 Is one of the first step of the preprocessing of a Nemo configuration. The interpolation onto the model grid has been conducted by taking all the original grid points falling into an NEMO grid box, and taking the median of those points.It s possible to choose the mean operator also. This procedure produces a smoothing of the sub-grid scale topography.

+* Seawiffs data : SeaWiFS had 8 spectral bands from 412 to 865 nm. It collected global data at 4 km resolution, and local data (limited onboard storage and direct broadcast) at 1 km. The mission and sensor were optimized for ocean color measurements, with a local noon (descending) equator crossing time orbit, fore-and-aft tilt capability, full dynamic range, and low polarization sensitivity. Chlorophyll concentration is expressed in units of mg m-3, indicating the concentration of the photosynthetic pigment chlorophyll a (also called CHLA) (the most common "green" chlorophyll) in ocean, estuary, and lake waters.
