This study aims to develop a near real-time simulation system to assist in the preparation of the observational plan and the first analysis during the observational campaigns such as a cruise of the Research Vessel (R/V) Mirai. This system covers most of the Northern Hemisphere for the precise treatment of the intrusions of airmasses from the mid-latitudes to the Arctic. Day-to-day variations in the emissions are also taken into account, especially for emissions from biomass burning. The calculation is conducted using forecasted meteorological data for the target period, and the model data is finally overwritten by the output executed using the operational reanalysis data. The system has been applied to cruises of the R/V Mirai for MR1606 in 2016. Operationally, a 48-hour forecast calculation is conducted once a day and the result is shared with the researchers conducting the observations. Here, we present a dataset for the meteorological and atmospheric constituents, such as ozone and black carbon near the surface, during the MR1606 cruise of the R/V Mirai in 2016. This dataset can be used for the analysis of transport and transformation processes of chemical constituents that are observed during the cruise, and also the meteorological data can be used for the source analysis using trajectory models such as WRF-FLEXPART.
