Atmospheric ozone and carbon monoxide mixing ratios measured during the MR20-05C cruise of R/V Mirai

During the MR20-05C Arctic cruise of R/V Mirai, atmospheric ozone (O3) and carbon monoxide (CO) measurements were continuously conducted using a UV ozone analyzer (Model 205, 2B Tech) and an IR CO analyzer (Model 48iTLE, Thermo) located in the Research Information Center, to which ambient air was drawn through ~20-m-long Teflon tubes. See the header of the data files for more details. It is recommended to contact the investigators for any use.
