Summary
Abstract: ABSTRACT: OSTM/JASON-2 is a follow-on mission continuing the TOPEX/Poseidon and Jason-1, and is designed to ensure continuity of high quality measurements for ocean science and to provide operational products for assimilation and forecasting applications. The Jason-2 satellite was launched on 20 June 2008 and reached its nominal repetitive orbit on 4 July 2008. The level-2 X-GDR are available as 3 ... View entire text

Purpose: PURPOSE: To ensure operational continuity for the collection and distribution of high-resolution data on ocean currents and their variations, as well as sea surface height measurements. High-precision ocean altimetry measures the distance between a satellite and the ocean surface to within a few centimeters. Accurate observations of variations in sea surface height (ocean topography) provide scientists with information about the speed and direction of ocean currents and heat stored in the ocean. This information, in turn, reveals global climate variations.

Description: The NODC Ocean Archive System is used to search and retrieve originator datasets and metadata from the NODC archives. Note: The Ocean Archive System searches original datasets as they were submitted to the NODC, not individual points or profiles. Users who wish to search and retrieve ocean profiles or objectively analyzed fields may search through NODC's WODselect (World Ocean Database Select and Search system). Users having trouble finding a particular data set may e-mail the NODC at NODC.Services@noaa.gov, or call at 301-713-3277.
