Applicability of a Portable Particle Monitor for Measuring TSP and PM10 in the Ambient Environment (2017-05-05)The National Ambient Air Quality Standard (NAAQS) was established and revised to regulate PM10 (particles less than or equal to 10 μm in aerodynamic diameter), as these small particles were found to penetrate and deposit ...
-
(2019-11-12)Ice nucleating particles (INP) are aerosol particles that catalyze the freezing of atmospheric water at temperatures warmer than homogeneous freezing, which occurs at -36 °C. INP contained in marine sea spray aerosols may ...

Atmospheric Measurements of Submicron Aerosols at the California-Mexico Border and in Houston, Texas (2013-04-29)Using an innovative arrangement of instruments to obtain a comprehensive set of properties, we present a description of the submicron aerosol properties for two distinct regions. During the 2009 SHARP/SOOT campaign in ...

(Texas A&M University. Libraries, 1992)Spray pyrolysis for ceramic powder preparation was studied, theoretically and experimentally. The forming mechanism for derived particles using air or argon as carrier was established based on the experimental results ...
-
(Texas A&M University. Libraries, 1986)A laser Doppler velocimeter was used to measure three components of velocity in the body of an 88.9 mm diameter, multiport, reverse flow sampling cyclone with a flat bottom. This velocity data was then nondimensionalized ...

The continuum regime charging of submicrometer particles by bipolar air ions : theory and experiment (Texas A&M University. Libraries, 1982)A study was undertaken to characterize experimentally the continuum regime charging of aerosols by bipolar gaseous ions and to evaluate theoretical models for the charging process. Experiments were conducted on monodisperse ...
-
(Texas A&M University. Libraries, 1979)Accurate estimation of effective dose received by an animal exposed to a given aerosol requires knowledge of the selective properties of the animal's respiratory system for trapping and retaining aerosol droplets of different ...
-
(2018-03-29)Atmospheric aerosols profoundly impact human health, visibility, the ecosystem, and the climate. Some aerosols are directly emitted, but a majority are formed in the atmosphere by the oxidation of gaseous precursors. ...
-
(2019-11-26)This dissertation investigated the impacts of natural and anthropogenic aerosols on Atlantic tropical cyclones by combining observational analyses and numerical modeling. The objectives of the research were to assess the ...
-
(Texas A&M University, 2007-09-17)A field-deployable instrument has been developed that isolates from an ambient aerosol population only those particles that have critical supersaturations, Sc, within a narrow, user-specified, range. This Differential ...
-
(2015-12-08)Atmospheric aerosols are a key contributor to pollution, adversely affect human health, and can alter global climate. Several questions concerning atmospheric aerosols persist, including: ‘Which atmospheric species are ...
-
(2018-05-05)In this study, the regional-scale aerosol effects are quantitatively assessed under various weather conditions by conducting numerical modeling studies to improve the understanding of physical processes involved in ...
-
(2017-12-22)Using a suite of coupled and uncoupled climate model experiments, we explore the impacts of anthropogenic sulfate aerosols on tropical Pacific climate and its variability. The role of sea surface temperature (SST), ocean ...
