The statistical correlations of rate of change of TEC index (ROTI) on the standard scintillation indices over the Canadian Arctic

Frontiers in Astronomy and Space Sciences
For decades, the Rate of Change of Total Electron Content Index (ROTI) has been employed to monitor and quantify ionospheric irregularities, serving as a potential substitute for standard scintillation indices.

Software Holography: Interferometric Data Analysis for the Challenges of Next Generation Observatories

, 2008
Next generation radio observatories such as the MWA, LWA, LOFAR, CARMA and SKA provide a number of challenges for interferometric data analysis. These challenges include heterogeneous arrays, direction-dependent instrumental gain, and refractive and ...

Tackling ionospheric scintillation threat to GNSS in Latin America

Journal of Space Weather and Space Climate, 2011
Scintillations are rapid fluctuations in the phase and amplitude of transionospheric radio signals which are caused by small-scale plasma density irregularities in the ionosphere.

Probing the Climatological Impact of a Cosmic Ray-Cloud Connection through Low-Frequency Radio Observations

, 2011
It has been proposed that cosmic ray events could have a causal relationship with cloud formation rates. Given the weak constraints on the role that cloud formation plays in climate forcing it is essential to understand the role such a relationship could
