Session 5: Recent Campaigns and New Developments in Observations and Modelling

Co-Chairs: David Tarasick, Nicolas Huneeus

This session aims to facilitate the integration of new observations and new analyses in atmospheric chemistry research, which will promote scientific understanding, inspire further investigation and collaboration, identify critical issues and support prediction and decision-making for global sustainability.  We invite submissions presenting new observations, especially those that challenge current understanding and stimulate further investigation. We welcome contributions discussing the numerical analysis of data from observations and models, model evaluation against observations, data assimilation and application for prediction, and machine learning.  All types of observation are in scope, from the surface to the upper atmosphere, across multiple spatial and time scales. We also welcome studies of new methodological developments in measurement and theory, including physical, chemical, and statistical models.
