Chemical, physical, and optical evolution of biomass burning aerosols: a case study
biomass burning aerosols Chemical physical
2011/2/25
In-situ chemical composition measurements of ambient aerosols have been used for characterizing the evolution of submicron aerosols from a large anthropogenic biomass burning (BB) event in Israel. A h...
Formic acid above the Jungfraujoch during 1985–2007: observed variability, seasonality, but no long-term background evolution
Formic acid the Jungfraujoch 1985–2007 background evolution
2010/11/3
This paper reports on daytime total vertical column abundances of formic acid (HCOOH) above the Northern mid-latitude, high altitude Jungfraujoch station (Switzerland; 46.5° N, 8.0° E, 3580 m alt.). T...
Chemical evolution of secondary organic aerosol from OH-initiated heterogeneous oxidation
Chemical evolution secondary organic aerosol OH-initiated heterogeneous oxidation
2010/8/13
The heterogeneous oxidation of laboratory Secondary Organic Aerosol (SOA) particles by OH radicals was investigated. SOA particles, produced by reaction of α-pinene and O3, were exposed to OH radicals...

Airborne measurements aerosol chemical composition Europe the organic fraction
2010/8/12
The spatial distribution of aerosol chemical composition and the evolution of the Organic Aerosol (OA) fraction is investigated based upon airborne measurements of aerosol chemical composition in the ...
Influence of vortex dynamics and atmospheric turbulence on the early evolution of a contrail
vortex dynamics atmospheric turbulence the early evolution of a contrail
2010/8/12
This study describes three-dimensional numerical simulations of the evolution of an aircraft contrail during the first 30 min following the emission of exhausts. The wake is modeled as a vortex pair d...
The summertime “heat” low over Pakistan/northwestern India: evolution and origin
Heat low Desert heating Orographic forcing South Asian monsoon MONSOON DYNAMICS DESERT CLIMATE TROUGH SEA
2014/5/20
A deep low in sea-level pressure is present from May to September over Pakistan and northwestern India (hereafter, the Pak-India low). It is often referred as the "heat" low to convey the significance...
Wildfire smoke in the Siberian Arctic in summer: source characterization and plume evolution from airborne measurements
Wildfire smoke Siberian Arctic summer source characterization airborne measurements
2009/12/31
We present airborne measurements of carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), equivalent black carbon (EBC) and ultra fine particles over North-Eastern Siberia in July 2008 performed dur...
Investigating the evolution of major Northern Hemisphere ice sheets during the last glacial-interglacial cycle
Hemisphere ice sheets last glacial-interglacial cycle
2009/12/3
A 2.5-dimensional climate model of intermediate complexity, CLIMBER-2, fully coupled with the GREMLINS 3-D thermo-mechanical ice sheet model is used to simulate the evolution of major Northern Hemisph...
Evolution of Asian aerosols during transpacific transport in INTEX-B
Asian aerosols transpacific transport INTEX-B

Measurements of aerosol composition were made with an Aerodyne High Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS) on board the NSF/NCAR C-130 aircraft as part of the Intercontinenta...
Evolution of stratospheric ozone and water vapour time series studied with satellite measurements
stratospheric ozone water vapour time series satellite measurements
2009/8/25
The long term evolution of stratospheric ozone and water vapour has been investigated by extending satellite time series to April 2008. For ozone, we examine monthly average ozone values from various ...
