CO2, δO2/N2 and APO: observations from the Lutjewad, Mace Head and F3 platform flask sampling network
CO2, δO2/N2 and APO the Lutjewad, Mace Head and F3 platform flask sampling network
2010/11/30
We report results from our atmospheric flask sampling network for three European sites: Lutjewad in the Netherlands, Mace Head in Ireland and the North Sea F3 platform. The air samples from these stat...
Surface pressure retrieval from SCIAMACHY measurements in the O2 A Band: validation of the measurements and sensitivity on aerosols
Surface pressure retrieval sensitivity aerosols
2009/2/16
We perform surface pressure retrievals from cloud-free Oxygen A band measurements of SCIAMACHY. These retrievals can be well validated because surface pressure is a quantity that is, in general, accu...
Measurements of CO2, its stable isotopes, O2/N2, and 222Rn at Bern, Switzerland
Measurements of CO2 stable isotopes O2/N2 222Rn Switzerland
2009/1/8
A one-year time series of atmospheric CO2 measurements from Bern, Switzerland, is presented. O2/N2 and Ar/N2 ratios as well as stable carbon and oxygen isotopes of CO2 and δ29N2, δ34O2 and δ36Ar were ...
Atmospheric deuterium fractionation：HCHO and HCDO yields in the CH2DO + O2 reaction
Atmospheric deuterium fractionation HCHO HCDO yields CH2DO + O2 reaction
2008/12/25
The formation of formaldehyde via hydrogen atom transfer from the methoxy radical to molecular oxygen is a key step in the atmospheric photochemical oxidation of methane, and in the propagation of deu...
Consecutive reactions of aromatic-OH adducts with NO, NO2 and O2: benzene, naphthalene, toluene, m- and p-xylene, hexamethylbenzene, phenol, m-cresol and aniline
aromatic-OH adduct benzene naphthalene p-xylene hexamethylbenzene phenol
2008/12/8
Consecutive reactions of adducts, resulting from OH radicals and aromatics, with the tropospheric scavenger molecules O2, NO and NO2 have been studied for benzene, naphthalene, toluene, m- and p-xylen...
Investigations of the photochemical isotope equilibrium between O2, CO2 and O3
photochemical isotope equilibrium O2 CO2 O3
2008/11/28
Contrary to tropospheric CO2 whose oxygen isotopic composition follows a standard mass dependent relationship, i.e. δ17O~0.5δ18O, stratospheric CO2 is preferentially enriched in 17O, leading to a stri...
FRESCO+: an improved O2 A-band cloud retrieval algorithm for tropospheric trace gas retrievals
O2 A-band cloud tropospheric trace gas
2008/11/25
The FRESCO (Fast Retrieval Scheme for Clouds from the Oxygen A-band) algorithm has been used to retrieve cloud information from measurements of the O2 A-band around 760 nm by GOME, SCIAMACHY and GOME-...
Direct detection of OH formation in the reactions of HO2 with CH3C(O)O2 and other substituted peroxy radicals
OH HO2 CH3C(O)O2 substituted peroxy radicals
2008/11/17
This work details the first direct observation of OH as a product from (R1): HO2+CH3C(O)O2→(products), which has generally been considered an atmospheric radical termination process. The technique of ...
