Dalsøren, Stig Bjørløw; Myhre, Cathrine Lund; Myhre, Gunnar; Gomez-Pelaez, Angel J.; Haslerud, Amund Søvde; Isaksen, Ivar S. A.; Weiss, Ray F.; Harth, Christina M. (Peer reviewed; Journal article, 2016)Observations at surface sites show an increase in global mean surface methane (CH4) of about 180 parts per billion (ppb) (above 10 %) over the period 1984–2012. Over this period there are large fluctuations in the annual ... -
