Аннотация:The Surface Ocean CO2 Atlas (SOCAT) of CO2 fugacity (fCO2) observations is a key resource supporting annual assessments of CO2 uptake by the ocean and its side effects on the marine ecosystem. SOCAT data are usually released with a lag of up to 1.5 years which hampers timely quantification of recent variations of carbon fluxes between the Earth System components, not only with the ocean. This study uses a statistical ensemble approach to analyse fCO2 with a latency of one month only based on the previous SOCAT release and a series of predictors. A retrospective prediction for the years 2021-2022 is made to test the model skill, followed by the generation of fCO2 and fluxes from January to August in 2023. Results indicate a modest degradation of the model skill in prediction mode and open the possibility to provide robust information about marine carbonate system variables with low latency.
