Primary anthropogenic aerosol emission trends for China, 1990–2005
anthropogenic primary aerosol China a dynamic methodology
2011/2/25
An inventory of anthropogenic primary aerosol emissions in China was developed for 1990–2005 using a technology-based approach. Taking into account changes in the technology penetration within industr...
A very high-resolution (1 km×1 km) global fossil fuel CO2 emission inventory derived using a point source database and satellite observations of nighttime lights
a point source database satellite observations nighttime lights
2011/1/20
Emissions of CO2 from fossil fuel combustion are a critical quantity that must be accurately given in established flux inversion frameworks. Work with emerging satellite-based inversions requires spat...
Emission location dependent ozone depletion potentials for very short-lived halogenated species
Emission location ozone depletion potentials short-lived halogenated species
2010/12/28
We present trajectory-based estimates of Ozone Depletion Potentials (ODPs) for very short-lived halogenated source gases as a function of surface emission location. The ODPs are determined by the frac...
A refinement of the emission data for Kola Peninsula based on inverse dispersion modelling
the emission data Kola Peninsula inverse dispersion modelling
2010/11/30
The study reviews the emission estimates of sulphur oxides (SOx) and primary particulate matter (PM) from the major industrial sources of Kola Peninsula. Analysis of the disagreements between the exis...
Emission and dry deposition of accumulation mode particles in the Amazon Basin
mode particles the Amazon Basin
2010/11/29
Size-resolved vertical aerosol number fluxes of particles in the diameter range 0.25–2.5 μm were measured with the eddy covariance method from a 53 m high tower over the Amazon rain forest, 60 km NNW ...
Updated African biomass burning emission inventories in the framework of the AMMA-IDAF program, with an evaluation of combustion aerosols
African biomass burning emission the framework of the AMMA-IDAF program combustion aerosols
2010/10/21
African biomass burning emission inventories for gaseous and particulate species have been constructed at a resolution of 1 km by 1km with daily coverage for the 2000–2007 period. These inventories ar...
HFC-23 (CHF3) emission trend response to HCFC-22 (CHClF2) production and recent HFC-23 emission abatement measures
HFC-23 (CHF3) emission trend HCFC-22 (CHClF2) production recent HFC-23 emission abatement measures
2010/9/1
We present observations of lower-tropospheric mole fractions of HFC-23 measured by "Medusa" GC/MSD instruments from ambient air sampled in situ at the Advanced Global Atmospheric Gases Experiment (AGA...
Characterization of Tropospheric Emission Spectrometer (TES) CO2 for carbon cycle science
Tropospheric Emission Spectrometer CO2 carbon cycle science
2010/8/13
We present carbon dioxide (CO2) estimates from the Tropospheric Emission Spectrometer (TES) on the EOS-Aura satellite launched in 2004. For observations between 40° S and 45° N, we find about 1 degree...
Enhancement of marine cloud albedo via controlled sea spray injections: a global model study of the influence of emission rates, microphysics and transport
marine cloud albedo emission rates microphysics transport
2010/8/12
Modification of cloud albedo by controlled emission of sea spray particles into the atmosphere has been suggested as a possible geoengineering option to slow global warming. Previous global studies ha...
Particle number, particle mass and NOx emission factors at a highway and an urban street in Copenhagen
