What is Naiad ?
Naiad is a system designed by the Center for Satellite Exploitation and Research (CERSAT) at Ifremer to search, visualize and extract relevant data from massive archives.
Using Naiad web interface
To run Naiad interface properly, you need at least the following browser versions :
- Mozilla Firefox > 2.x
- Internet Explorer 7.x
- Opera 9.x
- Iceweasel > 2.x
- Icecat > 2.x
The dataminer requires a screen resolution of 1024 by 768 or above to operate properly.

Access to O&SI SAF METOP wind and sea surface temperature data
METOP is the first of a new series of weather satellites operated by EUMETSAT. It embeds two relevant sensors for oceanagraphy : a scatterometer for sea surface wind and sea ice measurement, and an infrared radiometer allowing to retrieve the sea surface temperature at high resolution and over the whole oceans. The ocean data for METOP are produced by the O&SI SAF and these data are now accessible for extraction and visualization through Naiad portal.
17 years of storms and hurricanes tracked by scatterometers
Scatterometers are satellite embedded microwave radar specially designed to measure the sea surface wind speed and direction under all weather and cloud conditions. Since the launch of ERS-1 in 1991, sea surface winds have been continuously measured at global scale thanks to an uninterrupted series of missions such as ERS-2; ADEOS-1, QuikSCAT, ADEOS-2 and now METOP-A. We have scanned the complete archive of some of these missions (currently ERS-1, ERS-2, QuikSCAT and METOP-A) in order to identify and register a complete index of all storm observations. Users with a focus on extreme wind events can now access through Naiad this extensive catalogue which spans over more than 17 years. This work was supported by ESA, as part of the enhancement of the legacy of ERS missions.
