Total electron content PCA-NN model for middle latitudes
Anna Morozova, Teresa Barata, Tatiana Barlyaeva +1
A regression-based model was previously developed to forecast the total electron content (TEC) at middle latitudes. We present a more sophisticated model using neural networks (NN)…
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…
Principal component analysis as a tool to extract Sq variation from the geomagnetic field observations: conditions of applicability
Anna Morozova, Rania Rebbah
In this paper, we analyze the applicability of the principal component analysis (PCA) as a tool to extract the Sq variation of the geomagnetic field. We tested different geomagneti…
Comparison of the solar variations of the geomagnetic field at the Coimbra Magnetic Observatory (COI) obtained by different methods: effect of the solar and geomagnetic activity
Anna Morozova, Rania Rebbah
Here we present the results of the comparative analysis of the regular daily variations of the geomagnetic field, Sq and SD, obtained from the observations with two methods: (1) us…
Datasets of the solar quiet (Sq) and solar disturbed (SD) variations of the geomagnetic field from the mid latitudinal Magnetic Observatory of Coimbra (Portugal) obtained by different methods
Anna Morozova, Rania Rebbah, Paulo Ribeiro
Here we present datasets of daily variation obtained from the geomagnetic field raw observations recorded at the Coimbra Magnetic Observatory (COI, Portugal) in 2007-2017, covering…
Datasets of ionospheric parameters provided by SCINDA GNSS receiver from Lisbon airport area
Tatiana Barlyaeva, Teresa Barata, Anna Morozova
Here we present datasets provided by a SCINDA GNSS receiver installed in the Lisbon airport area from November of 2014 to July of 2019. The installed equipment is a NovAtel EURO4 w…
