The paper reviews the current state of GNSS-based detection, monitoring and forecasting ionospheric perturbations in Europe relation to COST action ES0803 "Developing Space Weather Products Services Europe". weather research related studies require broad international collaboration sharing databases, developing analysis software models providing services. Reviewed is European GNSS data basis including services derived products such as Total Electron Content (TEC) radio scintillation indices....
This paper presents a review on the PECASUS service, which provides advisories enhanced space weather activity for civil aviation. The are tailored according to Standards and Recommended Practices of International Civil Aviation Organization (ICAO). Advisories disseminated in three impact areas: radiation levels at flight altitudes, GNSS-based navigation positioning, HF communication. review, is based experiences authors from two years running pilot ICAO services, describes empirical models...
Abstract During Solar Cycle 24, which started at the end of 2008, Sun was calm, and there were not many spectacular geoeffective events. In this article, we analyze geomagnetic storm that happened on 15 July 2012 during 602nd anniversary Polish Battle Grunwald, thus propose event to be called “Battle Grunwald Day Storm”. According NOAA scale, it a G3 with southward component heliospheric magnetic field, $Bz$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>B</mml:mi>...
In the frame of European COST 296 project (Mitigation Ionospheric Effects on Radio Systems, MIERS) in Working Package 1.3, new ionospheric models, prediction and forecasting methods programs as well imaging techniques have been developed. They include (i) topside ionosphere meso-scale irregularity (ii) improved for real time foF2, M(3000)F2, MUF TECs, including use such Neurofuzzy, Nearest Neighbour, Cascade Modelling Genetic Programming (iii) dynamic high latitude models through tomographic...
We study intense geomagnetic storms ( Dst < −100nT) during the first half of solar cycle 24. This type storm appeared only a few times, mostly associated with southwardly directed heliospheric magnetic field Bz . Using various methods such as self-organizing maps, statistical and superposed epoch analysis, we show that right after storms, there is growth in number transmission line failures. also examine temporal changes failures 2010-2014 find growing linear tendency electrical grid...
Under Horizon 2020, the Europlanet 2020 Research Infrastructure (EPN2020-RI) will include an entirely new Virtual Access Service, "Planetary Space Weather Services" (PSWS) that extend concepts of space weather and situational awareness to other planets in our Solar System particular spacecraft voyage through it. PSWS make twelve services accessible research community, agencies, industrial partners planning for missions. These be dedicated following key planetary environments: Mars (in...
We are concerned with the time series resulting from computed local horizontal geoelectric field, obtained aid of a 1-D layered Earth model based on geomagnetic field measurements, for full solar magnetic cycle 1996-2019, covering two consecutive activity cycles 23 and 24. To our best knowledge, first time, roughness severe storms is considered by using monofractal analysis electric field. show that during Katz fractal dimension grows rapidly.
This paper presents comparisons of variability and accordance ionospheric parameters foF2, hmF2, M3000F2, B0, B1 over the middle latitude station in Warsaw (52.21°N, 21.06°E). Examination included observational data from Space Research Centre ionosonde Poland International Reference Ionosphere (IRI) 2012 model, for time period increasing solar activity 2009 to 2012. The analysis concerned: trend, monthly median differences twenty-four hours variability, local minima maxima. Results are...
The main objective of the COST 296 Action «Mitigation Ionospheric Effects on Radio Systems» is establishment/ improvement ionospheric services by coordinating development specific algorithms, models, and tools capable operating in a near-real-time mode. Key elements these activities are contributions related to monitoring, modelling, imaging customer-relevant quantities. stimulates, coordinates, supports Europe’s goals global cooperation providing high quality information knowledge...
Abstract The European Geostationary Overlay Service (EGNOS) augments Global Positioning System (GPS) by providing correction data and integrity information for improving positioning over Europe. EGNOS Performance Monitoring Support (SPMS) project has assumed establishment, maintenance implementation of an performance monitoring network. paper presents preliminary results analyses prepared in Space Research Centre, Polish Academy Sciences (Warsaw), as one partners SPMS project.
ABSTRACT Since 2017, the Space Research Centre of Polish Academy Sciences in Warsaw, Poland, has measured and gathered over 35,000 hours observations with use LOw Frequency ARray (LOFAR) radio telescope. This paper outlines Standard Data Product acquired from LOFAR PL610 station located Borówiec, Poland. Within this context, we detail data products that are accessible, provide metadata descriptions for them, include an example under both quiet disturbed ionospheric conditions.
The galactic cosmic ray (GCR) flux recorded by neutron monitors on the ground and space probes provides persistent information about events originating from Sun. In this study, we examine time periods of sporadic Forbush decreases that occurred during rising phase 24th solar cycle. We analyze various parameters related to solar, heliospheric, geomagnetic activity these periods, using different machine learning techniques. also calculate geoelectric field in Poland region for period a 1-D...
With its Planetary Space Weather Service (PSWS), the Europlanet-H2020 Research Insfrastructure (EPN2020RI) project is proposing a compelling set of databases and tools to that provides forecasting throughout Solar System.

HF radio waves can propagate on the long distances with low losses due to reflection from ionospheric plasma. This feature of is used organize a communication over distances. Ionospheric channel bandwidth relatively narrow (in order several kilohertz). However, quite simple use, inexpensive and very reliable. During failure satellite systems remains operational, since it depends only Sun Earth's atmosphere. The plasma nonuniform nonstationary medium. Therefore, propagation conditions are...
LOFAR is valuable tool not only for astronomical observation. I Poland was located 3 stations.
