This working group was proposed at the 8th IOCCG Meeting in Florence, Italy (February 2003), although a preliminary meeting was held in Santa Fe, November 2002, prior to the Ocean Optics Meeting.

The objectives of the group were to perform algorithm cross comparisons, to make recommendations on specific algorithms and to report on the progress of algorithm development.

The group assembled a database from in situ measurements and also developed a synthesized dataset based on known relationships, in order to perform algorithm cross-comparisons and evaluations. The synthesized datasets, as well as the software for the various algorithms, are available on the IOCCG webpage (see links to the right in red). The final product of this working group was the publication of IOCCG Report 5 entitled “Remote Sensing of Inherent Optical Properties: Fundamentals, Tests of Algorithms, and Applications”, edited by Dr. ZhongPing Lee.

Terms of Reference

  • Synthesize a database of inherent (IOP) and apparent optical properties (AOP), and assemble a database of in situ measurements.
  • Perform cross-comparisons and evaluations on existing ocean-colour inversion algorithms.
  • Make recommendations on specific algorithms.
  • Report on the progress of algorithm development.

Synthesized Dataset

  • Information on the synthesized dataset used in IOCCG Report 5 for testing and comparing ocean colour algorithms can be found at:  The dataset contains  both inherent optical properties (IOPs) and apparent optical properties (AOPs) .
