Summary
Abstract: This data set consists of satellite measurements of global ocean color data
obtained by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS), in orbit on
the OrbView-2 (formerly SeaStar) platform. SeaWiFS 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/SW_proc.html

Each SeaWiFS Level-3 binned (9 km) data product consists of the accumulated
data for all Level-2 products, for the specified instrument and resolution,
corresponding to a period of one day, 8 days, a calendar month, a calendar
year, or the cumulative mission. Each Level-3 binned data product is stored in
one or more HDF files. The data are stored in a representation of a global,
equal-area grid whose grid cells, or "bins," have a resolution of 9.2x9.2km
(approximately 81 km2).

Each given time binning period (Daily, 8-Day, Monthly, Monthly Climatology,
Seasonal, Seasonal Climatology, Annual, Cumulative) has a separate file for
each product. These files include a main file containing all product-level
metadata, and data for each bin filled for that product and time period. In
addition, each product includes subordinate files, each of which contains data
of one binned geophysical parameter for all bins. Subordinate files must be
read in conjunction with the associated main file. The parameters are the
normalized water-leaving radiances (radiance data corrected for atmospheric
light scattering and sun angles differing from nadir), and geophysical
parameters derived from the radiance data.

SeaWiFS ocean color binned products consist of:
-Normalized water-leaving radiance at 412 nm [file x00 = nLw_412_sum]
-Normalized water-leaving radiance at 443 nm [file x01 = nLw_443_sum]
-Normalized water-leaving radiance at 490 nm [file x02 = nLw_490_sum]
-Normalized water-leaving radiance at 510 nm [file x03 = nLw_510_sum]
-Normalized water-leaving radiance at 555 nm [file x04 = nLw_555_sum]
-Normalized water-leaving radiance at 670 nm [file x05 = nLw_670_sum]
-Angstrom coefficient, 510-865 nm [file x06 = angstrom_510_sum]
-Chlorophyll-a concentration [file x07 = chlor_a_sum]
-Diffuse attenuation coefficient at 490 nm [file x08 = K_490_sum]
-Epsilon of aerosol correction at 765 and 865 nm [file x09 = eps_78_sum]
-Aerosol optical thickness at 865 nm [file x10 = tau_865_sum]

Access Constraints
From the start of instrument operations through January 1, 1998, all SeaWiFS
data is free and available to the public. Following January 1, 1998, SeaWiFS
data for scientific research will ONLY be available to Authorized Users who
have registered with the SeaWiFS Project. Any individual scientist who will be
conducting research that employs SeaWiFS data must be a registered Authorized
User. A single Authorized User cannot obtain data to be used anonymously by
members of a research group; all of the members of the group must be Authorized
Users.


Use Constraints
Publications of research results utilizing these data must acknowledge the
SeaWiFS Project and the Ocean Biology Processing Group (OBPG) at the NASA
Goddard Space Flight Center, Greenbelt, MD, USA.
