Furthermore, the current use of\naltimeter and scatterometer data to support these services is described.<\/p>\n\n\n\n<p>The\nreport describes requirements with respect to current and new radar altimeter\ndata which should be met by future providers of satellite data to ensure\nthat data can be assimilated in an optimal manner in the wind and wave models.\nThe requirements concern timeliness, maximum footprint and spatial coverage. Opportunities\nare identified if altimeter data would be available with higher ground track\nspacing and higher spatial resolution for wind and wave retrievals near shores\nand estuaries.<\/p>\n\n\n\n<p>Orbit configuration of a multiple of small altimeter\nsatellites is not straightforward, because the choice of repeat frequency and\nspatial coverage is a trade-off, depending on application.<\/p>\n\n\n\n<p>Furthermore, Hermess identifies applications in\ncoastal water as a promising new market for an innovative altimeter system,\nalthough anomalies like wave-seabed\ninteraction and wave breaking in the surf zone makes processing a challenging\ntask. Hermess adds several considerations to keep in mind when designing a\nmultiple altimeter constellation.<\/p>\n\n\n\n<p>For NL-RIA knowledge network partners, the Hermess report\nis available in the Resources area on our website.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Dutch company Hermess delivered the report User needs on radar altimetry data for offshore, oceanographic and maritime applications for the NL-RIA knowledge network.
