Are you working on the magnetosphere, ionosphere, atmosphere, or space weather?
We invite members of the scientific, operational, and applied user communities to contribute to a community survey that will help shape a New Earth Observation Mission Idea (NEOMI) Study of Energetic Particle Precipitation (SEEP). Earth’s atmosphere is not isolated from space. Invisible streams of energetic particles constantly connect the near-Earth space environment with our atmosphere, influencing atmospheric chemistry, ozone and NOx, atmospheric dynamics, and even aspects of space weather.
Yet many of the underlying processes remain poorly understood:
How does energetic particle precipitation (EPP) change under different geomagnetic and solar wind conditions?
How do particle precipitation processes couple the magnetosphere, ionosphere, and atmosphere?
What is the role of EPP in long-term atmospheric variability and climate-relevant processes?
These are some of the questions driving NEOMI SEEP, an ESA-funded project exploring the idea for a future Earth observation mission dedicated to the coupled space–atmosphere system. The project is planning a combination of:
In-situ satellite measurements of energetic particles and waves
Simultaneous observations of atmospheric composition (e.g. NOx, ozone)
Synergy with physics-based models to better understand and reconstruct the system
A key aspect of the mission is the integration of observations and modelling, enabling improved interpretation of measurements and reconstruction of conditions during periods without direct observations.
To shape this mission idea, we are inviting the scientific community to contribute to a short survey, Community Survey on Measurement Needs and Applications for the NEOMI SEEP Mission Idea, meaning: you! We want to know your opinion on which scientific questions matter most, which observations are still missing or most valuable, how future measurements could support research, modelling, and operational applications, and what synergies with other observations are needed.

He is currently leading the NEOMI SEEP study supported by ESA’s New Earth Observation Mission Idea programme.
Thank you!
Your feedback will help shape the NEOMI SEEP mission idea and contribute to defining future Earth observation capabilities.
