Accelerated Reduction in \(SO_2\) Emissions from the U.S. Power Sector Triggered by Changing Prices of Natural Gas
Lu, Xi; McElroy, Michael Brendon; Wu, Gang; Nielsen, Chris (American Chemical Society, 2012)Emissions of sulfur dioxide (\(SO_2\)) from the U.S. power sector decreased by 24% in 2009 relative to 2008. The Logarithmic Mean Divisia Index (LMDI) approach was applied to isolate the factors responsible for this decrease. ... -

Wang, Yuxuan X.; McElroy, Michael Brendon (Wiley-Blackwell, 2004)Observations of CO and NOy from the Transport and Chemical Evolution over the Pacific (TRACE-P) aircraft mission over the northwest Pacific and from two Chinese ground stations (Hong Kong and Lin An) during spring 2001 are ... -
Atmospheric distribution of 85 Kr simulated with a general circulation model
Jacob, Daniel James; Prather, Michael J.; Wofsy, Steven Charles; McElroy, Michael Brendon (Wiley-Blackwell, 1987)A three-dimensional chemical tracer model for the troposphere is used to simulate the global distribution of 85Kr, a long-lived radioisotope released at northern mid-latitudes by nuclear industry. Simulated distributions ... -
Challenges faced by China compared with the US in developing wind power
Lu, Xi; McElroy, Michael Brendon; Peng, Wei; Liu, Shiyang; Nielsen, Chris; Wang, Haikun (Springer Nature, 2016)In the 21st Conference of the Parties held in Paris in December 2015, China pledged to peak its carbon emissions and increase non-fossil energy to 20% by 2030 or earlier. Expanding renewable capacity, especially wind power, ... -
China's CO2 emissions estimated from the bottom up: Recent trends, spatial distributions, and quantification of uncertainties
Zhao, Yu; Nielsen, Chris; McElroy, Michael Brendon (Elsevier BV, 2012)China’s emissions of anthropogenic CO2 are estimated using a bottom-up emission inventory framework based on a detailed categorization of economic sectors and provincial economic and energy data. It includes a newly compiled ... -
China’s CO2 Peak Before 2030 Implied From Characteristics and Growth of Cities
Lu, Xi; Deng, Yu; Sun, Yaoguang; Liu, Yifan; Zhu, Ge; Bu, Maoliang; Bi, Jun; McElroy, Michael; Wang, Haikun; Nielsen, Chris (Springer Science and Business Media LLC, 2019-07-29)China pledges to peak CO2 emissions by 2030 or sooner under the Paris Agreement to limit global warming to 2 °C or less by the end of the century. By examining CO2 emissions from 50 Chinese cities over the period 2000–2016, ... -
A Climate-friendly Energy Future: Prospects for Wind
Huang, Junling (2014-06-06)The objective of this thesis is to evaluate the potential for wind as an alternative energy source to replace fossil fuels and reduce global CO2 emissions. From 1995 to 2007, fossil fuels as the major energy source accounted ... -
CO emissions in China: Uncertainties and implications of improved energy efficiency and emission control
Zhao, Yu; Nielsen, Chris; McElroy, Michael Brendon; Zhang, Lin; Zhang, Jie (Elsevier BV, 2012)A bottom-up methodology and an improved database of emission factors combining the latest domestic field measurements are developed to estimate the emissions of anthropogenic CO from China at national and provincial levels. ... -
CO2 and its correlation with CO at a rural site near Beijing: implications for combustion efficiency in China
Wang, Y.; Munger, J. W.; Xu, S.; McElroy, Michael Brendon; Hao, J.; Nielsen, Chris; Ma, H. (Copernicus GmbH, 2010)Although China has surpassed the United States as the world's largest carbon dioxide emitter, in situ measurements of atmospheric CO2 have been sparse in China. This paper analyzes hourly CO2 and its correlation with CO ... -
Constraint of anthropogenic NOx emissions in China from different sectors: a new methodology using multiple satellite retrievals
Lin, J.-T.; McElroy, Michael Brendon; Boersma, K. F. (Copernicus GmbH, 2010)A new methodology is developed to constrain Chinese anthropogenic emissions of nitrogen oxides (NOx) from four major sectors (industry, power plants, mobile and residential) in July 2008. It combines tropospheric NO2 column ... -
The Contemporary and Historical Budget of Atmospheric \(CO_2\)
Huang, Junling; McElroy, Michael Brendon (NRC Research Press, 2012)Observations of \(CO_2\) and \(O_2\) are interpreted to develop an understanding of the changes in the abundance of atmospheric \(CO_2\) that have arisen over the period 1995–2007. Fossil fuels accounted for an addition ... -
Contributions of the Hadley and Ferrel Circulations to the Energetics of the Atmosphere over the past 32-years
Huang, Junling; McElroy, Michael Brendon (American Meteorological Society, 2014)The Hadley system provides an example of a thermally direct circulation, the Ferrel system in contrast an example of a thermally indirect circulation. In this study, we develop an approach to investigate the key thermodynamic ... -
Costs for Integrating Wind into the Future ERCOT System with Related Costs for Savings in \(CO_2\) Emissions
Lu, Xi; McElroy, Michael Brendon; Sluzas, Nora A. (American Chemical Society, 2011)Wind power can make an important contribution to the goal of reducing emissions of \(CO_2\).

Detection from space of a reduction in anthropogenic emissions of nitrogen oxides during the Chinese economic downturn
Lin, J.-T.; McElroy, Michael Brendon (Copernicus GmbH, 2011)Rapid economic and industrial development in China and relatively weak emission controls have resulted in significant increases in emissions of nitrogen oxides (NOx) in recent years, with the exception of late 2008 to mid ... -
