SeaWiFS calibration: status after two years on orbit

The SeaWiFS Project has corrected the instrument calibration for drifts in the response of bands 1, 2, and 5-8 using lunar calibration data and has performed a vicarious calibration of SeaWiFS using in situ data from the Marine Optical Buoy deployed off of Lanai, Hawaii. This vicarious calibration has been validated by comparing SeaWiFS data with in situ data from various ship cruises. The calibration has also been validated through a global clear water analysis. Since the validation data come from regions of the ocean other than the MOBY site, the agreement between the SeaWiFS data in the validation data show that the vicarious calibration of SeaWiFS is a global calibration.
