Regional MODIS Ocean Colour Van Diemen Gulf

This satellite data set compromises of 6057 daily MODIS-Aqua (NASA) image acquisitions covering the Van Diemen Gulf region, NT. MODIS Level 0 data (e.g. raw counts) were processed using NASA’s SeaWiFS Data Analysis System (SeaDAS) software package version 7.0. Most up-to-date calibration tables and other auxiliary inputs (e.g. meteorological information) where incorporated into the processing with SeaDAS to account for sensor degradation and to compute calibrated and geo-located radiances at Top-of-Atmosphere (TOA) as Level 2 outputs. These were subsequently re-projected from satellite swath geometry to an equal-rectangular grid (445 x 550 pixels) covering 130.5° E and 133° E in longitude and 11° S and 13° S in latitude. The re-projected data were further processed using CSIRO’s regionally tuned ocean colour algorithms based on Artificial Neural Network (ANN) atmospheric correction and adaptive Linear Matrix Inversion (aLMI) in-water retrieval.\n\nLineage: Processing details can be obtained from the following report:\n\nSchroeder T, Brando V., Blondeau-Patissier D., Clementson L., Anstee J., Thapar N. and King E, (2015) Remote sensing methods to map and monitor the condition of coastal habitats and other surrogates for biodiversity - Part B: Water quality mapping of the Van Diemen Gulf, Image Processing and data Analysis Report, CSIRO Oceans & Atmosphere Flagship, Australia.
