MODIS / Aqua Calcite Concentration Products
Global Ehux products illustrate the presence/absence, areal extent, and timing of blooms of the sentinel coccolithophorid species Emilliania huxleyi (a calcite producing single-celled algae) and the resulting calcite concentration. The shown products below are 8-day composites maps of calcite concentrations on globe (4k resolution) and twenty-four regions (1 km resolution) from Aqua MODIS data by using the algorithm developed by Brown and Yoder (1994).
Important Message: The generation of global MODIS/Aqua Emiliania huxleyi bloom and calcite concentration products will be terminated on 22 May 2014 unless a NOAA operational user for either of these products is identified prior to this date. Also, the products have been reduced from 24 regions (global coverage) to six regions since 6 March 2014. At your earliest convenience, please let Dr. Banghua Yan (Banghua.Yan@noaa.gov) or Dr. Christopher W. Brown (Christopher.W.Brown@noaa.gov) know if you are using, or plan to use, either the MODIS/Aqua E. huxleyi bloom map or the calcite concentration product in a NOAA operational program and/or model. This need will help us continue generation of these products on the Okeanos system.
