GlobColour demonstration products
Several demonstration products have been generated for testing
and user feedback.
Photosynthetically Active Radiation (PAR)
A daily PAR estimate is obtained for each instantaneous pixel,
assuming the cloud/surface system is stable during the day and
corresponds to the satellite observation. Daily PAR estimates
obtained separately from different orbits and individual sensors
are binned using a simple, linear averaging scheme (arithmetical
mean).
The GlobColour PAR demonstration product is based on a merged
MERIS/SeaWiFS PAR product.
