The first part of this paper reviews methods using effective solar indices to update a
background ionospheric model focusing on those employing the Kriging method to perform …

This paper aims at providing an overview of latest advances in space weather modeling in
an operational environment in Europe, including both the introduction of new models and …

To further improve the quantitative forecasting ability of high-frequency (HF) communication
frequency, we propose a maximum usable frequency (MUF) adaptive forecasting method …

Characteristics of midlatitude ionospheric disturbances during several great geomagnetic
storms have been investigated using data from the European geomagnetic observatories …

A method for map** of ionospheric conditions over Europe, suitable to be used in real
time for operational applications, is described in this paper. The method is based on the …

The dynamics of ionospheric parameters forecasting and nowcasting are actual and rather
challenging tasks. The feature selection is the principal challenge for the accurate …

The main objective of DIAS (European Digital Upper Atmosphere Server) project is to
develop a pan-European digital data collection on the state of the upper atmosphere, based …

The simplified ionospheric regional model (SIRM) was originally developed for modeling the
most relevant ionospheric characteristics over Europe for radiocommunication purposes …

Knowledge of the state of the upper atmosphere, and in particular its ionospheric part, is
very important in several applications affected by space weather, especially the …

Our objective is to review recent advances in ionospheric and thermospheric modeling that
aim at supporting space weather services. The emphasis is placed on achievements of …
