Title: MODIS/Aqua Level 3 Global Ocean Mapped 4 KM Monthly Ocean Color Products
Description:
Abstract:
This data set consists of satellite measurements of global ocean color data obtained by the Moderate Resolution Imaging Spectroradiometer (MODIS), in orbit on the Aqua (formerly EOS PM) platform. MODIS ocean color products are processed and distributed by the Ocean Biology Processing Group (OBPG). Processing details can be found at http://oceancolor.gsfc.nasa.gov/DOCS/MODISA_processing.html The Aqua MODIS Level 3 standard mapped image (SMI) products are integer representations of binned data products. This image is an 8-bit, two-dimensional array of an Equidistant Cylindrical projection of the globe. (The capability to produce 16-bit SMI products has been implemented by the OBPG, and the MODIS Ocean Color products are expected to be regenerated as 16-bits values at the next reprocessing in about 1 year.) Each SMI product contains one image of a geophysical parameter and is stored in one physical HDF file. The Level 3 binned products are used to generate mapped data products on 4 and 9 km equi-rectangular projection. The products are generated for the following binning periods: Daily, 8-Day, Monthly, Monthly Climatology, Seasonal, Seasonal Climatology, Annual, Cumulative. Five SMI products are generated from each standard Ocean Color binned data product, one for each of the following geophysical parameters: -Chlorophyll-a concentration (CHLO) -Normalized water-leaving radiance at band 5 (L551) -Aerosol optical thickness at band 8 for atmospheric correction (T869) -Angstrom coefficient, 531-869 nm, for atmospheric correction (A531) -Diffuse attenuation coefficient at 490 nm (measure of optical clarity) (K490) Each SMI product represents data binned over the period covered by the parent product. The arithmetic mean is used in each case to obtain the values for the SMI grid points from the binned data products. More detailed information on the Level-3 Standard Mapped Image data product format specifications can be found in the document at http://oceancolor.gsfc.nasa.gov/DOCS/Ocean_Level-3_SMI_Products.pdf Please, read the MODIS Ocean Parent document for more details: http://gcmd.nasa.gov/getdif.htm?MODIS_OCEAN_PARENT Browse Level 3 Standard Mapped Images (SMI) at http://oceancolor.gsfc.nasa.gov/cgi/level3.pl The Aqua MODIS Level 3 Mapped data files are available from the FTP site at ftp://oceans.gsfc.nasa.gov/MODISA/Mapped/
