Rivier,Yousuke Sawa,Martina Schmidt,L. P. Steele,Stephanie A. Vay,Alex Vermeulen,S. C. Wofsy,Douglas E. J. Worthy +31 more
TL;DR: In this article, a global Bayesian variational inversion of CO2 surface fluxes during the period 1988-2008 is presented, where weekly fluxes are estimated on a 3.75 degrees x 2.5 degrees (longitude-latitude) grid throughout the 21 years.
Journal ArticleDOI
Distribution and fate of selected oxygenated organic species in the troposphere and lower stratosphere over the Atlantic
Hanwant B. Singh,Y. Chen,Azadeh Tabazadeh,Yasuo Fukui,Isabelle Bey,Robert M. Yantosca,Daniel J. Jacob,Frank Arnold,K. H. Wohlfrom,Elliot Atlas,Frank Flocke,Donald R. Blake,Nicola J. Blake,Brian G. Heikes,J. Snow,Robert W. Talbot,Gerald L. Gregory,G. W. Sachse,Stephanie A. Vay,Yasuyuki Kondo +19 more
TL;DR: In this paper, the authors present a first picture of the distribution of these oxygenated organic chemicals (Ox-organic) in the troposphere and the lower stratosphere, and assess their source and sink relationships.
Journal ArticleDOI
Coherent differential absorption lidar measurements of CO2.
Grady J. Koch,Bruce W. Barnes,M. Petros,Jeffrey Y. Beyon,Farzin Amzajerdian,Jirong Yu,Richard E. Davis,Syed Ismail,Stephanie A. Vay,M. J. Kavaya,U. N. Singh +10 more
TL;DR: A differential absorption lidar has been built to measure CO2 concentration in the atmosphere, using a pulsed single-frequency Ho:Tm:YLF laser at a 2.05-microm wavelength and a coherent heterodyne receiver to achieve sensitive detection.
Journal ArticleDOI
Carbon dioxide column abundances at the Wisconsin Tall Tower site
Rebecca A. Washenfelder,Rebecca A. Washenfelder,Geoffrey C. Toon,J.-F. Blavier,Z. Yang,Norton Allen,Paul O. Wennberg,Stephanie A. Vay,D. M. Matross,Bruce C. Daube +9 more
TL;DR: In this article, an automated observatory for measuring atmospheric column abundances of CO_2 and O_2 using near-infrared spectra of the Sun obtained with a high spectral resolution Fourier Transform Spectrometer (FTS) was developed.
Journal ArticleDOI
Asian Outflow and Trans-Pacific Transport of Carbon Monoxide and Ozone Pollution: An Integrated Satellite, Aircraft, and Model Perspective
Colette L. Heald,Daniel J. Jacob,Arlene M. Fiore,Louisa K. Emmons,John C. Gille,Merritt N. Deeter,Juying Warner,David P. Edwards,James H. Crawford,A. J. Hamlin,A. J. Hamlin,Glen W. Sachse,Edward V. Browell,Melody A. Avery,Stephanie A. Vay,David J. Westberg,Donald R. Blake,Hanwant B. Singh,Scott T. Sandholm,Robert W. Talbot,Henry E. Fuelberg +20 more
TL;DR: In this paper, the authors combine satellite observations of carbon monoxide (CO) from the Measurements of Pollution in the Troposphere (MOPITT) instrument with measurements from the Transport and Chemical Evolution Over the Pacific (TRACE-P) aircraft mission over the northwest Pacific and with a global three-dimensional chemical transport model (GEOS-CHEM) to quantify Asian pollution outflow and its trans-Pacific transport during spring 2001.
