Chapter 1. Background: Asthma is the most common chronic childhood disease and is characterized by recurrent airway obstruction, bronchial hyper-responsiveness, and airway inflammation. Asthma is the leading cause of childhood hospitalization and school absenteeism in the United States.

Lamont Ph. student Xiaomeng Jin defends her thesis next month. Photo courtesy of Xiaomeng Jin. Next month, when Lamont Ph. student Xiaomeng Jin defends her thesis, she will have a significant body of work to reference, dissertation ozone. Along the way, she has found new ways to track and interpret ozone formation.
She focused on engineering in her undergraduate program, where her senior thesis led to two journal articles in Remote Sensing and International Journal of Climatology. Jin says the rigor of this program prepared her well for her research life at Lamont. During her time at the observatory, Jin has drawn high honors. She received the American Geophysical Union Outstanding Student Presentation Award in Fall and Fall She has received the NASA Earth and Dissertation ozone Science Fellowship and made significant strides in the understanding of the chemistry driving ozone formation, which in turn has yielded important information for air quality control efforts.
Most recently, her work included a unique approach to investigating satellite images and linking that data to ground-level ozone. This latest dissertation ozone was motivated by pervasive summertime ozone pollution across the U.
Ground-level ozone is created by chemical reactions between oxides of nitrogen NOx and volatile organic compounds VOC in the presence of sunlight, dissertation ozone. Environmental health researchers have found that exposure to ozone in these summertime concentrations can trigger coughing, throat irritation, and make existing ailments such as bronchitis, emphysema, dissertation ozone, and asthma worse. Ground-level ozone may also reduce lung function and inflame the linings of the lungs.
In earlier research, Jin used satellite measurements of the two different precursor gases that contribute to ozone formation NOx and VOCsand by using dissertation ozone as tracers, was able to track changes dissertation ozone this chemistry over the past decade. In this way, she was dissertation ozone to look at the impact of emission controls on surface ozone, dissertation ozone.
In the latest study, dissertation ozone, Jin has extended the record of air analysis to two decades by using multiple satellites, and—for the first time—connected this data directly to ozone observations on the ground.
By doing so, she has found a way to confirm that the satellite data is telling us important information about ozone in surface air where humans breathe, dissertation ozone. The satellite data shows the effectiveness of air pollution controls that were enacted between and The study caps a dissertation ozone of productive research. She has a real knack for combining different kinds of datasets in new ways. She was awarded the NOAA Climate and Global Change Postdoctoral Fellowshipdissertation ozone, which will support her study of the impacts of wildfires on atmospheric composition.
For Jin, the conclusion of her studies at Lamont has a bittersweet aspect. The coronavirus pandemic is making it more difficult to say goodbye, dissertation ozone. from Columbia.

Ozone causes an estimated deaths from all causes, more than hospital admissions and more than 4, emergency department visits among children and adults. Reducing ozone levels by 10% could prevent more than 80 premature deaths, hospital admissions and emer-gency department visits annually (Table 2) When hiring candidates for the Dissertation Ozone writer’s position, we apply a very rigid shortlisting procedure, helping us to ensure Dissertation Ozone that only professional and motivated specialists enter the Write My Essay Online family.
