Atmospheric methane and carbon dioxide concentrations measured during POSEIDON cruise POS533, 2019-03-02

Gas inlets were installed at the bow, on the top deck and in the mast of RV Poseidon. Atmospheric gas concentrations of CH4 and CO2 were measured continuously with a Picarro G2301-f analyzer. Concentrations are given as \"ppmV in dry air\".海神号科考船（RV Poseidon）的船首、上层甲板及桅杆处均安装了气体采样进气口。 采用Picarro G2301-f型分析仪对大气中甲烷（CH₄）与二氧化碳（CO₂）的浓度进行连续监测。 浓度以"干燥空气中的ppmV"为单位给出。
