This data release includes in situ measurements collected between 2010 and 2014 during different cruise missions and study sites (Full description of the methods adopted for each measurements in the references). Measurements include concentrations of Particulate Organic Carbon (POC) (μgL-1) and Suspended Particulate Matter (SPM) (mg/l), remote-sensing reflectances (Rrs, sr-1), the particulate backscattering coefficient (bbp), and the particulate attenuation coefficient (cp) (m-1) at 650 nm. The first in situ database, named DS0, includes 300 coincident in situ POC, SPM, bbp, and cp measurements. DS1 includes 325 coincident in situ POC, SPM and Rrs.It addressed two main objectives:1) Check the relationship between POC/SPM and bbp/cp2) Develop a POC/SPM algorithm based on Rrs
