Measurements of Gaseous NH3 and Particulate NH4 + in the Atmosphere by Fluorescent Detection after Continuous Air–water Droplet Sampling
Ammonia Gas-particle partitioning Microflow analysis Short-term variation
2016/3/28
Phase partitioning of NHx (gaseous NH3 and particulate NH4
+) in the atmosphere is crucial for the lifetime of NHx
during atmospheric transport. Reliable data for gaseous NH3 and NH4
+ in aerosols ...
Ship-based detection of glyoxal over the remote tropical Pacific Ocean
Ship-based detection glyoxal the remote tropical Pacific Ocean
2010/12/20
We present the first detection of glyoxal (CHOCHO) over the remote tropical Pacific Ocean in the Marine Boundary Layer (MBL). The measurements were conducted by means of the University of Colorado Shi...
The Eyjafjallajökull eruption in April 2010 – detection of volcanic plume using in-situ measurements, ozone sondes and lidar-ceilometer profiles
The Eyjafjallajö kull eruption April 2010 volcanic plume in-situ measurements ozone sondes lidar-ceilometer profiles
2010/11/3
Volcanic emissions from the Eyjafjallajökull volcano eruption on the Southern fringe of Iceland in April 2010 were detected at the Global Atmosphere Watch (GAW) station Zugspitze/Hohenpeissenberg...
Detection of dust aerosol by combining CALIPSO active lidar and passive IIR measurements
dust aerosol CALIPSO active lidar passive IIR measurements
2010/8/12
The version 2 Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) dust layer detection method, which is based only on lidar measurements, misclassified about 43% dust layers (...
Saharan dust events at the Jungfraujoch: detection by wavelength dependence of the single scattering albedo and first climatology analysis
Saharan dust events Jungfraujoch single scattering albedo climatology analysis
2009/3/10
Scattering and absorption coefficients have been measured continuously at several wavelengths since March 2001 at the high altitude site Jungfraujoch (3580ma.s.l.). From these data, the wavelength dep...
Retrieval of CO from SCIAMACHY onboard ENVISAT: detection of strongly polluted areas and seasonal patterns in global CO abundances

2009/2/6
Measurements of atmospheric volatile organic compounds were performed in the Finnish Boreal forest atmosphere during spring 2003, as part of the project QUEST (Quantification of Aerosol Nucleation in ...
Detection and measurement of total ozone from stellar spectra: Paper 2. Historic data from 1935–1942
total ozone stellar spectra
2009/1/9
Atmospheric ozone columns are derived from historic stellar spectra observed between 1935 and 1942 at Mount Wilson Observatory, California. Comparisons with contemporary measurements in the Arosa data...
Seasonal variation of peroxyacetylnitrate (PAN) in coastal Antarctica measured with a new instrument for the detection of sub-part per trillion mixing ratios of PAN
PAN coastal Antarctica
2008/12/18
An automated gas chromatograph with sample pre-concentration for the measurement of peroxyacetylnitrate (PAN) was constructed with a minimum detection limit below 1 pptv. This instrument was deployed ...
