The NASA OBPG routinely downloads data from the AERONET-Ocean Color website for use in satellite sensor validation match-up analysis. As described by Zibordi et al. (2009), the AERONET-OC network consists of globally distributed autonomous radiometer systems maintained at fixed offshore sites. Please refer to the rest of the information in this article for details on how to acknowledge the use of AERONET-OC data and how the OBPG processes these data.

AERONET-OC data have a usage policy stated on the web sites for the individual AERONET-OC stations (linked below). Please consult the following links, however at the time this Wiki article was written, the summary of the AERONET-OC policy is:
Due to the research and development phase characterizing AERONET Ocean Color, use of these data requires offering co-authorship to the Principal Investigator. If you intend to use the following data please consult with the Principal Investigator(s) of the particular AERONET-OC site.
A column called "cruise_name" is present in the data files you can download after performing a Validation Search. These names have been specially created by SeaBASS staff to include certain identifying information. These names all use the following structure:
Cruise names contain descriptions that correspond to the following site names which are linked to the individual AERONET-OC sites with the contact information for the PI(s) at each site.

The OBPG uses normalized water leaving radiances (Lwn) downloaded from the AERONET-OC website. Remote Sensing Reflectance (Rrs) is calculated by dividing Lwn by the solar constant and then validation is performed on those values as described by Bailey and Werdell (2006).
