A Meteorological Overview of the Arctas 2008 Mission : Volume 9, I...

By: D. L. Harrigan; W. Sessions; H. E. Fuelberg

Description: Department of Meteorology, Florida State University, Tallahassee, FL, USA. The Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) mission was a multi-aircraft project whose major objective was to investigate the factors driving changes in the Arctic's atmospheric composition and climate. It was conducted during April and June–July 2008. The summer ARCTAS deployment was preceded by a week of flights over and aroun...

Description: Center for Weather Forecasting and Climate Studies, INPE, Cachoeira Paulista, Brazil. We describe and begin to evaluate a parameterization to include the vertical transport of hot gases and particles emitted from biomass burning in low resolution atmospheric-chemistry transport models. This sub-grid transport mechanism is simulated by embedding a 1-D cloud-resolving model with appropriate lower boundary conditions in each column of the 3-D host model. T...

The Isotopic Composition of Methane in the Stratosphere: High-alti...

By: M. Brass; A. Engel; R. Borchers; T. Röckmann

Description: Institute for Marine and Atmospheric Research Utrecht, Utrecht University, Utrecht, The Netherlands. The isotopic composition of stratospheric methane has been determined on a large suite of air samples from stratospheric balloon flights covering subtropical to polar latitudes and a time period of 16 yr. 154 samples were analyzed for δC and 119 samples for ΔD, increasing the previously published dataset for balloon borne samples by an order o...

Aqueous Phase Oligomerization of Methyl Vinyl Ketone Through Photo...

By: D. Voisin; L. Vassalo; B. Temime-roussel; G. Salque; A. Smaani; F. Siekmann; C. Demelas; S. Ravier; P. Renard; A. Monod; B. Coulomb

Description: Aix-Marseille Université, CNRS, LCE FRE 3416, 13331, Marseille, France. Secondary organic aerosol (SOA) represents a substantial part of organic aerosol, which affects climate and human health. It is now accepted that one of the important pathways of SOA formation occurs via aqueous phase chemistry in the atmosphere. Recently, we have shown in a previous study (Renard et al., 2013) the mechanism of oligomerization of MVK (methyl vinyl ketone), and ...

Instantaneous Longwave Radiative Impact of Ozone: an Application ...

By: K. W. Bowman; L. Clarisse; D. Hurtmans; C. Clerbaux; S. Doniki; H. M. Worden; P.-f. Coheur

Description: Spectroscopie de l'Atmosphère, Service de Chimie Quantique et Photophysique, Université Libre de Bruxelles (ULB), Brussels, Belgium. Ozone is an important greenhouse gas in terms of anthropogenic radiative forcing (RF). RF calculations for ozone were until recently entirely model based and significant discrepancies were reported due to different model characteristics. However, new instantaneous radiative kernels (IRKs) calculated from hyperspectral ...
