“…The evaluation of the spectra and the basic statement of the model have been discussed by Velinov et al (2011aVelinov et al ( , 2011bVelinov et al ( , 2012. In the case with six characteristic energy intervals we reach the accuracy which is in accordance with experimental data (Brasseur & Solomon 2005;Velinov & Mateev 2008a. The model can be applied for different input spectra in interactive mode and for different planetary atmospheres.…”

“…This model was applied for calculation of electron density and atmospheric electrical conductivities in the middle atmosphere for different particles: GCR, ACR and SEP. The intermediate target ionization model was further developed with account of the Chapman function values for the inclined penetrating particles in the spherical atmosphere (Velinov & Mateev 2008aVelinov et al , 2009.…”

A brief review of the study during COST Action ES0803 of effects due to cosmic rays (CR) and solar energetic particles (SEP) in the ionosphere and atmosphere is presented. Models CORIMIA (COsmic Ray Ionization Model for Ionosphere and Atmosphere) and application of CORSIKA (COsmic Ray SImulations for KAscade) code are considered. They are capable to compute the cosmic ray ionization profiles at a given location, time, solar and geomagnetic activity. Intercomparison of the models, as well as comparison with direct measurements of the atmospheric ionization, validates their applicability for the entire atmosphere and for the different levels of the solar activity. The effects of CR and SEP can be very strong locally in the polar cap regions, affecting the physical-chemical and electrical properties of the ionosphere and atmosphere. Contributions here were also made by the anomalous CR, whose ionization is significant at high geomagnetic latitudes (above 65°-70°). Several recent achievements and application of CR ionization models are briefly presented. This work is the output from the SG 1.1 of the COST ES0803 action (2008)(2009)(2010)(2011)(2012) and the emphasis is given on the progress achieved by European scientists involved in this collaboration.

“…Theyconsidered only ionization losses of the primary cosmic ray particles and neglected nuclear interactions in the middle atmosphere above 30 km (upper stratosphere and ionosphere) [14,26];. In addition, they further neglect changes of energetic particles for the altitude above 50 km, thus, reducing the computation of cosmic ray ionization to an analytical thin target model [65,67,68]. At the altitude ranging from 25-30 to 50 km, an intermediate target model needs to be applied which accounts for the particle's deceleration due to ionization losses [66].…”

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 improvements to existing codes and algorithms that address the broad range of space weather's prediction requirements from the Sun to the Earth. For each case, we consider the model's input data, the output parameters, products or services, its operational status, and whether it is supported by validation results, in order to build a solid basis for future developments. This work is the output of the Sub Group 1.3 ''Improvement of operational models'' of the European Cooperation in Science and Technology (COST) Action ES0803 ''Developing Space Weather Products and services in Europe'' and therefore this review focuses on the progress achieved by European research teams involved in the action.
