Experience           Advisors: Mario Molina, Kimberly Prather, Fellowship Mentors: Paul Crutzen, Ulrich Platt

Constructed a Multi-Axes Differential Optical Absorption Spectroscopy (MAX-DOAS) instrument optimized for the remote sensing of glyoxal, and expanded my field work in areas of rapid economic growth in close coordination with satellite overpasses. Participated in field campaigns in Mexico City, Mexico (MILAGRO) and the Pearl River Delta, China (PRD-2006). Analysed MCMA-2003 data and demonstrated that secondary organic aerosol (SOA) formation from anthropogenic sources is much higher than expected, with implications for the global radiation balance. Box modelling based on the Master Chemical Mechanism (MCMv3.1) revealed shortcomings in our understanding of glyoxal sinks, and oxidative capacity in urban air. Currently starting a novel laboratory research program on SOA formation from glyoxal using Chemical Ionization mass spectrometry (CIMS), and aerosol mass spectrometry. Continued collaborations with Atmospheric Science and Global Change Division, PNNL to understand aerosol optical properties in the polluted atmosphere, and EMSL’s molecular spectroscopy facility to measure a high-resolution absorption cross-section of naphthalene.

Advisor: Mario Molina

Participated in the MCMA-2003 field campaign in Mexico City deploying two active open-path DOAS instruments (i.e. use of Xe-arc lamp), one open-path FTIR, and one spectroradiometer with the objective to (1) quantify the HOx-radical fluxes from primary radical sources, and (2) develop a cost effective approach to quantify representative emission factors of NOx and VOC emissions from mobile sources. The first direct detection of glyoxal in the atmosphere was accomplished. Glyoxal presents a novel marker molecule to better characterize photochemical hot-spots in the troposphere. Our work predicted feasibility to measure glyoxal using solar straylight techniques, and I established successful collaborations to detect glyoxal by ground-based MAX-DOAS at M.I.T. and onboard a NOAA research vessel (with UHeidelberg), and from two satellites (i.e. OMI onboard EOS-Aura, and SCIAMACHY on Envisat, with Harvard Smithsonian CfA, UBremen, and UHeidelberg).

 

University of Leeds                                                           Leeds, United Kingdom

On invitation by: Mike Pilling, Advisor: Ulrich Platt

As part of a research stay in the Chemical Dynamics group within the Chemistry Department, the representations of aromatic hydrocarbon oxidation schemes in the Master Chemical Mechanism (MCMv3.1) were updated and evaluated. This involved knowledge transfer of results obtained as part of my PhD.

 

University of Bremen                                                       Bremen, Germany

On invitation by: John Burrows, Advisor: Ulrich Platt

As part of a research stay in the Molecular Spectroscopy and Chemical Dynamics group within the Physics Department, a high-resolution absorption cross-section of glyoxal was recorded in the ultraviolet-visible (UV-vis) and infrared (IR) spectral ranges using the Fourier Transform Spectrometer (Bruker FTS120 HR). Ours is the recommended UV-vis spectrum by the NASA panel for Data evaluationChemical Kinetics and Photochemical Data for Use in Atmospheric Studies” (JPL Publication 06-2)

 

Ruprecht-Karls-University                                             Heidelberg, Germany

                Advisor: Ulrich Platt, Advisory Board: Paul Crutzen

Research focused on the chemical kinetics and the mechanism of anthropogenic and biogenic hydrocarbon oxidation in outdoor simulation chambers. Compilation of a database of validated UV- absorption cross-sections for use in the quality assurance of remote sensing data and instrument development for the DOAS technique. Participation in international field campaigns in the Po Valley, in the northern part of Italy, to intercompare four in-situ measurement techniques for formaldehyde (FORMAT-1), in Houston, TX (Southern Oxidant Study 2000 with Jochen Stutz of U.C. Los Angeles), and at Kleiner Feldberg, Germany (DBU). During my Diploma work, I set-up the White-DOAS system at EUPHORE, and studied the spectroscopy of molecular oxygen in the Herzberg bands, which superpose with the absorption features of aromatic hydrocarbons in the ultraviolet spectral range (between ca. 243nm and 287nm). The successful elimination of oxygen absorptions enables the sensitive DOAS measurement of aromatic hydrocarbons in the open atmosphere.

 


European Photo Reactor (EUPHORE)                           Valencia, Spain

                               Advisors: Klaus Wirtz, Millan Millan

Pioneered the use of DOAS in outdoor simulation chambers to study chemical kinetics and the oxidation mechanism of aromatic hydrocarbons. This included improving the DOAS White-system to avoid de-alignment of the mirror system during chamber operation, measurement of photolysis frequencies of aromatic aldehydes, OH- and NO3-radical rate constants of selected aromatic aldehydes and phenols. Product studies of the benzene, toluene and para-xylene reaction with OH-radicals at variable NOx levels revealed higher glyoxal yields; the phenol yield from the benzene + OH reaction was found twice as high as previously existing literature values had suggested. The atmospheric relevance of our results was demonstrated, and allowed to quantify the major reaction pathway from aromatic oxidation. Techniques employed included White-DOAS, White-FTIR, GC-FID, GC-ECD, filterradiometry (JNO2), NOx instrumentation, criteria pollutant gas-monitors.
