Short summary

We present a pCO₂ climatology of the Baltic Sea using a new approach to extrapolate from individual observations to the entire Baltic Sea. The extrapolation approach uses (a) a model to inform on how data at one location are connected to data at other locations, together with (b) very accurate pCO₂ observations from 2003 to 2021 as the base data. The climatology can be used e.g. to assess uptake and release of CO₂ or to identify extreme events.
