Marcellus Shale research presented at American Geophysical Union Conference


Ph.D. student Doug Goetz presents his work on Site Specific Emission Characterization of Marcellus Shale Development using Fast Mobile Measurements at the 2013 Fall AGU meeting in San Francisco.  Doug has put substantial work and time into calculating emission factors and source profiles from our collaborative study with Aerodyne Research Inc and the Electric Power Research Institute.  Stay tuned for upcoming publications on the study.

Presentations by DeCarlo Group at AAAR 2013

Second year graduate student, Anita Johnson, presented her research on the characterization of the mini-AMS at the 2013 AAAR annual conference in Portland Oregon.

Ss 117

The mini-AMS has also been used to characterize the transport of outdoor particles to the indoor environment. The project is a collaboration with Dr. Waring who studies indoor air quality with interest in indoor SOA formation. This study represents one of the first uses of an AMS to study aerosol size and composition in the indoor environment.  We are looking forward to the final product of this exciting work.

SP-AMS has arrived!


SP-AMS Training at Drexel


The SP-AMS, acquired from an NSF MRI (Award: 1229298), has arrived at Drexel.  Ed Fortner from Aerodyne is pictured here instructing Drexel Graduate students on calibration procedures and general use principles of the SP-AMS.  We’re very excited to add this new instrument to the DeCarlo laboratory at Drexel, and get to work on new projects.

CLEAR PM makes its debut

CLEAR PM on Tour

As part of the Franklin Institute’s Climate Urban Systems Partnership, we were invited to take our Particle measurement and display system to the Lutheran Settlement House in the New Kensington neighborhood of Philadelphia.  The maiden voyage of the particle display system was not without it’s bugs, but overall the students enjoyed the display.  Especially the “fire”.

CLEAR PM: Dreyfus Foundation Award

The Camille and Henry Dreyfus Foundation has awarded Drs DeCarlo and Waring a grant to develop a tool to teach students and the public about the chemistry of Aerosols. CLEAR PM: Chemistry Lessons Enabling Aerosol Realizations with Particulate Measurements will combine several instruments capable of rapid measurements with a real-time display, and modules for demonstrating chemistry and aerosol concepts. Dr. DeCarlo will incorporate the development and construction of this module into a course he is teaching in the spring quarter. Stay tuned for updates.

Marcellus Air Quality Research

A team of researchers from Drexel University and Aerodyne Research joined forces in the Marcellus Shale Region of Pennsylvania. The goals of the EPRI sponsored study were to both characterize the regional background atmospheric composition in the Marcellus Region, and to make measurements of air emissions related to natural gas extraction and distribution activities. Two weeks of intense mobile and fixed site measurements were performed in the NE and SW parts of Pennsylvania. We are excited about the measurements, and looking forward to digging through the massive amount of data generated.

One of the most rewarding parts of any study like this is to know that your work is appreciated. Thank you Lily and Elisabeth. The cookies were delicious.

Marcellus Shale Field Trip written up in EXEL magazine


Drexel University’s research magazine XCEL, published an article on the Marcellus Shale Research at Drexel University.  Photos in the article come from a field trip taken by faculty and students from Drexel’s Civil, Architectural, and Environmental Engineering Department as well as program managers from the Electric Power Research Institute.  Cabot Oil and Gas and Energy in Depth were gracious hosts of the Drexel contingent, and gave us guided tours of producing wells, water treatment facilities, drill sites, and a site where hydraulic fracturing was occurring.  It was a long but exciting day, and gave us the opportunity to learn a lot about the process of hydraulic fracturing.  The issues related to natural gas extraction in the Marcellus region will continue to be one of importance for years to come, and it is important to understand all aspects of the process.   More field trip photos can be found here.

Coming soon: SP-AMS and other aerosol measurement tools

The National Science Foundation recently funded our proposal to acquire an Aerodyne Soot-Particle Aerosol Mass Spectrometer (SP-AMS) (Award ID: 1229298).  The acquisition of the SP-AMS will create opportunities for cutting edge aerosol research not only in Philadelphia, but also in the greater mid-Atlantic region and beyond.  We are eagerly awaiting the arrival of the SP-AMS, and are looking forward to the science we can achieve with the cutting-edge analytical instrumentation.  Thank you NSF, and stay tuned!
