DAY 2: January 30, 2001
- 1:30-5:30 SIMBIOS PROJECT OBJECTIVES ON DATA MERGING (2000-2003)
Bldg. 28, Room Skybox (N270) Chairman: TBD
Topics to be discussed: The first issue that this working group should address is to define what are the concrete objectives to achieve (i.e., what results and end products), now that various satellite ocean-color data sets are available and several ocean-color instruments are flying at the same time. The Project would like to propose two data merger examples of end products.
- 1) a climatology of chl-a that blends in-situ and satellite data i.e., monthly global fields on a typical 9 km grid. Satellite data input to start should be the first years of SeaWiFS data, OCTS and/or POLDER, and CZCS data, adding in other satellite data (i.e., MODIS, etc) later. The climatology could be updated every year or two, by including more data as they become available. The blending/interpolation methodology, based on neural networks or more classical concepts (Reynolds, 1988), should be general -- and the methodology could also be a deliverable. It would use either level 3 data (i.e., chl-a), or level 2 data using consistent bio-optical algorithms, or both. For example, Watson and Project could work on the techniques for blending level 3 data, and Stephane/Dave level 2 data. Comparison of the results from various techniques and the production of the climatology -- and its update, would be made by the SIMBIOS Project.
- 2) A set of products that blend data from several satellite ocean-color sensors flying at the same time, e.g., SeaWiFS and MODIS, with extension to MERIS and, then GLI, POLDER-2. These products, at the levels 2 and 3, would be similar to those produced by the SeaWiFS project (or perhaps a reduced number of them), but improved in quality because they will combine several data sets. They will not be a climatology, but a time series. The SIMBIOS Project would generate these improved products routinely, adding data from more sensors as they become available. Several approaches could be investigated to merge the products. This could be done (1) at the top-of-atmosphere level, where the data from one sensor would be mapped spectrally to that of a reference instrument (e.g., SeaWiFS) and then the same atmospheric correction applied, (2) using water-leaving radiances, obtained independently for each instrument, but with consistent atmospheric correction schemes, or (3) at level 3. The SIMBIOS Project will continue to address specific topics, namely (1) radiometric calibration (i.e., radiometric models and pre-launch calibration, post- launch onboard calibration, vicarious calibration); (2) evaluation of algorithms and products (i.e., bio-optical algorithms, and atmospheric correction), and (3) trails of merging techniques of satellite/other data sets. At the close of this meeting, the Project would like to identify a small executive team for data merging activities for the 2000-2003. Membership to this team will be by appointment and renewal each year. A tight scientific collaboration is envisioned with stages requiring visits to GSFC. The role of the SIMBIOS Project is to implement the approaches provided by the science team and executive team.
