Distinct Ionospheric perturbations such as equatorial plasma bubbles (EPB) and traveling ionospheric disturbances (TID) affect propagation of electromagnetic waves in the ionosphere. Consequently, can be used for their investigation. However, also monitored analysed optically, using airglow emissions OI red line (630 nm) because intensity this emission depends on electron density composition thermosphere, which changes with height.     Simultaneous...
Equatorial Spread F (ESF) events occurring in the post-sunset hours and around postmidnight are studied. Horizontal drift velocities of EPBs calculated from the time lags between signals recorded by different transmitter – receiver pairs a new Continuous Doppler Sounding (CDS) system operating at 6.80 MHz low latitude station, Tucumán, Argentina (26° 49’ S, 65° 13' W, mag. latitude ~13°) older CDS...
Abstract Results of systematic analysis propagation directions and horizontal velocities gravity waves (GWs) spread F structures in low‐latitude ionosphere (magnetic inclination ~27°) Tucumán region, Argentina, are presented. Measurements were carried out by multipoint continuous Doppler system during 1 year from December 2012 to November 2013. It was found that meridian GWs dominated southward prevailed the local summer. Oblique observed shift spectrograms associated with propagated roughly...
SUMMARY The massive explosive eruption of the Hunga volcano on 15 January 2022 generated atmospheric waves that were recorded around globe and affected ionosphere. paper focuses observations in troposphere ionosphere Europe, however, a comparison with East Asia, South Africa America is also provided. Unlike most recent studies based detection changes total electron content, this study builds ionospheric motions at specific altitudes using continuous Doppler sounding. In addition, much...
The Latin American Giant Observatory (LAGO) is a ground-based extended cosmic rays observatory designed to study transient astrophysical events, the role of atmosphere on formation secondary particles, and space-weather-related phenomena. With use network Water Cherenkov Detectors (WCDs), LAGO measures particle flux, consequence interaction astroparticles impinging Earth. This flux can be grouped into three distinct basic constituents: electromagnetic, muonic, hadronic components. When...
In this work, we evaluate the SUPIM-INPE model prediction of 14 December 2020, total solar eclipse over South American continent. We compare predictions with data from multiple instruments for monitoring ionosphere and different obscuration percentages (i.e., Jicamarca, 12.0°S, 76.8°W, 17%; Tucumán 26.9°S, 65.4° W, 49%; Chillán 36.6°S, 72.0°W; Bahía Blanca, 38.7°S, 62.3°W, reach 95% obscuration) due to eclipse. The analysis is done under conditions non-total conditions. Results obtained...

These interactions yield flux particles that can be grouped into three distinct basic constituents:...
In March 2019 a Space Weather Laboratory was deployed at Marambio base in the Antarctic Peninsula. The main instrument installed cosmic ray detector based on water Cherenkov radiation. This is first permanent node of LAGO Collaboration (Latin American Giant Observatory). Project an extended Astroparticle Observatory and it mainly oriented to basic research three branches physics: Extreme Universe,Space phenomena, Atmospheric Radiation ground level. program directed towards study how...
Atmospheric conditions affect the development of cascades secondary particles produced by primary cosmic rays. Global Data Assimilation System, implementing atmospheric models based on meteorological measurements and numerical weather predictions, could significantly improve outcomes simulations for extensive air shower. In this work, we present a methodology to simulate effect in particle flux at Earth's surface. The method was implemented Bucaramanga-Colombia, using ARTI: complete...
Solar activity was intense in September 2017 and its effects were observed different detectors placed at the Earth's surface. Three halo Coronal Mass Ejections (CME) hit planet caused magnetic storms.

In this paper we present detection Forbush events during month 2017. This WCD installed campus University Campinas, Brazil, having...
The aim of this work is to present a global ionospheric prediction model based on deep learning (DL) forecast Total Electron Content 24 hours in advance under different space weather conditions. Three DL techniques have been compared select the most suitable for purpose an operational service: Long Short Term Memory (LSTM), Gated Recurrent Units (GRU) and Convolutional Neural Networks (CNN). modeling approach inherits extends what has proposed by Cesaroni co-authors (2020). We use TEC 18...
