In situ and simultaneous measurement of the three most abundant isotopologues of
methane using mid-infrared laser absorption spectroscopy is demonstrated. A field …

We report results from a worldwide interlaboratory comparison of samples among
laboratories that measure (or measured) stable carbon and hydrogen isotope ratios of …

Little is known about how the methane source inventory and sinks have evolved over recent
centuries. New and detailed records of methane mixing ratio and isotopic composition (12 …

We present methane mixing ratio and δ13C time series measured at Baring Head, New
Zealand, and Scott Base, Antarctica, over the years 1991–2003. These data demonstrate …

Estimates of methane wildfire emissions from Northeast Eurasia for years 2000–2011 are
reported on the basis of satellite burned area data from the Moderate Resolution Imaging …

This study investigates the contribution of different CH4 sources to the seasonal cycle of δ
13 C during 2000–2012 by using the TM5 atmospheric transport model, including spatially …

В последние десятилетия резко увеличилось содержание в атмосфере парниковых
газов в основном антропогенного происхождения. Это связано не только с ростом …

Рассматриваются источники, трансформация в атмосфере и стоки газов, из которых
образуется озон в тропосфере. Показано, что основными газами-предшественниками …
