National Center for Atmospheric Research (NCA)
Katie Dagon What to Expect A machine learning approach to quantify climate model uncertainty. Climate models are essential tools for understanding and predicting Earth system processes and feedbacks, but uncertainties in their future projections remain challenging to characterize. This talk will present a machine learning approach to quantify the contribution of land model parameters to overall climate model uncertainty. Using a perturbed parameter ensemble of land surface model simulations, Katie trains a neural network to predict model output given a…

Assessing Past and Projected Drought Patterns In Central America’s Northern Triangle Region
Nicholas Depsky, MS What to Expect Central America’s Northern Triangle has periodically faced severe droughts in the past, which have had a range of socio-economic impacts. This study aims to understand both the historical and projected changes in drought patterns in Guatemala, El Salvador, and Honduras at both the national and department-levels. This analysis uses a purely meteorological definition of drought, with deficits in rainfall identified by via the Standardized Precipitation Index (SPI) at multiple time-scales (3, 6, 9 and…

Non-stationary Climate Dynamics Pose Challenges to Engineers and Hydrologists in the Design of Infrastructure, the Development of Economic Tools
James Knighton What to Expect Non-stationary climate dynamics pose challenges to engineers and hydrologists in the design of infrastructure, the development of economic tools to hedge against changing environmental risks, and restoration of ecosystems. The forecasts necessary to address future water resources problems require an understanding of thermodynamic intensification of precipitation, structural atmospheric changes, shifts in plant compositions and phenologies, and knowing whether our current hydrologic models are flexible enough to capture these processes. In this talk, Dr. Knighton will…

Atmospheric rivers in the Atlantic Ocean
Alexandre M. Ramos, Assistant Researcher Instituto Dom Luiz – Universidade de Lisboa The speaker has more than 15 years of experience in climate research, in extra-tropical cyclones, heatwaves, precipitation impacts, and climate change. I participated in more than 13 national and international projects. My research is now focused on the Atmospheric Rivers variability in Atlantic Basin and their influence in adjacent costal regions. Currently I am a Leader of Working Package 1 of the DOMACLES COST action (compound event project). In…

To Be Rescheduled: You can’t always get what you want–a tale of two research projects
EESA will host a DSSS lecture on October 11 in Building 66. Albert J. Valocchi focuses on modeling of pollutant fate and transport in porous media, with applications to groundwater resource sustainability, groundwater contamination, geological sequestration of carbon dioxide, and impacts of model uncertainty on groundwater resource management.

Climate Brown Bag: The role of plant traits and global change on ecosystem functioning across Mediterranean-type ecosystems
Successful restoration towards a long-term supply of ecosystem services requires a fundamental understanding of the link between ecosystem composition, related ecosystem functions and services, and influencing environmental factors. Measurable plant traits have been recognized as such a link. Until now, however, trait-based research to reliably support restoration in Mediterranean-type ecosystems is missing. We started closing this gap by integrating empirical research and process-based simulation modelling. We developed an individual-based eco-hydrological simulation model complementing an ongoing large-scale restoration project in Western…
