These measurements at discrete wavelengths represent the spectrum of light leaving the water surface, and the shape of the spectrum is characteristic of the water optical properties. Moore et al. (2009, RSE, 113, pp2424-2430, doi:10.1016/j.rse.2009.07.016) applied a clustering technique to spectra to identify 8 sets of discrete optical water types for data from the MODIS sensor. This product "owtd_csiro" is produced using a CSIRO implementation of the Moore et al. algorithm, and testing shows that it closely reproduces the results of the original Moore et al implementation in the NASA SeaDAS package. The CSIRO implementation was created because the implementation in SeaDAS has not been kept up to date, and to extend the product to the VIIRS sensor. {"type": "Polygon", "coordinates": [[[80.0, -60.0], [179.9, -60.0], [179.9, 10.0], [80.0, 10.0], [80.0, -60.0]]]} 80.0 179.9 -60.0 10.0 Countries | Australia Countries | Fiji Countries | Indonesia Countries | Malaysia Countries | New Caledonia Countries | New Zealand Countries | Papua New Guinea Countries | Philippines Countries | Timor-Leste Countries | Vanuatu Global / Oceans | Indian Ocean Global / Oceans | Pacific Ocean Global / Oceans | Southern Ocean Marine Features (Australia) | Bass Strait, TAS/VIC Marine Features (Australia) | Great Australian Bight, SA/WA Oceans | Ocean Optics | Ocean Color Regional Seas | Arafura Sea Regional Seas | Banda Sea Regional Seas | Celebes Sea Regional Seas | Coral Sea Regional Seas | Java Sea Regional Seas | Philippine Sea Regional Seas | Solomon Sea Regional Seas | Tasman Sea Regional Seas | Timor Sea States, Territories (Australia) | New South Wales States, Territories (Australia) | Northern Territory States, Territories (Australia) | Queensland States, Territories (Australia) | South Australia States, Territories (Australia) | Tasmania States, Territories (Australia) | Victoria States, Territories (Australia) | Western Australia Link to OPENDAP server documentDigital HTML Satellite Remote Sensing page on IMOS website documentDigital HTML Moore et al. 2009 paper documentDigital HTML srs_oc_snpp_owtd_csiro_url/owtd_csiro documentDigital SRS - OWTD - WMS layer HTML srs_oc_snpp_owtd_csiro_url documentDigital The GoGoDuck subsets and aggregates gridded data.
