calendar_today Is the coastal ocean an increasing CO2 sink for the atmosphere?

person Formal Seminar (approved) - Formal Seminar - Wei-Jun Cai (University of Delaware)

access_time 2:00 pm - 3:00 pm

place Location: Smagorinsky Seminar Room

The ocean takes up about 30% of anthropogenic CO2 (about 1.5 PgC/yr from direct air-sea CO2 gradient data plus perhaps another 0.6 PgC/yr background flux). It only becomes clear in the last 10-15 years that the coastal ocean is also a CO2 sink (about 0.2 PgC/yr), which has demonstrated strong regional variability. In this talk I will review sea surface pCO2 and carbonate chemistry data in the global coastal oceans with a focus on the North American margins and discuss the control mechanisms of pCO2, pH and carbonate saturation state distributions in a few better measured regions. While data spans are still quite limited (within 10-20 years in most regions), we are able to demonstrate the highly variable rates of pCO2 change (different than the atmospheric CO2 increase rate) and ocean acidification in various regions. Based on a conceptual model and limited data, I will argue that the coastal ocean is an increasing CO2 sink for the atmosphere and that it will contribute more to the global ocean acidification via cross-margin export of dissolved inorganic carbon to the open ocean.

calendar_today Progress in quantifying the effective radiative forcing due to aerosol-cloud interactions

person Lunchtime Seminar - Lunchtime Seminar Series - Johannes Quaas (Universität Leipzig, Institute for Meteorology, Leipzig University, Germany)

access_time 12:00 pm - 1:00 pm

place Location: Smagorinsky Seminar Room

The effective radiative forcing due to aerosol-cloud interaction, ERFaci, is composed of the radiative forcing due to aerosol-cloud interactions, RFaci (Twomey effect) that is the immediate response of cloud albedo to an increase in droplet number concentration, Nd. Previous satellite-based quantifications of this effect were hampered by deficiencies in the retrieval of aerosol and also Nd. The talk will firstly discuss progress in this regard, which leads to a stronger estimated RFaci than previous satellite-based approaches. The other component of ERFaci is in the cloud adjustments. These can be split into adjustments of cloud fraction, f, and liquid water path, L. In terms of the latter, statistical relationships between L and Nd show on average negative adjustments of L (a positive forcing component). In turn, the analysis of ship-, volcano- and industry tracks leads to an estimated small overall effect on L; these results are trustworthy since a cause-effect relation is assured. In terms of the f adjustment, the current results point to an increase in cloud fraction at larger Nd. It is unclear which processes lead to this result. The talk will also briefly discuss how cloud-resolving simulations may help to better understand the remaining uncertainties. In the last part, a brief discussion will be presented on initial steps towards an estimate of the response of cirrus to anthropogenic aerosols.
