Recently, global increase of the atmospheric methane concentration has been reported. However, few data on methane distribution covering a wide area are available. We have been developing an instrument which enables us to observe methane concentration with high time resolution, and we are trying to observe the methane distribution. The instrument utilizes the absorption of He-Ne laser light (}, title = {Series of observations of atmospheric methane aboard the icebreaker SHIRASE (abstract)}, volume = {7}, year = {1993} }
