long time experience in HF radar, ionospheric sounding and ionospheric prediction services for radio communication purposes, managing two of the most important and historical ionospheric observatories all over the world: Rome (41.8N, 12.5E) and Gibilmanna (37.9 N, 14.0 E). Since that time, starting from 1993 up to now, several research projects have been carried on focusing on the multi instruments upper atmosphere observations in Arctic and Antarctica with the aim to study the polar ionosphere in different time and space domains, contributing both to the Global Change and to the emerging Space Weather needs. Here we briefly report on the experimental activities as well on the main scientific results obtained highlighting the latest findings in the field of bipolar GNSS (Global Navigation Satellite Systems) ionospheric scintillation measurements and investigation.
