TLDR
A temporally and spatially resolved estimate of the global surface-ocean CO2 partial pressure field and the sea-air CO2 flux is presented, obtained by fitting a simple data-driven diagnostic model of ocean mixed-layer biogeochemistry to surface-of-the-atmosphere (CO2) partial pressure data from the SOCAT v15 database.Abstract:
A temporally and spatially resolved estimate of the global surface-ocean CO2 partial pressure field and the sea–air CO2 flux is presented, obtained by fitting a simple data-driven diagnostic model of ocean mixed-layer biogeochemistry to surface-ocean CO2 partial pressure data from the SOCAT v15 database Results include seasonal, interannual, and short-term (daily) variations In most regions, estimated seasonality is well constrained from the data, and compares well to the widely used monthly climatology by Takahashi et al (2009) Comparison to independent data tentatively supports the slightly higher seasonal variations in our estimates in some areas We also fitted the diagnostic model to atmospheric CO2 data The results of this are less robust, but in those areas where atmospheric signals are not strongly influenced by land flux variability, their seasonality is nevertheless consistent with the results based on surface-ocean data From a comparison with an independent seasonal climatology of surface-ocean nutrient concentration, the diagnostic model is shown to capture relevant surface-ocean biogeochemical processes reasonably well Estimated interannual variations will be presented and discussed in a companion paperread more

TL;DR: A time history of ocean-atmosphere CO2 fluxes from 1992 to 2018 is calculated, corrected for temperature gradients between the surface and sampling at a few meters depth, and suggests most ocean models underestimate uptake.

TL;DR: Measurements of the interhemispheric gradient of atmospheric carbon dioxide show that the Northern Hemisphere carbon land sink remained stable between the 1960s and the late 1980s, then increased during the 1990s and 2000s, underscore the importance of Northern Hemispheric land as a carbon sink.

TL;DR: In this article, the authors present a Moored Autonomous pCO2 (MAPCO2) system that provides high-resolution data that can measure interannual, seasonal, and sub-seasonal dynamics and constrain the impact of short-term biogeochemical variability on carbon dioxide flux.
