During the winter component of the SPORT (Seasonal Particle Observations in the Region of Toronto) field campaign, particulate non-refractory chemical composition and concentration of selected volatil...
Emissions and ambient distributions of Biogenic Volatile Organic Compounds（BVOC）in a ponderosa pine ecosystem: interpretation of PTR-MS mass spectra
Biogenic Volatile Organic Compounds BVOC ponderosa pine ecosystem PTR-MS mass spectra
2010/2/21
Two proton-transfer-reaction mass spectrometry systems were deployed at the Bio-hydro-atmosphere interactions of Energy, Aerosols, Carbon, H2O, Organics and Nitrogen-Southern Rocky Mountain 2008 field...
Influence of line mixing on the retrievals of atmospheric CO2 from spectra in the 1.6 and 2.1 μm regions
line mixing atmospheric CO2 spectra
2009/10/9
We present the first study of the influence of line mixing among CO2 lines on the remote sensing retrieval of atmospheric carbon dioxide. This is done in the bands near 1.6 and 2.1 μm which will be us...
The UV-A and visible solar irradiance spectrum: inter-comparison of absolutely calibrated, spectrally medium resolution solar irradiance spectra from balloon- and satellite-borne measurements
UV-A and visible solar irradiance spectrum spectrally medium resolution solar irradiance spectra
2009/2/12
Within the framework of the ENVISAT/-SCIAMACHY satellite validation, solar irradiance spectra are absolutely measured at moderate resolution in the UV/visible spectral range (in the UV from 316.7-418...
Iterative maximum a posteriori (IMAP)-DOAS for retrieval of strongly absorbing trace gases: Model studies for CH4 and CO2 retrieval from near infrared spectra of SCIAMACHY onboard ENVISAT
(IMAP)-DOAS trace gases CH4 CO2 infrared spectra SCIAMACHY onboard ENVISAT
2009/1/23
In the past, differential optical absorption spectroscopy (DOAS) has mostly been employed for atmospheric trace gas retrieval in the UV/Vis spectral region. New spectrometers such as SCIAMACHY onboard...
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...
Source apportionment of submicron organic aerosols at an urban site by factor analytical modelling of aerosol mass spectra
submicron organic aerosols aerosol mass spectra
2008/12/4
Submicron ambient aerosol was characterized in summer 2005 at an urban background site in Zurich, Switzerland, during a three-week measurement campaign. Highly time-resolved samples of non-refractory ...
Error analysis for CO and CH4 total column retrievals from SCIAMACHY 2.3 μm spectra
CO CH4 SCIAMACHY 2.3 μm spectra
2008/11/13
A detailed sensitivity analysis of the Iterative Maximum Likelihood Method (IMLM) algorithm and its application to the SCIAMACHY 2.3 μm spectra is presented. The sensitivity analysis includes a detail...
