Phenomena, Observations, and Synthesis Webinar Series
This series will feature experts, with a focus on early career researchers, who are working on research topics of interest to the US CLIVAR Phenomena, Observations, and Synthesis (POS) Panel. The Panel's mission is to improve understanding of climate variations in the past, present, and future, and to develop syntheses of critical climate parameters while sustaining and improving the global climate observing system. The webinars are held on the first Monday of the month @ 1pm ET.

While the Estimating the Circulation and Climate of the Ocean-Darwin (ECCO-Darwin) ocean biogeochemistry state estimate has demonstrated outstanding capabilities in representing space-time variability in global-ocean carbon cycling, it uses a simplified implementation of terrestrial discharge that does not contain biogeochemistry (i.e., carbon and nutrient exports). Land surface or watershed models, coupled with ocean biogeochemical models, now permit quantification of the spatiotemporally-resolved ocean carbon cycle response to riverine fluxes, which can be used to force global ocean biogeochemistry models. In this study, we add lateral fluxes of carbon and nutrients to ECCO-Darwin and evaluate the response of the ocean carbon cycle during 2000–2019. We compute daily riverine biogeochemical export by combining point-source freshwater discharge from JRA55-do with the Global NEWS 2 watershed model, accounting for lateral fluxes from 5171 watersheds worldwide. Globally, the role of present-day riverine exports in ECCO-Darwin results in a source of 0.03 Pg C yr-1 from the ocean to the atmosphere (+1.5%); resulting from significant, compensating regional responses in ocean carbon uptake and outgassing. In carbon-dominated margins, such as the Arctic and Tropical Atlantic Oceans, rivers drive a large source of CO2from the ocean to the atmosphere (+10 and +20%, respectively). However, in nitrogen-dominated margins, such as South-east Asia, rivers drive a large ocean carbon uptake (+9%). Accounting for these critical land-to-ocean processes in ECCO-Darwin represents a major step forward in the development of a holistic, data-constrained modeling framework for monitoring the global carbon cycle, which can be used to support national policy decisions, inform climate resilience strategies for land and marine practices, and evaluate marine carbon dioxide removal (mCDR) strategies.
Process Study Webinar Series
The Process Studies and Model Improvement Panel hosted webinar series aims to provide feedback to process studies. The goals of this webinar series are 1) to provide feedback on the plans and challenges for individual process studies and 2) to distill programmatic lessons from process studies and field campaigns to help current and future observational programs to effectively meet the broader goals of improving the understanding of physical processes in the ocean and the atmosphere and to translate this understanding into improved observational and modeling capabilities. The webinars are typically held on the fourth Tuesday of the month @ 2pm ET.
Predictability, Predictions, and Applications Interface Webinar Series
This series features experts who are working on research topics of interest to the Predictability, Predictions, and Applications Interface (PPAI) Panel. The Panel's mission is to foster improved practices in the provision, validation and uses of climate information and forecasts through coordinated participation within the US and international climate science and applications communities. The Panel members act as facilitators, assisting in moving climate science forward. The webinars are held on the third Wednesday of the month @ 2pm ET.
