Assessment of fossil fuel carbon dioxide and other anthropogenic trace gas emissions from airborne measurements over Sacramento, California in spring 2009
fossil fuel carbon dioxide anthropogenic trace gas airborne measurements Sacramento California
2011/2/24
Direct quantification of fossil fuel CO2 (CO2ff) in atmospheric samples can be used to examine several carbon cycle and air quality questions. We collected in situ CO2, CO, and CH4 measurements and fl...

We interpret observations from the Intercontinental Chemical Transport Experiment, Phase B (INTEX-B) in spring 2006 using a global chemical transport model (GEOS-Chem) to evaluate sensitivities of the...
Chemistry of hydrogen oxide radicals (HOx) in the Arctic troposphere in spring
hydrogen oxide radicals the Arctic troposphere spring
2010/8/13
We use observations from the April 2008 NASA ARCTAS aircraft campaign to the North American Arctic, interpreted with a global 3-D chemical transport model (GEOS-Chem), to better understand the sources...
Airborne measurements of aerosol optical properties related to early spring transport of mid-latitude sources into the Arctic
Airborne measurements aerosol optical properties mid-latitude sources the Arctic
2010/8/13
Airborne lidar and in-situ measurements of the aerosol properties were conducted between Svalbard Island and Scandinavia in April 2008. Evidence of aerosol transport from Europe and Asia is given. The...

Dust Chemical element composition Asian dust event
2016/3/29
The chemical element composition of dust particles was characterized by the ground-based samples collected at Beijing
in the spring of 2004. Most of mineral and pollutant element concentrations in pa...
Source attribution and interannual variability of Arctic pollution in spring constrained by aircraft (ARCTAS, ARCPAC) and satellite (AIRS) observations of carbon monoxide
Arctic pollution spring constrained ARCTAS carbon monoxide
2010/2/21
We use aircraft observations of carbon monoxide (CO) from the NASA ARCTAS and NOAA ARCPAC campaigns in April 2008 together with multiyear (2003–2008) CO satellite data from the AIRS instrument and a g...
Properties of aerosols and their wet deposition in the arctic spring during ASTAR2004 at Ny-Alesund, Svalbard

During the period of scientific campaign "Arctic Study of Tropospheric Aerosols, Clouds and Radiation 2004" (ASTAR2004), precipitation samples were collected in late spring at Ny-Alesund, Svalbard and...
The influence of polar vortex ozone depletion on NH mid-latitude ozone trends in spring
polar vortex ozone depletion NH mid-latitude ozone spring
2009/1/13
Reverse domain-filling trajectory calculations have been performed for the years 1993, 1995, 1996, 1997, and 2000 to calculate the spreading of ozone depleted air from the polar vortex to midlatitudes...
Regional aerosol optical properties and radiative impact of the extreme smoke event in the European Arctic in spring 2006
Regional aerosol optical properties radiative impact extreme smoke event European Arctic
2008/12/25
In spring 2006 a special meteorological situation occurred in the European Arctic region giving record high levels of air pollution. The synoptic situation resulted in extensive transport of pollution...
Boundary layer concentrations and landscape scale emissions of volatile organic compounds in early spring
boundary layer landscape scale emissions volatile organic compounds
2008/12/5
Boundary layer concentrations of several volatile organic compounds (VOC) were measured during two campaigns in springs of 2003 and 2006. The measurements were conducted over boreal landscapes near SM...
