Dear Colleagues,
Following our First and Second Call announcements, we are pleased to invite you to participate in the International Scientific Workshop: MNS4A (Modeling, Networks, and Scientific Instrumentation for Aeronomy), focused on "Implications of Natural Hazard Impacts on Aeronomy."
Registration and abstract submission remain open, and we encourage interested researchers to submit their contributions and register for this free event.
Dates: 19–21 October 2026
Location: INPE · São José dos Campos, Brazil
Registration: Completely Free of Charge
Reminder: Abstract submissions will be accepted until 30 August 2026.
About the Workshop
MNS4A bridges fundamental science with real-world applications, bringing together researchers to discuss challenges at the intersection of atmospheric and ionospheric modeling, observational networks, and scientific instrumentation. The workshop aims to discuss recent advances in ionospheric seismology and future directions in the field.
The MNS4A Workshop is jointly organized by INPE and the FAPESP-funded IONO-DIET Project (Grant No. 2022/03502-6), with institutional support from SBGEA. We invite oral and poster contributions for the following sessions:
SESSION 01 · MODELING
Modeling of Atmosphere and Ionosphere Variabilities
In this session, we invite contributions on atmospheric and ionospheric modeling, forecasting, hazard characterization, machine learning, data assimilation, and model-data integration. Studies advancing model capabilities, observational constraints, and understanding of space weather variability are encouraged.
SESSION 02 · NETWORKS
Scientific Networks for Atmosphere and Ionospheric Applications
This session welcomes contributions on open questions in aeronomy, focusing on the role of integrated ground-based and space-based observational networks in advancing our understanding of atmosphere-ionosphere coupling, space weather, and geospace variability. Particular emphasis is placed on current observational gaps, including limited geographic coverage and real-time data availability. The session also encourages discussions on international efforts to expand and coordinate observational infrastructures.
SESSION 03 · INSTRUMENTATION
Scientific Instrumentation and Challenges
This session welcomes contributions on instrument development, operation, maintenance, data acquisition, low-cost alternatives, and intercomparison. Ground-based and space-borne instruments provide complementary observations supporting studies of atmospheric and ionospheric variability and their impacts on infrastructure and society across different spatiotemporal scales.
Participation
MNS4A is an inclusive forum. Early-career researchers are especially encouraged to participate. The scientific committee will actively include emerging voices in oral sessions alongside invited senior scientists.
Registration and abstract submission are open and can be completed through the workshop website: https://www.gov.br/
As this is the Third Call for Participation, we kindly encourage prospective participants to complete their registration and submit their abstracts at their earliest convenience.
Please help us spread the word by sharing this announcement within your institutional networks and social media.
Best regards,
On behalf of the MNS4A Local Organizing Committee
