Updated climatological mean ΔfCO2 and net sea–air CO2 flux over the global open ocean regions
The late Taro Takahashi (Lamont-Doherty Earth Observatory (LDEO), Columbia University) and colleagues provided the first near-global monthly air–sea CO 2 flux climatology in Takahashi et al. (1997), based on available surface water partial pressure of CO 2 measurements. This product has been a bench...

The late Taro Takahashi (Lamont-Doherty Earth Observatory (LDEO), Columbia University) and colleagues provided the first near-global monthly air–sea CO 2 flux climatology in Takahashi et al. (1997), based on available surface water partial pressure of CO 2 measurements. This product has been a benchmark for uptake of CO 2 in the ocean. Several versions have been provided since, with improvements in procedures and large increases in observations, culminating in the authoritative assessment in Takahashi et al. (2009a, b). Here we provide and document the last iteration using a greatly increased dataset (SOCATv2022) and determining fluxes using air–sea partial pressure differences as a climatological reference for the period 1980–2021 (Fay et al., 2023, https://doi.org/10.25921/295g-sn13 ).
