Methane data collected in the 36th CHINARE cruise during 2019-2020
Methane (CH 4 ) is one of the important greenhouse gases. CH 4 dry mole fractions in the atmosphere have increased continuously since the onset of the industrial revolution, contributing to more than 20% of the anthropogenic radiative forcing in the lower atmosphere since 1750. In addition, the ice-...
