"To capture the interrelated research amongst these projects, the special issue is set up jointly between Atmospheric Chemistry and Physicsand Earth System Dynamics. In ACP, we invite papers that emphasize process-level understanding and stratospheric dynamics; in ESD, submissions on Earth system effects, feedbacks, and impacts (like agriculture or ecosystem responses) are invited."

(2020): Comparing different generations of idealized solar geoengineering simulations in the Geoengineering Model Intercomparison Project (GeoMIP). In Atmospheric Chemistry and Physics (under review). DOI: 10.5194/acp-2020-732.

"Two generations of models in the Geoengineering Model Intercomparison Project (GeoMIP) have now simulated offsetting a quadrupling of the CO₂ concentration with solar reduction. This simulation is artificial and designed to elicit large responses in the models. Here we show that energetics, temperature, and hydrological cycle changes in this experiment are statistically indistinguishable between the two ensembles."

"This session solicits contributions from participants who have interest and expertise in measurements and modeling of the Earth System that can be applied to Carbon Dioxide Removal and Solar Radiation Management. Through linking these fields in this session, current technologies and ideas will be shared in both realms, promoting further scientific understanding of geoengineering implications."
