[HTML][HTML] Pyrogenic carbon erosion: implications for stock and persistence of pyrogenic carbon in soil

RB Abney, AA Berhe - Frontiers in Earth Science, 2018 - frontiersin.org
Pyrogenic carbon (PyC) constitutes an important pool of soil organic matter (SOM), particularly
for its reactivity and because of its assumed long residence times in soil. In the past, …

Pyrogenic carbon erosion after the Rim Fire, Yosemite National Park: The role of burn severity and slope

RB Abney, TJ Kuhn, A Chow… - Journal of …, 2019 - Wiley Online Library
Pyrogenic carbon (PyC) is an incomplete combustion by‐product with longer soil residence
times compared with nonpyrogenic components of the soil carbon (C) pool and can be …

Microbial mechanisms and ecosystem flux estimation for aerobic NOy emissions from deciduous forest soils

…, RP Phillips, ZC Payne, RB Abney… - Proceedings of the …, 2019 - National Acad Sciences
Reactive nitrogen oxides (NO y ; NO y = NO + NO 2 + HONO) decrease air quality and impact
radiative forcing, yet the factors responsible for their emission from nonpoint sources (ie, …

Burn intensity drives the alteration of phenolic lignin to (Poly) aromatic hydrocarbons as revealed by pyrolysis gas chromatography–mass spectrometry (Py-GC/MS)

…, JJ Wang, PJ Ku, MTK Tsui, RB Abney… - … science & technology, 2022 - ACS Publications
High-intensity wildfires alter the chemical composition of organic matter, which is expected
to be distinctly different from low-intensity prescribed fires. Herein, we used pyrolysis gas …

[HTML][HTML] Post-wildfire erosion in mountainous terrain leads to rapid and major redistribution of soil organic carbon

RB Abney, J Sanderman, D Johnson… - Frontiers in Earth …, 2017 - frontiersin.org
Catchments impacted by wildfire typically experience elevated rates of post-fire erosion and
formation and deposition of pyrogenic carbon (PyC). To better understand the role of …

Reaction of Organic Matter with Nitronium Ion as a Source of Organic Nitrate Esters in Proxies for Organic Aerosols

RF Hansen, EZ Dalton, RB Abney… - ACS Earth and Space …, 2023 - ACS Publications
Organic nitrate ester compounds (RONO 2 ) are an important sink for nitrogen oxides (NO x
≡ NO + NO 2 ) that impact ozone and organic aerosol formation in the lower atmosphere. …

The role of the physical properties of soil in determining biogeochemical responses to soil warming

F Santos, R Abney, M Barnes, N Bogie… - … consequences of soil …, 2019 - Elsevier
Warmer air temperatures projected for the coming centuries are expected to increase soil
temperature and accelerate the rate of biogeochemical processes. Currently, there is limited …
