TL;DR: Results demonstrate that mineral dust and metallic particles are the dominant source of residual particles, whereas sulfate and organic particles are underrepresented, and elemental carbon and biological materials are essentially absent.

TL;DR: In this paper, the authors present a calibration of TCCON data using WMO-scale in-strumentation aboard aircraft that measured profiles over four Total Carbon Column Observing Network (TCCON) stations.

TL;DR: In this paper, the authors used aircraft observations of Asian outflow from the NASA Transport and Chemical Evolution over the Pacific (TRACE-P) mission over the NW Pacific in March-April 2001 to estimate the export efficiency of black carbon (BC) aerosol during lifting to the free troposphere, as limited by scavenging from the wet processes (warm conveyor belts and convection) associated with this lifting.

TL;DR: Vehicle NH3 emissions are greater than agricultural emissions in counties containing near half of the U.S. population and require reconsideration in urban air quality models due to their colocation with other aerosol precursors and the uncertainties regarding NH3 losses from upwind agricultural sources.

TL;DR: In this article, the future atmospheric burden of methane in the Arctic Ocean has been studied and uncertainty in the future burden of the greenhouse gas has been identified as an important challenge to the development of realistic climate projections.
