Modelling regional scale surface fluxes,meteorology and CO2 mixing ratios for the Cabauw tower in the Netherlands
regional scale surface fluxes meteorology CO2 mixing ratios Cabauw tower
2010/1/21
We simulated meteorology and atmospheric CO2 transport over the Netherlands with the mesoscale model RAMS-Leaf3 coupled to the biospheric CO2 flux model 5PM. The results were compared with meteorologi...
Mixing ratios and eddy covariance flux measurements of volatile organic compounds from an urban canopy
Mixing ratios eddy covariance flux measurements volatile organic urban canopy
2009/3/31
Mixing ratios and fluxes of six selected volatile organic compounds (VOCs) were measured above the city of Manchester (UK) during the summer of 2006. A proton transfer reaction-mass spectrometer was u...
Ozone mixing ratios inside tropical deep convective clouds from OMI satellite measurements
Ozone mixing ratios tropical deep convective clouds OMI satellite measurements
2009/3/12
We have developed a new technique for estimating ozone mixing ratio inside deep convective clouds. The technique uses the concept of an optical centroid cloud pressure that is indicative of the photon...
Seasonal variation of peroxyacetylnitrate (PAN) in coastal Antarctica measured with a new instrument for the detection of sub-part per trillion mixing ratios of PAN
PAN coastal Antarctica
2008/12/18
An automated gas chromatograph with sample pre-concentration for the measurement of peroxyacetylnitrate (PAN) was constructed with a minimum detection limit below 1 pptv. This instrument was deployed ...
Modelling representation errors of atmospheric CO2 mixing ratios at a regional scale
atmospheric CO2 regional scale

Inverse modelling of carbon sources and sinks requires an accurate quality estimate of the modelling framework to obtain a realistic estimate of the inferred fluxes and their uncertainties. So-called ...
Interpreting the variability of space-borne CO2 column-averaged volume mixing ratios over North America using a chemistry transport model
space-borne CO2 North America chemistry transport model
2008/11/21
We use the GEOS-Chem chemistry transport model to interpret the sources and sinks of CO2 that determine variability of column-averaged volume mixing ratios (CVMRs), as observed by the SCIAMACHY satell...
Technical Note: Determination of formaldehyde mixing ratios in air with PTR-MS: laboratory experiments and field measurements
Determination formaldehyde mixing ratios air PTR-MS laboratory experiments field measurements
2008/10/27
Formaldehyde (HCHO), the most abundant carbonyl compound in the atmosphere, is generated as an intermediate product in the oxidation of nonmethane hydrocarbons. Proton transfer reaction mass spectrome...
E2/M1 Multipole Mixing Ratios of Transitions in Erbium Isotopes
IBA-2 Deformation parameter Quadrupol moment Mixing ratios
2010/4/12
Erbium isotopes (Z = 64) lie in the transitional region that occurs at the middle of the range of deformed nuclei. g -ray E2/M1 mixing ratios for selected transitions in 166-168Er are calculated in th...
