title: X-TRACK, Along track Sea Level Anomalies (2017_02)

description: X-TRACK, is a regional altimeter products for coastal applications. It has been developed in order to optimize the completeness and the accuracy of the sea surface height information derived from satellite altimetry in coastal ocean areas. 1hz alongtrack SLA are available in 23 regions for different altimetric missions (Topex, Jason-1&2, Geosat, Ers2, Envisat). SLA is computed on a reference track. X-TRACK SLA files hold alongtrack SLA data together with MSSH, FES2012 tide, Dynamic Atmospheric Corrections and distance to coast parameters. Users can both retrieve filtered and non-filtered data.
