Input data: | - Waves: Envisat, Jason-1, Jason-2, Jason-3, AltiKa and Sentinel-3A - Winds: Envisat, Jason-1, Jason-2, Jason-3 and Sentinel-3A - Last 2 days of IGDR data available for each satellite. A merged map is generated if a minimum of 2 missions are available. |
Processing: | - Smoothed and extrapolated by a Loess filter of 16° x 8° (gaps due to missing data are filled, signal is strongly smoothed). • Extrapolation is limited to 8°x4°, in order to avoid artificially filling areas without data. • A reduced bathymetry mask is applied: each point more than 2° from the sea is forced to default value. - If more than 30% of the points have default values, no map will be generated. - After September 14 2013, an extrapolation is made (see the details about the reprocessing) |
