PCA-MRM model to forecast TEC at middle latitudes

Anna L. Morozova, Teresa Barata, Tatiana Barlyaeva

The total electron content (TEC) over the Iberian Peninsula was modelled using PCA-MRM models based on decomposition of the observed TEC series using the principal component analys…

Variations of TEC over Iberian Peninsula in 2015 due to geomagnetic storms and solar flares

Anna L. Morozova, Tatiana V. Barlyaeva, Teresa Barata

The total ionospheric content (TEC) over the Iberian Peninsula was studied using data from two locations obtained both by GNSS receivers and an ionosonde. The principal component a…

"SCINDA-Iono" toolbox for MATLAB: analysis of ionosphere scintillations

Tatiana Barlyaeva, Teresa Barata, Anna Morozova

Here we present a "SCINDA-Iono" toolbox for the MATLAB. This is a software to analyze ionosphere scintillation indices provided by a SCINDA GNSS receiver. The toolbox is developed…

Software tool for automatic detection of solar plages in the Coimbra Observatory spectroheliograms

T. Barata, S. Carvalho, I. Dorotovic +4

Full-disk spectroheliograms have been taken in Coimbra on a daily basis since 1926 in the Ca II K-line (K1 and K3). Later, in 1989, with the upgrade of the equipment it was possibl…
