EaSM Project at CASCADE, NEU
Two EaSM projects are ongoing at NEU under the research program entitled Decadal and Regional Climate Prediction using Earth System Models established by NSF, USDA, and US DOE.
The first project is jointly sponsored by NSF and USDA. It is a collaborative effort among NEU, ANL, and USDA Forest Service to estimate the decadal impacts of global climate changes on the global-through-urban earth system, including air quality, water quality/supply, and forest carbon and nitrogen cycles, using an innovative technology-driven earth system model in support of air quality and agro-ecosystem policy analyses and management planning. In this project, we will develop an Earth system model to link energy, emissions, climate, air quality, water quality, ocean, forest, land, and ecosystems, simulate their interactions, conduct decadal simulations for current/future year climate and emission scenarios, and quantify the mutual effects of global changes driven by human activities and natural variabilities on the Earth System. This project aims at improving our understanding of the coupled interactive physical, chemical, biological and human processes that drive the climate system and reducing uncertainties in projecting future climate changes and associated impacts.
The second project is sponsored by DOE. It is a collaborative effort among NEU and PNNL to address the critical need for an accurate representation of aerosol indirect effect in climate and Earth system models. In this project, we will improve parameterizations for convective clouds, ice nucleation formation, aerosol chemistry and miscrophysics, and aerosol-cloud interactions. We will use East Asia as a testbed to evaluate the improved model representation at a fine grid scale. This project aims at improving climate models or components of Earth System Models by enhancing the model representations of aerosols, clouds, and precipitation.
