Spatial variability of POPs in European background air
Spatial variability POPs European background air
2011/2/25
Passive air samplers (PAS) were deployed at 86 European background sites during summer 2006 in order (i) to gain further insight into spatial patterns of persistent organic pollutants (POPs) in Europe...
Observed 20th century desert dust variability: impact on climate and biogeochemistry
20th century desert dust climate and biogeochemistry
2010/11/30
Desert dust perturbs climate by directly and indirectly interacting with incoming solar and outgoing long wave radiation, thereby changing precipitation and temperature, in addition to modifying ocean...
A modelling study of photochemical regimes over Europe: robustness and variability
photochemical regimes Europe robustness and variability
2010/11/3
The variability of the relative sensitivity of photochemical ozone formation to volatile organic compounds (VOC) and NOx emissions, the chemical regime, over Europe during summers 2001 to 2003 is simu...
High variability of the heterogeneous ice nucleation potential of oxalic acid dihydrate and sodium oxalate
the heterogeneous ice nucleation oxalic acid dihydrate sodium oxalate
2010/8/25
The heterogeneous ice nucleation potential of airborne oxalic acid dihydrate and sodium oxalate particles in the deposition and condensation mode has been investigated by controlled expansion cooling ...
An investigation of the sub-grid variability of trace gases and aerosols for global climate modeling
the sub-grid variability trace gases and aerosols global climate modeling
2010/8/16
One fundamental property and limitation of grid based models is their inability to identify spatial details smaller than the grid cell size. While decades of work have gone into developing sub-grid tr...
Atmospheric deposition of mercury and major ions to the Pensacola (Florida) watershed: spatial, seasonal, and inter-annual variability
mercury major ions the Pensacola (Florida) watershed inter-annual variability
2010/8/13
Atmospheric deposition was measured at three sites in the Pensacola Bay watershed, Florida, between November 2004 and December 2007. Mercury deposition in the Pensacola Bay watershed was similar to th...
Variability of springtime transpacific pollution transport during 2000–2006: the INTEX-B mission in the context of previous years
springtime transpacific pollution INTEX-B mission
2010/2/21
We analyze the transport of pollution across the Pacific during the NASA INTEX-B (Intercontinental Chemical Transport Experiment Part B) campaign in spring 2006 and examine how this year compares to t...
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...
Physical and optical properties of aerosols over an urban location in Spain: seasonal and diurnal variability
Physical and optical properties aerosols Spain
2010/1/18
Measurements of aerosol optical properties and aerosol number size distribution obtained during the period from December 2005 to November 2007 at Granada, an urban site in south-eastern Spain, are ana...
Sources of Holocene variability of oxygen isotopes in paleoclimate archives
Holocene variability paleoclimate archives oxygen isotopes
2009/12/3
Variability in water isotopes has been captured in numerous archives and used to infer past climate changes. Here we examine water isotope variability over the course of the Holocene using the water-...
What drives the observed variability of HCN in the troposphere and lower stratosphere?

2009/11/19
We use the GEOS-Chem global 3-D chemistry transport model to investigate the relative importance of chemical and physical processes that determine observed variability of hydrogen cyanide (HCN) in the...
On the two-day oscillations and the day-to-day variability in global 3-D-modeling of the chemical system of the upper mesosphere/mesopause region
two-day oscillations day-to-day variability global 3-D-modeling chemical system
2009/11/11
The integration of the photochemical system of the upper mesosphere/mesopause region brought evidence that the system is able to respond in a nonlinear manner under certain conditions. Under the actio...
