Short summary

This study reconstructs a complete field of summer sea surface partial pressure of CO₂ (pCO₂) over the South China Sea (SCS) with a 0.5° resolution in the period of 2000–2017 using the scattered underway pCO₂ observations. The spectral optimal gridding method was used in this reconstruction with empirical orthogonal functions computed from remote sensing data. Our reconstructed data show that the rate of sea surface pCO2 increase in the SCS is 2.4 ± 0.8 µatm yr^-1 during 2000–2017.
