Summary • There are some inconsistencies in the OWT-based distributions of IOPs between NOMAD and the IOCCG simulated data set. • Both data sets are skewed towards coastal/case 2 waters. • Both data sets have some questions regarding the spectral slope of CDOM. • If a new simulated data set is being considered, the generation of IOPs and IOP pairs could be further constrained by the variance and co-variance as seen in NOMAD within different OWTs. • In addition, the representation of data points could be guided by the global distribution of naturally occurring OWTs.
