Airborne glyoxal measurements in the marine and continental atmosphere: comparison with TROPOMI observations and EMAC simulations [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
We report on airborne limb and nadir measurements of vertical profiles and total vertical column densities (VCDs) of glyoxal (C2H2O2) in the troposphere, which were performed aboard the German research aircraft HALO (High Altitude and LOng Range) in ...

Mechanisms for Simultaneous Removal of Formaldehyde and Glyoxal by Amino Acids and Cytotoxicity of Their Products [PDF]

open access: yesShipin Kexue, 2023
This study aimed to investigate the mechanisms by which amino acids simultaneously remove formaldehyde and glyoxal and to evaluate the cytotoxicity of their products.

Observations and modelling of glyoxal in the tropical Atlantic marine boundary layer [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
In situ field measurements of glyoxal at the surface in the tropical marine boundary layer have been made with a temporal resolution of a few minutes during two 4-week campaigns in June–July and August–September 2014 at the Cape Verde Atmospheric ...

Photochemical modeling of glyoxal at a rural site: observations and analysis from BEARPEX 2007 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
We present roughly one month of high time-resolution, direct, in situ measurements of gas-phase glyoxal acquired during the BEARPEX 2007 field campaign. The research site, located on a ponderosa pine plantation in the Sierra Nevada mountains, is strongly

Primary emissions of glyoxal and methylglyoxal from laboratory measurements of open biomass burning [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
We report the emissions of glyoxal and methylglyoxal from the open burning of biomass during the NOAA-led 2016 FIREX intensive at the Fire Sciences Laboratory in Missoula, MT.

Comparison of Gas–Particle Partitioning of Glyoxal and Methylglyoxal in the Summertime Atmosphere at the Foot and Top of Mount Hua

open access: yesMolecules, 2023
Glyoxal and methylglyoxal are important volatile organic compounds in the atmosphere. The gas–particle partitioning of these carbonyl compounds makes significant contributions to O3 formation.

Instrument intercomparison of glyoxal, methyl glyoxal and NO2 under simulated atmospheric conditions [PDF]

open access: yesAtmospheric Measurement Techniques, 2015
The α-dicarbonyl compounds glyoxal (CHOCHO) and methyl glyoxal (CH3C(O)CHO) are produced in the atmosphere by the oxidation of hydrocarbons and emitted directly from pyrogenic sources.

Measurements of diurnal variations and eddy covariance (EC) fluxes of glyoxal in the tropical marine boundary layer: description of the Fast LED-CE-DOAS instrument [PDF]

open access: yesAtmospheric Measurement Techniques, 2014
Here we present first eddy covariance (EC) measurements of fluxes of glyoxal, the smallest α-dicarbonyl product of hydrocarbon oxidation, and a precursor for secondary organic aerosol (SOA).

Glyoxal vertical columns from GOME-2 backscattered light measurements and comparisons with a global model [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
Glyoxal vertical column densities have been retrieved from nadir backscattered radiances measured from 2007 to 2009 by the spaceborne GOME-2/METOP-A sensor.

Satellite Evidence for Glyoxal Depletion in Elevated Fire Plumes

open access: yesGeophysical Research Letters, 2023
Space‐borne observations are used to characterize the fate of formaldehyde and glyoxal in wildfire plumes. Their distribution measured by the Tropospheric Monitoring Instrument reveals striking differences between the two compounds near intense fires. In
