To guarantee the data set is of good quality, the data have undergone an intensive validation process by comparing measurements from in-situ buoys. The conclusion was that the error statistics of the merged data are better than data from the three individual sensors.
In addition to aiding carbon cycle research, ocean colour data can provide oceanographers with the information they need to monitor the state of the oceans for other applications, such as for the fisheries and aquaculture industries.
GlobColour, part of ESAs Data User Element (DUE), will begin providing near-real time ocean colour observations to support this type of operational oceanography from mid-2008.
This service will continue well into the future, thanks to the European Commission (EC), who will continue production of the GlobColour time series from 2009 as part of the Marine Core Service of the GMES (Global Monitoring for Environment and Security) initiative.
"We need to sustain an international effort to make sure we can link one satellite dataset to another to build the long-time series that we need to distinguish change from cycles, and GlobColour is definitely a significant step in that perspective," said Dr James Yoder, Chair of the International Ocean-Colour Coordinating Group (IOCCG).
