Autor: O. E. Salmon, L. R. Welp, M. E. Baldwin, K. D. Hajny, B. H. Stirm, P. B. Shepson

Publikováno v: Atmospheric Chemistry and Physics, Vol 19, Pp 11525-11543 (2019)

We use airborne measurements of water vapor (H2Ov) stable isotopologues and complementary meteorological observations to examine how boundary layer (BL) dynamics, cloud processing, and atmospheric mixing influence the vertical structure of δD, δ18O

Quantification and source apportionment of the methane emission flux from the city of Indianapolis

Publikováno v: Elementa: Science of the Anthropocene (2015)

Abstract We report the CH4 emission flux from the city of Indianapolis, IN, the site of the Indianapolis Flux Experiment (INFLUX) project for developing, assessing, and improving top-down and bottom-up approaches for quantifying urban greenhouse gas

Fluxes of Atmospheric Greenhouse-Gases in Maryland (FLAGG-MD): Emissions of Carbon Dioxide in the Baltimore, MD-Washington, D.C. area

Autor: D Y, Ahn, J R, Hansford, S T, Howe, X R, Ren, R J, Salawitch, N, Zeng, M D, Cohen, B, Stunder, O E, Salmon, P B, Shepson, K R, Gurney, T, Oda, I, Lopez-Coto, J, Whetstone, R R, Dickerson

Publikováno v: J Geophys Res Atmos

To study emissions of CO(2) in the Baltimore, MD-Washington, D.C. (Balt-Wash) area, an aircraft campaign was conducted in February 2015, as part of the FLAGG-MD (Fluxes of Atmospheric Greenhouse-Gases in Maryland) project. During the campaign, elevat
