A Forest for the Trees: Using Random Forests for Small Area Estimation on US Forest Inventory Data
(2023-06-30)Methods which estimate population parameters of interest across small areas is a growing field of research. These problems arise frequently in election prediction, healthcare monitoring, and environmental studies. The ... -
Amazon Forest Response to Changes in Rainfall Regime: Results from an Individual-Based Dynamic Vegetation Model
(2014-02-25)The Amazon is the largest tropical rainforest in the world, and thus plays a major role on global water, energy, and carbon cycles. However, it is still unknown how the Amazon forest will respond to the ongoing changes ... -
Amine-mediated CO2 hydration as a potential carbonic anhydrase alternative in marine Thaumarchaeota
(2021-06-17)Marine Thaumarchaeota are ammonia-oxidizing archaea that make up the predominant group of nitrifiers in the global N cycle and fix bicarbonate (HCO3-) autotrophically via the highly efficient 3-HP/4-HB pathway. Most ... -
Exploring the Limits of Geophysical Models of Solar Geoengineering
(2022-05-13)Solar Radiation Modification (SRM) is a proposed method of reducing climate risks associated with climate change via modification of Earth's radiative budget. Due to the impracticality of global experimentation, research ... -
Fidelity of climate data: Trends, extremes, and nonlinearities in instrumental and tree-growth proxies of climate
(2023-01-12)This work looks at inferences of climate -- and specifically moisture and temperature --, past and present. In the present, asks whether we have enough data to understand extremes in temperature and trends in moisture. ... -
Gas-Particle Interactions of Organic Aerosol
(2021-11-16)Atmospheric organic aerosols play significant roles in climate, air quality, and human health. Quantitative understanding and predicting the gas-particle interactions of organic aerosols and their role in particle formation ... -
Global Modeling of Persistent Organic Pollutants in an Era of Changing Emissions and Climate
(2021-07-12)Certain anthropogenic organic pollutants persist in the environment, bioaccumulate and are toxic to humans and wildlife. They accumulate in the global oceans where marine biogeochemical cycles drive their fate and distribution. ... -
Implications of human-induced climate change on regional climate and potential mitigation solutions
(2022-01-14)Emissions of fossil fuels have invariably had important ramifications on global, but also regional climate. These impacts, by their nature, encompass a wide scope, and call for the study of both adaptation and mitigation. ... -
Microbial colonization and dissolution of mercury sulfide minerals
(2014-10-22)Mercury (Hg) is a toxic heavy metal that poses significant human and environmental health risks. Mineral-associated Hg is the largest reservoir of Hg in the environment where it can account for nearly 60% of the global Hg ... -
Modeling Aerosol Transport for Stratospheric Solar Geoengineering: from Particle to Plume Scale
(2023-05-12)Stratospheric Aerosol Injection (SAI) aims to offset some climate hazards by releasing aerosols into the stratosphere to reflect solar radiation. In this thesis, we outline the use of new modeling methods to simulate aerosol ... -
Modeling the environmental and public health impacts of smoke from biomass burning in the Amazon Basin
(2022-09-07)Deforestation rates and fires counts in the Amazon Basin have increased dramatically since the 1980s. Smoke emitted by the Amazon fires affects not just air quality in the surrounding areas but may also have an impact on ... -
Quantifying Methane Emissions Using Satellite Observations
(2014-02-25)Methane is the second most influential anthropogenic greenhouse gas. There are large uncertainties in the magnitudes and trends of methane emissions from different source types and source regions. Satellite observations ...
