We report Thermal Desorption Chemical Ionization Mass Spectrometer (TDCIMS) measurements of the composition ambient 10–33 nm diameter particles formed from nucleation on 16 March 2006 in Tecamac, Mexico during Megacity Initiative: Local and Global Research Observations (MILAGRO) field study. On this day, nucleated contained far more organics than sulfates: average ion molar ratios with measurement uncertainties for nitrate, sulfur species were 6 ± 2%, 84 5%, 10 1%, respectively. The measured...
Abstract A Large Eddy Simulation (LES) model capable of accurately representing finite-rate chemistry effects in turbulent premixed combustion is presented. The LES computations use and implicit modelling to simulate an experimentally well-documented lean-premixed jet flame stabilized by a stoichiometric pilot. validity the assumption discussed criteria are expressed terms subgrid scale Damköhler Karlovitz numbers. results compared experimental data for velocity, temperature species mass...
Continuous measurements of the size distribution atmospheric aerosol in 3–48 nm diameter range were performed Mexico City metropolitan area. These made during period 10–20 April 2003 at a ground‐based, mountain pass site southeast corner Federal District and 2–11 May CENICA located near city center. The objectives this work to determine frequency new particle formation characterize chemical meteorological conditions that lead these events. Several events recorded study. Events observed...
This paper investigates the role of ion‐induced nucleation (IIN) in new particle formation events observed near ground level at a sampling site located Boulder, Colorado (14 March 2004 to 27 October 2005). Measurements mobility distributions small and intermediate ions (0.4–6.3 nm), size total particles (3 nm 5 μ m), charged fractions (2.5–25 nm) were carried out. The relative contributions neutral IIN inferred using both qualitative quantitative analyses. First, simple theoretical analysis...
