    Application of Autoscala to ionograms recorded by the VIPIR ionosonde (2010)
    Elsevier
    Details
    Publication Date: 2020-12-02
    Description: 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.

    Highlighting the F2 trace on an ionogram to improve Autoscala performance (2010)
    Elsevier
    Details
    Publication Date: 2017-04-04
    Description: This work describes a linear regression based method for highlighting the cuspidal trace on an ionogram. This method was initially thought to smooth out cases in which the autoscaling of the ionogram performed by Autoscala was erroneous because the F2 ordinary ray was identified as the extraordinary ray. Actually the development of this method turned out to also be very useful for filtering out noise and assisting the main algorithm of Autoscala to not be misled by multiple-hop sporadic E layer echoes. Applying the algorithm to different ionograms recorded by different ionosondes showed that the application of this method considerably improved the Autoscala performance. The role that this method plays in the light of existing algorithms is also discussed.

    Application of Autoscala to ionograms recorded by the AIS-Parus ionosonde (2010)
    Elsevier
    Details
    Publication Date: 2019-12-09
    Description: Autoscala was applied to ionograms recorded by the digital AIS-Parus ionosonde, built at the Pushkov Institute of Terrestrial Magnetism,Ionosphere and Radiowave Propagation, Russia, and installed in Moscow (55.5N,37.5E). Some results in regard to the reliability of the foF2, foF1, and ftEs autoscaled characteristics are presented and discussed. The flexibility of Autoscala is illustrated based on its modular structure.

    COST 296 action results for space weather ionospheric monitoring and modelling (2010)
    Elsevier
    Details
    Publication Date: 2017-04-04
    Description: COST 296 Action refers to the project on Mitigation of Ionospheric Effects on Radio Systems (MIERS) in the framework of European Cooperation in Science and Technology (COST), which is one of the longest-running European instruments supporting cooperation among scientists and researchers across Europe. The main objective of the MIERS project has been to develop an increased knowledge of the effects imposed by the ionosphere on practical radio systems, and for the development and implementation of techniques to mitigate the harmful effects of the ionosphere on such systems. This paper highlights COST 296 Action results that have been achieved during its lifetime period of February 2005–February 2009 with emphasis on space weather ionospheric monitoring and modelling
