Glyoxal vertical columns from GOME-2 backscattered light measurements and comparisons with a global model
GOME-2 backscattered light measurements a global model
2010/12/28
Glyoxal vertical column densities have been retrieved from nadir backscattered radiances measured from 2007 to 2009 by the spaceborne GOME-2/METOP-A sensor. The retrieval algorithm is based on the DOA...
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...
GOME-2 observations of oxygenated VOCs: what can we learn from the ratio glyoxal to formaldehyde on a global scale?
GOME-2 oxygenated VOCs the ratio glyoxal a global scale
2010/11/3
Collocated data sets of glyoxal (CHO.CHO) and formaldehyde (HCHO) were retrieved for the first time from measurements of the Global Ozone Monitoring Experiment-2 (GOME-2) during the first two years of...
The continental source of glyoxal estimated by the synergistic use of spaceborne measurements and inverse modelling
glyoxal spaceborne measurements inverse modelling
2009/11/19
Tropospheric glyoxal and formaldehyde columns retrieved from the SCIAMACHY satellite instrument in 2005 are used with the IMAGESv2 global chemistry-transport model and its adjoint in a two-compound in...
Temporal and spatial variability of glyoxal as observed from space
biogenic processes VOC glyoxal
2009/7/15
Glyoxal, CHO.CHO, is produced during the oxidation of volatile organic compounds, VOC, released by anthropogenic activities, biogenic processes and biomass burning. It has a short chemical lifetime of...
Glyoxal uptake on ammonium sulphate seed aerosol: reaction products and reversibility of uptake under dark and irradiated conditions
Glyoxal ammonium sulphate seed aerosol irradiated conditions
2009/6/2
Chamber studies of glyoxal uptake onto ammonium sulphate aerosol were performed under dark and irradiated conditions to gain further insight into processes controlling glyoxal uptake onto ambient aero...
Light-absorbing secondary organic material formed by glyoxal in aqueous aerosol mimics
Light-absorbing secondary organic material glyoxal aqueous aerosol mimics
2009/5/7
Light-absorbing and high-molecular-weight secondary organic products were observed to result from the reaction of glyoxal in mildly acidic (pH=4) aqueous inorganic salt solutions mimicking aqueous tro...
The direct detection of glyoxal (CHOCHO), the smallest α-dicarbonyl, in the open atmosphere by active differential optical absorption spectroscopy (DOAS) has recently been demonstrated (Volkamer et a...
The influence of natural and anthropogenic secondary sources on the glyoxal global distribution
anthropogenic secondary sources glyoxal
2008/11/17
Glyoxal, the smallest dicarbonyl, which has recently been observed from space, is expected to provide indications on volatile organic compounds (VOC) oxidation and secondary aerosol formation in the t...
