Regular deployments of a scientific mooring are being made off the coast of Hawai'i.  Data from one of the instruments on this mooring, an OCI-200 irradiance meter (Satlantic, Inc.) are presented here.  This instrument measures downwelling irradiance at seven visible wavebands. 

This website describes the instrument used, deployment procedures and locations, and the resulting data.  The data from these measurements may also be downloaded from this site if desired.  This effort is part of the HALE-ALOHA (Hawaii Air-sea Logging Experiment, A Long-term Oligotrophic Habitat Assessment) study.
