The ocean-atmosphere boundary is the crucial setting for a range of processes with significant impacts on oceanography, atmospheric and climate science. The international Surface Ocean Lower Atmosphere Study (SOLAS) program, now beginning to implement its third decadal science plan, promotes collaboration and interdisciplinary research within and across this boundary. A particularly important process is the air-sea gas exchange of CO2, which results in approximately 25% of anthropogenic CO2 emissions being absorbed by the ocean, lessening atmospheric accumulation and fueling ocean acidification. The Surface Ocean COâ‚‚ Mapping intercomparison initiative (SOCOMv2) addresses challenges in quantifying the ocean carbon sink, an effort compatible with SOLAS goals. In addition, SOLAS research also includes investigating the feedbacks between atmospheric and marine chemistry, aerosol exchange and impact, sea-surface microlayer processes, and ocean-sea ice-snow-atmosphere interactions. This session seeks contributions that highlight recent research achievements related to any of the SOLAS and SOCOMv2 themes, particularly observational, machine learning and modeling studies of processes linking the surface ocean and the lower atmosphere. Advancements associated with improving quantification of global and regional air-sea COâ‚‚ fluxes and the ocean carbon sink are especially relevant. However, any research examining the SOLAS domain, regardless of its SOLAS or SOCOMv2 affiliation, is welcome.
