    Beschreibung: In November 2008, the ionosonde station at Boulder, Colorado, USA (40.0°N; 105.3°W) became the host of a new ionosonde (VIPIR, Vertical Incidence Pulsed Ionospheric Radar) developed and built by Scion Associates. The VIPIR is a fully digital frequency agile radar that operates between 0.3 and 26 MHz. It features 8 digital receivers and a digital transmit exciter. Extremely high performance analog receive electronics and a 4 kW solid state amplifier provide interface to the real world. This work describes the application of Autoscala to the ionograms recorded by this ionosonde. First results, in terms of ionograms and autoscaled characteristics, are presented and discussed.

    Beschreibung: The performance of a computer program, called Autoscala, for the automatic scaling of foF2 and MUF(3000)F2 from ionograms has been extensively tested. Results of comparisons between automatically and manually scaled data are shown both for Autoscala and for ARTIST (release 4.01). Particular attention has been paid to the cases in which the ionograms have a truncated trace. The problem of the rejection of bad quality ionograms has been also considered. The analysis of data shows that the reliability of values automatically given as output by Autoscala is good. For the data set considered Autoscala seems to operate better than ARTIST.

    Beschreibung: The ionospheric community has long been aware that co-operative research on an international basis is essential to deal with temporal and spatial changes in the ionosphere that influence the performance of terrestrial and Earth-space radio systems. The EU COST (Cooperation in the field of Scientific and Technical Research) 271 Action on "Effects of the Upper Atmosphere on Terrestrial and Earthspace Communications" has had during the period of October 2000-August 2004 the following main objectives: (1) to evaluate the influence of upper atmospheric conditions on terrestrial and Earth-space communications, (2) to develop methods and techniques to improve ionospheric models over Europe for telecommunication and navigation applications and (3) to transfer the results to the appropriate radiocommunication study groups of the International Telecommunication Union (ITU-R) and other national and international organizations dealing with the modern communication systems. At the beginning of 2005 the new 296 Action in the COST Telecommunications, Information Science and Technology domain on "Mitigation of lonospheric Effects on Radio Systems (MIERS)" was approved for the period 2005-2009. The main objectives of the MIERS are: (a) to support and enhance the existing European facilities for historical and real-time digital ionospheric data collection and exchange; (b) to develop an integrated approach to ionospheric modelling, create the mechanism needed to ingest processed data into models, extend and develop suitable mitigation models and define the protocols needed to link models together; and (c) to strengthen the areas of expertise that already exist by stimulating closer cooperation between scientists and users, focusing the scope of all the previous COST ionospheric related studies to the mitigation of ionospheric effects on radio systems. This paper summarises briefly how the major objectives of the COST27l Action have been achieved and what are the most important activities to be undertaken in the follow-on COST296 Action.

    Beschreibung: COST (Co-operation in the field of Scientific and Technical Research) is an important instrument supporting co-operation among scientists and researchers across Europe now joining 35 member countries. Scientific projects in the COST framework are called COST Actions and have the objectives embodied in their respective Memorandum of Understanding (MoU). The main objectives of the COST Actions within the European ionospheric and radio propagation community have been: to study the influence of upper atmospheric conditions on terrestrial and Earthspace communications, to develop methods and techniques to improve existing and generate new ionospheric and propagation models over Europe for telecommunication and navigation applications and to transfer the results to the appropriate national and international organizations, institutions and industry dealing with the modern communication systems. This paper summarises in brief the background and historical context of four ionospheric COST Actions and outlines their main objectives and results. In addition, the paper discusses the dissemination of the results and the collaboration among the participating institutions and researchers.

    Beschreibung: By analysing an ionogram several important parameters like foF2 and MUF(3000)F2 can be found, that have a significant role in the studies concerning ionospheric physics and related phenomena. Furthermore, the observation of ionospheric plasma and the forecasting of physical phenomena connected to the Sun-Magnetosphere–Ionosphere–Thermosphere system holds a remarkable scientific interest with respect to space weather, because of the influence that these phenomena have on satellite and terrestrial communications. From this point of view, the development of models whose input are real-time ionospheric parameters has become fundamental. This paper will introduce a Visual Basic program for semi-automatic scaling of ionospheric parameters from ionograms. This software allows to increase the speed of the scaling phase performed by the operator trying also to improve the output in terms of reliability.

    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.

    Beschreibung: By analyzing an oblique ionogram several characteristics, such as LOF, MOF, FMUF, FHLOF, FLLOF, and 2FMOF, can be found. These characteristics are important both for ionospheric studies and for terrestrial communication purposes, as they give information about the sky wave communication conditions in the High Frequency (HF) radio spectrum. A RCS-5B sweeping HF receiver for oblique sounding was installed at Chania (Crete, Greece, 35.71N, 24.01E) in April 2005 to perform a radio link with Inskip (UK, 53.51N, 2.51W). The receiver, able to record the sounding only as a binary file, was not equipped with a tool to display and scale the recorded trace. This work describes software that is able to do this, consequently increasing the speed of the scaling phase performed by the operator. The usefulness of this software for validating FMUF prediction models is also shown.

    Beschreibung: The current COST (Co-operation in the field of Scientific and Technical Research) Action 296 on Mitigation of Ionospheric Effects on Radio Systems, along with previous COST238 (Prediction and Retrospective Ionospheric Modelling over Europe), COST251 (Improved Quality of Service in Ionospheric Telecommunication Systems Planning and Operation) and COST271 (Effects of the Upper Atmosphere on Terrestrial and Earth-Space Communications) Actions have addressed investigations of the different effects of the ionosphere on terrestrial telecommunication systems and on Earth-space systems. Throughout their lifetime of 20 years, these COST actions have achieved a great deal in long-term archiving of synoptic soundings of the state of the ionosphere, in enhancing understanding of the morphology of the ionosphere and its dependence on space weather and in producing ionosphere-plasmasphere as well as propagation models for terrestrial radio services available to variety of radio users. Besides the formal contributions to ITU-R and the contributions to international organisations such as URSI, COSPAR, EGU and ESA, these COST Actions have provided a forum for the establishment of collaborative European initiatives, a centre of expertise and excellence in ionosphere knowledge when none other equivalent in Europe or elsewhere exists. In this paper, we review the main achievements of the COST 238, 251 and 271 actions as developed in the past studies.

    Beschreibung: This work describes a simple filter able to eliminate the traces caused by second order reflection from ionograms. This filter is applied to Autoscala in order to smooth out cases in which the autoscaling of the ionogram is mistaken because the second order F2 layer reflection is identified as first order. A dataset of 32626 ionograms recorded at the ionospheric observatory of Rome was used to test the filter.
