Journal ArticleDOI
Tropospheric Aerosol Optical Thickness from the GOCART Model and Comparisons with Satellite and Sun Photometer Measurements
Mian Chin,Paul Ginoux,Stefan Kinne,Stefan Kinne,Omar Torres,Omar Torres,Brent N. Holben,Bryan N. Duncan,Randall V. Martin,Jennifer A. Logan,Akiko Higurashi,Teruyuki Nakajima +11 more
TL;DR: The Georgia Institute of Technology's Goddardard Global Ozone Chemistry Aerosol Radiation and Transport (GOCART) model is used to simulate the aerosol optical thickness t for major types of tropospheric aerosols including sulfate, dust, organic carbon (OC), black carbon (BC), and sea salt.
Journal ArticleDOI
Interannual and seasonal variability of biomass burning emissions constrained by satellite observations
Bryan N. Duncan,Bryan N. Duncan,Randall V. Martin,A. C. Staudt,A. C. Staudt,Rosemarie Yevich,Jennifer A. Logan +6 more
TL;DR: In this paper, the authors present a methodology for estimating the seasonal and interannual variation of biomass burning designed for use in global chemical transport models, using the Total Ozone Mapping Spectrometer (TOMS) Aerosol Index (AI) data set.
Journal ArticleDOI

TL;DR: The Ozone Monitoring Instrument (OMI) onboard NASA's Aura satellite has been providing global observations of the ozone layer and key atmospheric pollutant gases, such as nitrogen dioxide (NO2) and sulfur dioxide (SO2), since October 2004 as mentioned in this paper.

TL;DR: In this article, an ensemble of 21 global and hemispheric chemical transport models is used to estimate the spatial average surface ozone (O-3) response over east Asia (EA), Europe (EU), North America (NA), and south Asia (SA) to 20% decreases in anthropogenic emissions of the O-3 precursors, NOx, NMVOC, and CO.
