The goal of the IOCS meeting is to foster exchange between the research community and space agency representatives. The aim of many of the splinter sessions or breakout workshops is to develop concrete outputs that represent a synthesis of what our community needs in order to carry out state-of-the-art research and applications using ocean colour remote sensing. Recommendations emerging from these sessions are the result of discussion and consensus within the session.

The following is a synthesis of all the recommendations or action items that have emerged from these discussions since the IOCS meeting began in 2013. Active recommendations are displayed by topic, and each shows who was selected to execute the recommendation (whether the space agencies, the community, or the IOCCG) and its current status. Recommendations deemed to be completed are listed in the Completed Recommendations list, regardless of topic.

Active IOCS Recommendations by Topic

Atmospheric Correction

2013.08.2 The importance of involving National Reference Laboratories in the characterization of field radiometers and SI traceability of measurements is essential. Agency Ongoing
2013.08.3 The analysis of legacy constraints for in situ measurements and sites supporting system vicarious calibration suggests that spatial homogeneity of the measurement site(s) is an essential requirement. The constraint on the aerosol optical thickness lower than 0.1 in the visible could be likely “relaxed” as long as the atmospheric conditions are well characterized. It is additionally recommended that the availability of supplementary atmospheric measurements at the vicarious measurement site(s) (e.g., vertical characterizations of the atmospheric components) are of potential aid to system vicarious calibration. Agency Ongoing
2013.08.4 The use of commercial systems to support system vicarious calibration imposes the generation of in situ traceable measurements through fully characterized hyperspectral systems. This requires comprehensive characterizations of commercial hyperspectral systems whose performances often need thorough verification. Agency Ongoing
2013.08.5 The standardization of system vicarious calibration is a necessary strategy for the generation of CDRs from multiple satellite instruments. Current system vicarious calibration exercises involving NASA and ESA sensors appear to indicate that the lack of standardization between institutions (not only for the system vicarious calibration process) may lead to significant differences in derived satellite data products not compatible with the creation of CDRs from independent missions. However, standardization using current technologies should consider that forthcoming advanced systems like PACE may benefit from additional measurement capabilities (e.g., polarization) with respect to current space sensors. Agency Ongoing

Community EUMETSAT holds regular workshops to best identify and serve the community’s need
2013.12.2 A permanent calibration task force should be established to share expertise and information on instrument calibration and characterization. It should be supported by space agencies and should have close interaction with the extended ocean-colour community. It could be established either under the CEOS-IVOS framework, or the IOCCG/INSITU-OCR. IOCCG
2015.01.5 Exploit current hyperspectral satellite data as synergistic use to multispectral satellite data Community See Losa et al. (2017), but certainly this should be continued.
