Global distributions of methanol and formic acid retrieved for the first time from the IASI/MetOp thermal infrared sounder
formic acid the IASI/MetOp thermal infrared sounder
2011/2/24
Methanol (CH3OH) and formic acid (HCOOH) are among the most abundant volatile organic compounds present in the atmosphere. In this work, we derive the global distributions of these two organic species...
Flux estimates of isoprene, methanol and acetone from airborne PTR-MS measurements over the tropical rainforest during the GABRIEL 2005 campaign
Flux estimates isoprene methanol airborne PTR-MS tropical rainforest
2009/7/15
Tropical forests are a strong source of biogenic volatile organic compounds (BVOCs) to the atmosphere which can potentially impact the atmospheric oxidation capacity. Here we present airborne and grou...
Atmospheric methanol measurement using selective catalytic methanol to formaldehyde conversion
Atmospheric methanol selective catalytic methanol formaldehyde conversion
2009/2/18
A novel atmospheric methanol measurement technique, employing selective gas-phase catalytic conversion of methanol to formaldehyde followed by detection of the formaldehyde product, has been developed...
Sources and sinks of acetone, methanol, and acetaldehyde in North Atlantic marine air
sinks acetone methanol acetaldehyde North Atlantic marine air
2009/2/12
Measurements of acetone, methanol, acetaldehyde and a range of non-methane hydrocarbons have been made in North Atlantic marine air at the Mace Head observatory. Under maritime conditions the combina...
Oxygenated compounds in aged biomass burning plumes over the Eastern Mediterranean: evidence for strong secondary production of methanol and acetone
Oxygenated compounds Eastern Mediterranean methanol acetone
2009/1/23
Airborne measurements of acetone, methanol, PAN, acetonitrile (by Proton Transfer Reaction Mass Spectrometry), and CO (by Tunable Diode Laser Absorption Spectroscopy) have been performed during the Me...
The influence of biogenic emissions on upper-tropospheric methanol as revealed from space
biogenic emissions upper-tropospheric methanol
2008/12/29
The distribution and budget of oxygenated organic compounds in the atmosphere and their impact on tropospheric chemistry are still poorly constrained. Near-global space-borne measurements of seasonall...
A fate for organic acids, formaldehyde and methanol in cloud water: their biotransformation by micro-organisms
organic acids formaldehyde cloud water biotransformation micro-organisms
2008/12/16
The interactions between microbial and chemical contents of cloud water were investigated. First, we observe that the bulk cloud water solution provides a substantial environment where bacteria can de...
Cloud condensation nucleus (CCN) behavior of organic aerosol particles generated by atomization of water and methanol solutions
Cloud condensation nucleus organic aerosol particles atomization methanol
2008/12/11
Cloud condensation nucleus (CCN) experiments were carried out for malonic acid, succinic acid, oxalacetic acid, DL-malic acid, glutaric acid, DL-glutamic acid monohydrate, and adipic acid, using both ...
Air-sea fluxes of methanol, acetone, acetaldehyde, isoprene and DMS from a Norwegian fjord following a phytoplankton bloom in a mesocosm experiment
methanol acetone acetaldehyde Norwegian fjord phytoplankton
2008/12/1
The ocean's influence on volatile organic compounds (VOCs) in the atmosphere is poorly understood. This work characterises the oceanic emission and/or uptake of methanol, acetone, acetaldehyde, isopre...
