“…Autoscala works using input ionograms in a specific binary RDF Pezzopane and Scotto (2005), in which O-and X-mode traces are saved separately. Hence, in order to apply Autoscala to the ionograms recorded by the SGO ionosonde, a change of file format was required.…”

“…One such routine is Autoscala (Pezzopane and Scotto, 2005), which has been developed at the Italian National Institute of Geophysics and Volcanology (INGV) in Rome. Autoscala is a program able to perform an automatic scaling of vertical soundings, giving as output the main ionospheric characteristics Scotto andPezzopane, 2007, 2008; and an estimation of the electron density profile (Scotto, 2009).…”

“…The mid-latitude stations considered to test Autoscala were those of Rome (41.8 • N, 12.5 • E) and Gibilmanna (37.9 • N, 14.0 • E), Italy (Pezzopane and Scotto, 2004, 2005Scotto and Pezzopane, 2007), Moscow (55.5 • N, 37.5 • E), Russia , Warsaw (52.2 • N, 21.1 • E), Poland , Delaware (43.0 • N, 278.8 • E), Canada (Scotto and MacDougall, 2012) and Boulder (40.0 • N, 105.3 • W), Colorado, USA (Bullett et al, 2010). The corresponding results showed that the output given by Autoscala is reliable and accurate and, at times, better than that given by the Automatic RealTime Ionogram Scaling with True-height (ARTIST) system (Reinisch et al, 2009;Galkin and Reinisch, 2008;Scotto, 2005, 2007).…”

Abstract. This paper presents a comparison between standard ionospheric parameters manually and automatically scaled from ionograms recorded at the high-latitude Sodankylä Geophysical Observatory (SGO, ionosonde SO166, 64.1 • geomagnetic latitude), located in the vicinity of the auroral oval. The study is based on 2610 ionograms recorded during the period June-December 2013. The automatic scaling was made by means of the Autoscala software. A few typical examples are shown to outline the method, and statistics are presented regarding the differences between manually and automatically scaled values of F2, F1, E and sporadic E (E s ) layer parameters.We draw the conclusions that:1. The F2 parameters scaled by Autoscala, foF2 and M(3000)F2, are reliable.2. F1 is identified by Autoscala in significantly fewer cases (about 50 %) than in the manual routine, but if identified the values of foF1 are reliable.3. Autoscala frequently (30 % of the cases) detects an E layer when the manual scaling process does not. When identified by both methods, the Autoscala E-layer parameters are close to those manually scaled, foE agreeing to within 0.4 MHz.4. E s and parameters of E s identified by Autoscala are in many cases different from those of the manual scaling. Scaling of E s at auroral latitudes is often a difficult task.

“…The problem of automatic ionogram interpretation is highly complex and consequently the only other widely tested system alongside ARTIST to date is the Autoscala program (Scotto and Pezzopane, 2002), produced by the Istituto Nazionale di Geofisica e Vulcanologia group in Italy. The quality of the data produced by these programs is generally satisfactory for real-time ionospheric monitoring applications, but the reliability of the data is generally considered inferior to that produced by skilled human operators (Pezzopane and Scotto, 2005).…”

Remote Geophysical Observatory in Antarctica with HF Data Transmission: A Review

Abstract:The geophysical observatory in the Antarctic Spanish Station, Juan Carlos I (ASJI), on Livingston Island, has been monitoring the magnetic field in the Antarctic region for more than fifteen years. In 2004, a vertical incidence ionospheric sounder completed the observatory, which brings a significant added value in a region with low density of geophysical data. Although the ASJI is only operative during the austral summer, the geomagnetic station records the data throughout the year. A High Frequency (HF) transmission system was installed in 2004 in order to have the geomagnetic data available during the whole year. As the power supply is very limited when the station is not operative, we had to design a low-power HF transceiver with a very simple antenna, due to environmental aspects. Moreover, the flow of information was unidirectional, so the modulation had to be extremely robust since there is no retransmission in case of error. This led us to study the main parameters of the ionospheric channel and to design new modulations specially adapted to very low signal to noise scenarios with high levels of interference. In this paper, a review of the results of our remote geophysical observatory and associated transmission system in Antarctica during the last decade is presented.
