Established:

February 2000

The main objective of the atmospheric correction working group is to quantify the performance of existing atmospheric correction algorithms used by the various ocean-colour satellite sensors. Therefore, the derived products from various ocean-colour missions can be meaningfully compared and possibly merged. Since atmospheric correction is a key procedure in ocean-colour remote sensing, we need to know how derived ocean-colour products from one sensor can be best compared with those from other sensors. We want to quantify the differences among the performance of the atmospheric correction algorithms.

In order to compare atmospheric correction algorithms from different sensors, simulated data sets were generated for various atmosphere and ocean optical properties as well as for various solar and viewing geometries. These simulated data sets were distributed to members of the working group and were used to test the performance of atmospheric correction algorithms for MERIS, POLDER, OCTS/GLI, MODIS and SeaWiFS. Preliminary results have been obtained for Case 1 waters and a more complete comparison will be carried out in the near future.

Access to Synthesized Data Set
  • Synthesized Dataset from IOCCG Report 5. This dataset contains both inherent optical properties (IOPs) and apparent optical properties (AOPs) for testing and comparing algorithms, as in IOCCG Report 5. Please cite this report as follows if you use the dataset:
    IOCCG (2006). Remote Sensing of Inherent Optical Properties: Fundamentals, Tests of Algorithms, and Applications. Lee, Z.-P. (ed.), Reports of the International Ocean-Colour Coordinating Group, No. 5, IOCCG, Dartmouth, Canada.
  • Synthesized Dataset from IOCCG Report 10. This dataset was developed to compare the performance of various atmospheric correction algorithms. Data are provided for open ocean (Case-1) waters and for non- or weakly-absorbing aerosols (generally present in the open ocean). Examples from coastal Case-2 waters (sediment-dominated and yellow-substance dominated waters) and from strongly-absorbing aerosols are also provided. Please refer to IOCCG Report 10 for details and cite this report as follows if you use the dataset:
