Hernandez-Carrasco et al present an interesting new approach to map the partial pressure of CO2 in the surface ocean and the resulting air-sea gas flux, using satellite data. The authors convincingly show that their new high resolution approach obtains better results than a low resolution product (CARBONTRACKER) in the Benguela system when being compared to in-situ observations. The manuscript ...

Interactive comment on “Reconstruction of super-resolution fields of ocean pCO2 and air–sea fluxes of CO2 from satellite imagery in the Southeastern Atlantic” by I. Hernández-Carrasco

Reviewer: The manuscript uses a combination of remotely sensed low-res air-sea CO2 flux and high-res Chl-a and SST to arrive at high-res air-sea CO2 fluxes. The authors present a method new to this application and the publication fits within the scope of BGD. The manuscript is well written and is relatively error-free with a few inconsistencies in abbreviations. The methodology presented to arr...

Denitrification effects on air-sea CO2 flux in the coastal ocean: Simulations for the northwest North Atlantic

[1] The contribution of coastal oceans to the global air-sea CO2 flux is poorly quantified due to insufficient availability of observations and inherent variability of physical, biological and chemical processes. We present simulated air-sea CO2 fluxes from a high-resolution biogeochemical model for the North American east coast continental shelves, a region characterized by significant sedimen...

Simulation and assimilation of global ocean pCO2 and air–sea CO2 fluxes using ship observations of surface ocean pCO2 in a simplified biogeochemical offline model

We used an offline tracer transport model, driven by reanalysis ocean currents and coupled to a simple biogeochemical model, to synthesize the surface ocean pCO2 and air–sea CO2 flux of the global ocean from 1996 to 2004, using a variational assimilation method. This oceanic CO2 flux analysis system was developed at the National Institute for Environmental Studies (NIES), Japan, as part of a pr...
