Synthesis of Satellite (MODIS), Aircraft (ICARTT), and Surface (IMPROVE, EPA-AQS, AERONET) Aerosol Observations over Eastern North America to Improve MODIS Aerosol Retrievals and Constrain Surface Aerosol Concentrations and Sources

Drury, Easan; Jacob, Daniel James; Spurr, Robert J. D.; Wang, Jun; Shinozuka, Yohei; Anderson, Bruce E.; Clarke, Antony D.; Dibb, Jack; McNaughton, Cameron; Weber, Rodney (Wiley-Blackwell, 2010)

We use an ensemble of satellite (MODIS), aircraft, and ground-based aerosol observations during the ICARTT field campaign over eastern North America in summer 2004 to (1) examine the consistency between different aerosol ...

Regional Visibility Statistics in the United States: Natural and Transboundary Pollution Influences, and Implications for the Regional Haze Rule

Park, Rojkin J.; Jacob, Daniel J.; Kumar, Naresh; Yantosca, Robert M. (Elsevier, 2006)

The Regional Haze Rule of the US Environmental Protection Agency mandates reduction in US anthropogenic emissions to achieve linear improvement of visibility in wilderness areas over the 2004–18 period toward an endpoint ...

Fire and Biofuel Contributions to Annual Mean Aerosol Mass Concentrations in the United States

Park, Rokjin J.; Jacob, Daniel J.; Logan, Jennifer A. (Elsevier, 2007)

We estimate the contributions from biomass burning (summer wildfires, other fires, residential biofuel, and industrial biofuel) to seasonal and annual aerosol concentrations in the United States. Our approach is to use ...

Climate forcings in Goddard Institute for Space Studies SI2000 simulations

Hansen, J.; Sato, M; Nazarenko, L; Ruedy, R; Lacis, A; Koch, D; Tegen, I; Hall, T; Shindell, D; Santer, B; Stone, P; Novakov, T; Thomason, L; Wang, R; Wang, Y; Jacob, Daniel James; Hollandsworth, S; Bishop, L; Logan, Jennifer A.; Thompson, A; Stolarski, R; Lean, J; Willson, R; Levitus, S; Antonov, J; Rayner, N; Parkerm, D; Christy, J (Wiley-Blackwell, 2002)

We define the radiative forcings used in climate simulations with the SI2000 version of the Goddard Institute for Space Studies (GISS) global climate model. These include temporal variations of well-mixed greenhouse gases, ...

Global and regional decreases in tropospheric oxidants from photochemical effects of aerosols

Martin, Randall V.; Jacob, Daniel James; Yantosca, Robert M.; Chin, Mian; Ginoux, Paul (Wiley-Blackwell, 2003)

We evaluate the sensitivity of tropospheric OH, O3, and O3 precursors to photochemical effects of aerosols not usually included in global models: (1) aerosol scattering and absorption of ultraviolet radiation and (2) ...

Natural and transboundary pollution influences on sulfate-nitrate-ammonium aerosols in the United States: Implications for policy

Park, Rokjin J.; Jacob, Daniel James; Field, Brendan; Yantosca, Robert M.; Chin, Mian (Wiley-Blackwell, 2004)

We use a global three-dimensional coupled oxidant-aerosol model (GEOS-CHEM) to estimate natural and transboundary pollution influences on sulfate-nitrate-ammonium aerosol concentrations in the United States. This work is ...

Interactions between tropospheric chemistry and aerosols in a unified general circulation model

Liao, Hong; Adams, Peter; Chung, Serena; Seinfeld, John; Mickley, Loretta J.; Jacob, Daniel James (Wiley-Blackwell, 2003)

A unified tropospheric chemistry-aerosol model has been developed within the Goddard Institute for Space Studies general circulation model (GCM). The model includes a detailed simulation of tropospheric ozone-NOx-hydrocarbon ...
