SeaWiFS Level 3 Global Mapped 9 KM Weekly Photosynthetically Active Radiation (PAR) Data

[ Get Data ]

Abstract: This data set consists of algorithm estimates of global Photosynthetically
Active Radiation (PAR) reaching the surface obtained by the Sea-viewing Wide
Field-of-view Sensor (SeaWiFS), in orbit on the OrbView-2 (formerly SeaStar)
platform. SeaWiFS data products are processed and distributed by the Ocean
Biology Processing Group (OBPG). Processing details can be found at

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
Use Constraints Publications of research results utilizing these data must acknowledge the
SeaWiFS Project and the Ocean Biology Processing Group (OBPG) at the NASA
