Goals and objectives: To understand the impact of the Sun on the terrestrial middle atmosphere/lower thermosphere/ionosphere (MALTI) and Earth‘s climate and its importance relative to anthropenic forcing over various time scales from minutes to centuries.
Data/theory/modeling: Use existing data records plus new measurements from a wide range of ground based, in–situ, and space–based instruments. use/develop dedicated models for a better understanding of specific processes (e.g. gravity wave breaking, ice formation). Modify and apply global–scale models from the ocean to the thermosphere.
Anticipated outcome: Better understanding of the impact of solar activity on the entire atmosphere, relative to anthrogenic forcing and natural long term variability
