Remote sensing estimates of the ocean surface partial pressure of CO2 and air-sea CO2 fluxes in the Baltic Sea, 1998-2011

Ocean surface partial pressure of CO2 (pCO2) and air-sea CO2 fluxes in the Baltic Sea estimated using self-organizing map classifications along with class-specific linear regressions (SOMLO methodology). The estimates have a spatial resolution of 4-km both in latitude and longitude and a monthly temporal resolution from 1998 to 2011. The CO2 fluxes are estimated using reanalysis winds and the method of Wanninkhof et al. (2013). For more details see: Parard, G., Charantonis, A.
