Journal ArticleDOI
Statistical clumped isotope signatures
TL;DR: In this paper, it was shown that negative clumped isotope anomalies (anti-clumping) occur when two or more indistinguishable atoms of the same element, but with different isotopic composition, combine in a molecule.
Journal ArticleDOI
Greenhouse gas observations from Cabauw Tall Tower (1992–2010)
TL;DR: In this paper, a semi-continuous in-situ observations of greenhouse gas concentrations have been performed at the tall tower of Cabauw (4.927° E, 51.971° N, −0.7 m a.s.l.).
Journal ArticleDOI

TL;DR: In this paper, a dual isotope ratio mass spectrometric system (IRMS) and a quantum cascade laser absorption spectroscopy (QCLAS)-based technique for in situ analysis of the isotopic composition of methane under field conditions were deployed at the Cabauw Experimental Site for Atmospheric Research (CESAR).
Journal ArticleDOI

Popa,David Lowry,Martin Steinbacher,Armin Jordan,Simon O'Doherty,Salvatore Piacentino,Edward J. Dlugokencky +25 more
TL;DR: In this paper, the authors use continuous observations from 10 European stations (including 5 tall towers) for CH4 and 9 continuous stations for N2O, complemented by additional European and global discrete air sampling sites.
Journal ArticleDOI
Vehicle emissions of greenhouse gases and related tracers from a tunnel study: CO : CO 2 , N 2 O : CO 2 , CH 4 : CO 2 , O 2 : CO 2 ratios, and the stable isotopes 13 C and 18 O in CO 2 and CO

TL;DR: In this paper, measurements of CO2, CO, N2O and CH4 mole fractions, O2 / N2 ratios and the stable isotopes 13C and 18O in CO2 and CO have been performed in air samples from the Islisberg highway tunnel (Switzerland).
