On Thursday, April 28, 2016, at approximately 8:30 a.m., a planned system fail-over test will result in delayed or missing data on the GOES, SPSD and OSPO web sites. Please see the outage message, which indicates that the duration is approximately 5.5 hours, and watch for additional information.

(OSTM) - Jason 2 Overview

The Ocean Surface Topography Mission (OSTM) is a joint effort by four organizations to measure sea surface height by using a radar altimeter mounted on a low-earth orbiting satellite called Jason-2. The four mission participants are:

* National Oceanic and Atmospheric Administration (NOAA)
* National Aeronautics and Space Administration (NASA)
* France’s Centre National d’Etudes Spatiales (CNES)
* European Meteorological Satellite Organisation (EUMETSAT)

The Jason-2 satellite mission launched successfully on June 20, 2008.

This satellite altimetry mission provides sea surface heights for determining ocean circulation, climate change and sea-level rise. The Jason-2 satellite is the follow-on to the TOPEX/Poseidon and Jason-1 satellites. The research satellites, TOPEX/POSEIDON and Jason-1, have been instrumental in meeting NOAA’s operational need for sea surface height measurements necessary for ocean modeling, forecasting El Niño/La Niña events, and hurricane intensity prediction.

Under the OSTM program NOAA provides support from its satellite ground segment capabilities for management of the Jason-2 Satellite flight operations during its routine operational phases and acquires, produces, and distributes geophysical data in a manner beneficial to all interested users.
