Abstract Isoprene dominates global non-methane volatile organic compound emissions, and impacts tropospheric chemistry by influencing oxidants aerosols. emission rates vary over several orders of magnitude for different plants, characterizing this immense biological chemodiversity is a challenge estimating isoprene from tropical forests. Here we present the estimates aircraft eddy covariance measurements Amazonian forest. We report that are three times higher than satellite top-down 35%...
In coastal environments like the Chesapeake Bay, presence of sea/bay breeze circulation can contribute to poor air quality and makes modeling meteorological chemical impacts in forecast models a challenge. The Ozone Water-Land Environmental Transition Study 2 field campaign aimed better quantify mechanisms affecting surface, profile, columnar trace gas amounts between land water. Using HYSPLIT back trajectory modeling, variability Pandora NO2 surface O3 was quantified. Clustered trajectories...
Abstract. We present a new version of the Brazilian developments on Regional Atmospheric Modeling System where different previous versions for weather, chemistry and carbon cycle were unified in single integrated software system. The also has set state-of-the-art physical parameterizations greater computational parallel memory usage efficiency. Together with description main features are examples quality transport scheme scalars, radiative fluxes surface model simulation rainfall systems...
Abstract. We present a characterization of the chemical composition atmosphere Brazilian Amazon rainforest based on trace gas measurements carried out during South AMerican Biomass Burning Analysis (SAMBBA) airborne experiment in September 2012. analyzed observations primary biomass burning emission tracers, i.e., carbon monoxide (CO), nitrogen oxides (NOx), ozone (O3), isoprene, and its main oxidation products, methyl vinyl ketone (MVK), methacrolein (MACR), isoprene hydroxy hydroperoxide...
Abstract. Analysis of formaldehyde measurements by the Pandora spectrometer systems between 2016 and 2019 suggested that there was a temperature-dependent process inside head sensor emitted formaldehyde. Some parts in were manufactured from thermal plastic polyoxymethylene homopolymer (E.I. Du Pont de Nemour & Co., USA; POM-H Delrin®) responsible for production. Laboratory analysis four sensors showed internal production had exponential temperature dependence with damping coefficient...
