• A 32-year Perspective on the Origin of Wind Energy in a warming Climate ﻿

(2015-02-04)
• Accelerated Reduction in $SO_2$ Emissions from the U.S. Power Sector Triggered by Changing Prices of Natural Gas ﻿

(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. ...
• Asian emissions of CO and NOx: Constraints from aircraft and Chinese station data ﻿

(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 ...
• Challenges faced by China compared with the US in developing wind power ﻿

(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 ﻿

(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 ...
• CO emissions in China: Uncertainties and implications of improved energy efficiency and emission control ﻿

(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 ﻿

(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 ﻿

(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 $CO_2$ ﻿

(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 ﻿

(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 ﻿

(American Chemical Society, 2011)
Wind power can make an important contribution to the goal of reducing emissions of $CO_2$. The major problem relates to the intrinsic variability of the source and the difficulty of reconciling the supply of electricity ...
• Detection from space of a reduction in anthropogenic emissions of nitrogen oxides during the Chinese economic downturn ﻿

(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 ...
• Emission trends and mitigation options for air pollutants in East Asia ﻿

(Copernicus GmbH, 2014)
Emissions of air pollutants in East Asia play an important role in the regional and global atmospheric environment. In this study we evaluated the recent emission trends of sulfur dioxide (SO<sub>2</sub>), nitrogen oxides ...
• Global Potential for Wind-Generated Electricity ﻿

The potential of wind power as a global source of electricity is assessed by using winds derived through assimilation of data from a variety of meteorological sources. The analysis indicates that a network of land-based ...
• Human and animal wastes: Implications for atmospheric N2O and NOx ﻿

(Wiley-Blackwell, 2005)
More than 220 Tg N are processed annually through the global agriculture/animal/human food chain. It is suggested that aerobic denitrification, reduction of nitrite formed in the first stage of nitrification, is an important ...
• The impact of Production Tax Credits on the profitable production of electricity from wind in the U.S. ﻿

(Elsevier BV, 2011)
A spatial financial model using wind data derived from assimilated meteorological condition was developed to investigate the profitability and competitiveness of onshore wind power in the contiguous U.S. It considers not ...
• Implications of the Recent Reductions in Natural Gas Prices for Emissions of $CO_2$ from the US Power Sector ﻿

(American Chemical Society, 2012)
$CO_2$ emissions from the US power sector decreased by 8.76% in 2009 relative to 2008 contributing to a decrease over this period of 6.59% in overall US emissions of greenhouse gases. An econometric model, tuned to data ...
• Meteorologically Defined Limits to Reduction in the Variability of Outputs from a Coupled Wind Farm System in the Central US ﻿

(Elsevier, 2013-08-26)
Studies suggest that onshore wind resources in the contiguous US could readily accommodate present and anticipated future US demand for electricity. The problem with the output from a single wind farm located in any ...
• Multiple effects and uncertainties of emission control policies in China: Implications for public health, soil acidification, and global temperature ﻿

(Elsevier BV, 2011)
Policies to control emissions of criteria pollutants in China may have conflicting impacts on public health, soil acidification, and climate. Two scenarios for 2020, a base case without anticipated control measures and a ...
