Ionospheric Physics
The terrestrial upper atmosphere includes a region rich of free electrons and ions, known as ionosphere, which extends from 50 km of altitude upwards. The high concentration of free electrons makes the ionosphere an electromagnetic medium, sensitive to the passage of electromagnetic waves and to the presence of charged particles coming from the outer space. The electron concentration depends on the height above sea level, being larger at around 300-400 km, in the so-called “F region”. Below the F region, the “E” and “D” regions present a weaker ionization, but show a high sensitivity to the charged particles injection occurring when an ionospheric storm onsets.

Since its establishment in 1936 the Istituto Nazionale di Geofisica (the Italian national institute for geophysics) has been engaging in ionospheric physics studies. Over the years, the Institute has evolved expanding its fields of study within the Earth physics, becoming Istituto Nazionale di Geofisica e Vulcanologia (INGV), nevertheless ionospheric physics has been continuing in playing a fundamental role among the Institute goals. Exploiting this long-standing experience today we are able to carry out feasibility studies of long range links in the HF band. To this aim, recently the project  SWING investigated the feasibility of data links based upon ionospheric propagation, to be activated quickly in case of crisis in the normal working of the infrastructures assigned.

Remote sensing and Geodesy for Geohazard monitoring

As a spin-off of INGV we inherit a long standing experience in the use of optical and radar remote sensing and geodetic methods for the monitoring and analysis of geological and geophysical hazards: volcanic eruptions, earthquake faults, land subsidence, deep seated landslides and gravitational deformations, sinkholes, etc.
We use a multiple-scale approach, exploiting a wide range of satellite, airborne (manned and unmanned), and ground-collected data, and apply standard and non-standard measuring and modeling techniques to generate high-resolution, high accuracy maps of different geophysical and environmental parameters. We can provide advanced scientific products, as well as consultancy services, in these subjects.

HF and VHF radar

During the last two decades the INGV technologists and researchers have been developing skills in designing and engineering of remote sensing instruments, working in the HF and VHF bands. In the HF’s the AIS ionosonde has been built. It is employed for ionospheric monitoring to the aim of calculating the electron density profile and forecasting usable frequencies for radio links. In the VHF’s radars have been developed which sound glacial layering; they can be ground based or airborne. Our expertise concern the design and development of the RF hardware, the acquisition circuitry, the software for the instrument control, and the antennas construction.

Space Weather

Dynamic and constant solar effects on Earth. The two solar constants, sunlight and solar wind, takes 8 minutes and 4 days, respectively, to reach Earth. Arrival times of dynamic solar events such as flares, solar energetic particles and CMEs, are approximated and range from immediate effect to several days. Credit: NASA/Berkley.

Earth is not only enlightened by the Sun. Our planet is also continuously swept by a flux of particles emitted from the star with embedded “frozen” magnetic fields which confines the Earth’s magnetosphere in a drop shaped envelope in the radial direction from the Sun to the Earth. [read more]

 

Environmental Geophysics

SpaceEarth Technology offers its expertise and the latest technology in the field of geophysical exploration to obtain as quickly and efficiently the information you need to know and see the structure of the subsoil, the first meters of depth up to several hundred meters. This information is derived through the different techniques of geophysical exploration, which are non-invasive methods, exploiting the contrasts in the physical properties of the subsurface is due to natural reasons (geological stratification, presence of ground water, sea water intrusion, etc.) that by man (underground structures, landfills, underground utilities, etc.).

mm7Marine monitoring
We have been getting scientific data from the sea for more than ten years. In these years we collaborated on experiments to monitor seismicity, marine mammals passages, deep current changes, chemical variations of seawater composition, astroparticles and many other things. Our experience in planning, design, realization and management of multidisciplinary experiments in sea waters led us to deal with any aspect of scientific exploration and monitoring of seas: from small mechanical details of the instrumentation to the transfer of huge amounts of data from sea to land, from logistics management of marine operations to scientific data analysis software development.
