    • Correlation studies for B-spline modeled F2 Chapman parameters obtained from FORMOSAT-3/COSMIC data 

      Limberger, Marco; Liang, W; Schmidt, Michael; Dettmering, D; Hernández Pajares, Manuel; Hugentobler, U (2014)
      Article
      Open Access
      The determination of ionospheric key quantities such as the maximum electron density of the F2 layer NmF2, the corresponding F2 peak height hmF2 and the F2 scale height HF2 are of high relevance in 4-D ionosphere modeling ...
    • Evaluation of the ionospheric F2 characteristics inferred from radio occultations exploiting the availability of FORMOSAT-3/COSMIC data over half a solar cycle 

      Aragón Ángel, Maria Angeles; Limberger, Marco; Hernández Pajares, Manuel; Altadill, David; Erdogan, Eren; Schmidt, Michael (ION Publications (The Institute of navigation), 2016)
      Conference report
      Restricted access - publisher's policy
      This contribution presents the assessment, on both the maximum electron density (NmF2) and the corresponding peak height of the F2 layer (hmF2), of the overall performance of such ionospheric key parameters inferred from ...
    • Ionosphere monitoring and forecast activities within the IAG working group “Ionosphere Prediction” 

      Hoque, Mainul; García Rigo, Alberto; Erdogan, Eren; Cueto, M.; Jakowski, Norbert; Berdermann, Jens; Hernández Pajares, Manuel; Schmidt, Michael; Wilken, Volken (2017)
      Conference lecture
      Open Access
      Ionospheric disturbances can affect technologies in space and on Earth disrupting satellite and airline operations, communications networks, navigation systems. As the world becomes ever more dependent on these technologies, ...
    • Real time global ionospheric maps: a low latency alternative to traditional GIMs 

      Roma Dollase, David; Hernández Pajares, Manuel; García Rigo, Alberto; Laurichesse, Denis; Schmidt, Michael; Erdogan, Eren; Yuan, Yunbin; Li, Zishen; Gómez-Cama, José Ma.; Krankowski, Andrzej (2016)
      Conference lecture
      Restricted access - publisher's policy
      Since the late nineties different entities have been generating and distributing Global Ionospheric Maps (GIMs). In this time, multiple new application have arisen from the determination of electron content distribution ...
    • Recent activities of IAG working group “Ionosphere Prediction” 

      Erdogan, Eren; Hoque, Mainul; García Rigo, Alberto; Cueto, M.; Schmidt, Michael; Jakowski, Norbert; Berdermann, Jens; Monte Moreno, Enrique; Hernández Pajares, Manuel (2018)
      Conference lecture
      Open Access
      Ionospheric disturbances pose, for instance, an increasing risk on economy, national security, satellite and airline operations, communications networks and the navigation systems. Constructing ...
    • Towards an optimal overall description of electron density information gathered during GNSS satellite occultations 

      Olivares Pulido, Germán; Hernández Pajares, Manuel; Limberger, Marco; García Rigo, Alberto; Aragón-Angel, Angela; Schmidt, Michael; Hugentobler, U (2014)
      Conference lecture
      Restricted access - publisher's policy
      The purpose of this work is to characterize the performance of different interpolation methods in order to build a global model of ionospheric free electron density, directly derived from the inversions of GNSS occultation ...
