Short summary
Based on the intercomparison of photoacoustic and cavity attenuation phase shift instruments, this paper has corrected and calibrated the data of recent field measurements. It showed good agreement and close correlation in the optical properties measured from different optical methods, and the scattering coefficient plays a crucial role as the bridge in constructing correlation between both instruments.
