The latest research from the labs of Penn scientists Paulo Arratia and Douglas Jerolmack was an answer to “a call for help,” says Arratia.
The aerodynamic size distributions of radon decay product aerosols, i.e. 214Pb, 212Pb, and 210Pb were measured using low-pressure (LPI) as well as conventional low-volume 1-ACFM and high-volume (HVI)...
Elemental and organic carbon (EC and OC), the principal short-lived climate forcers, were measured in fine particulate matter (PM2.5) collected at urban and rural sites in continental edge in Souther...
Size-segregated aerosol samples were collected continuously from July 2009 to June 2010 at urban area of Raipur, the eastern central India. The collected samples were analyzed for PM10 mass and its w...
Two ways of aerosols spreading analysis in atmosphere are presented. The first one is based on the one-level barotropic models. This case includes the simple tests of the numerical simulations spreadi...
A methodology has been developed for modeling and mapping various aerosol parameters using the IRS-P4 Ocean Color Monitoring [OCM] multi-spectral data having wide swath of 1420 km and high (360 m) sp...
Inactivation of collected viral aerosols is important for preventing a filter medium’s serving as a fomite. The focus of this study was to evaluate the inactivation efficiency (IE) achieved through f...
Meteorological and aerosol data were measured at the atmospheric boundary layer observation station in Tianjin, China, and were analyzed to study the effects of aerosol mass, composition, and size di...
Organic and elemental carbon (OC and EC) were measured in PM2.5 and PM10 at urban and suburban sites in Tianjin, China, from September 2009 to February 2010. Average PM2.5 and PM10 mass levels were 1...
Continuous measurements of black carbon (BC) mass concentration performed at Anantapur [14.62°N, 77.65°E, 331 m asl], a suburban location in southeast India, using an Aethalometer from January to Dec...
Lidar instruments have proven useful for characterizing the structure and dynamics of aerosol layers. We compare here the diurnal, seasonal and vertical variability of urban aerosols as described by ...
This paper reports the atmospheric concentrations of PM2.5 and PM1 mass, water soluble inorganic components and their seasonal variations measured between the period of July 2009 and June 2010 in Dur...
The sensitivity of aerosol radiative properties (i.e., scattering coefficient, extinction coefficient, single scatter albedo, and asymmetry factor) and radiation transmission to aerosol composition, s...
For the generation of the quasi-monodispersed standard (calibration) aerosols, the electrical separation of particles from the aerosol with wide size spectrum can be used in quite a wide particle dia...
Aerial observation was conducted during spring (March–April) 2008 over the East China Sea to analyze the transport of atmospheric pollutants from East Asia and the transformation processes during tra...
