New Release of Daily Satellite Turbulent Fluxes
The surface turbulent fluxes estimated from satellite observations are reprocessed for QuikSCAT period October 1999 – November 2009 (Bentamy et al, 2013). They are calculated as daily turbulent air-sea fluxes over global oceans with a spatial resolution of 0.25° in longitude and latitude. The main improvements with respect to V2 version flux products (Bentamy et al, 2008) are related to the improvements of the specific air humidity estimation from radiometer…
Observing storm-generated swell from space
On the afternoon of the 5th January 2008, a team of adventurous surfers was able to ride huge waves at Cortes Bank spot, bringing back these impressive reports and pictures of some of the biggest waves ever surfed on this spot. But swells can be observed and followed also from space using the synthetic aperture radars such as the ASAR instrument onboard ENVISAT on a routine basis. We provide every…
Ocean colour and phytoplankton flora
A new Ocean Colour product is now available at CERSAT : Satellite-derived chlorophyll-a associated to the phytoplankton flora observed at coastal stations
Real-time time detection of a Karenia mikimotoi bloom from space in the Western English Channel in July 2010
Ifremer has been monitoring coastal waters from space for many years using SST, chlorophyll and turbidity levels derived from satellite observations, as a contribution to several European environmental monitoring frameworks. We are in particular committed to provide rapid alert in case of eutrophication or HAB (Harmful Algal Bloom) occurring in areas under our responsability. The exceptional bloom of karenia mikimotoi that took place in July 2010 in the Channel is…
REAPER reprocessing completed!
The full-mission reprocessing of the ESA ERS Radar Altimetry (RA) Level 2 data has been completed and the new data set is now available online to the ESA Earth Observation user community.
Record-breaking wave heights and periods in the North Atlantic
February 2011 was extremely stormy in the North Atlantic. A study just published in the Bulletin of American Meteorological Society (December 2012 issue) looks into the anatomy of a record-breaking monster: extra-tropical storm Quirin was caught blowing ocean waves up to significant heights of 20.1 m on February 14 in the middle of the Atlantic...  
Release of new global wind fields from Metop scatterometer
New gridded daily wind fields from Metop/ASCAT scatterometer retrievals are produced in near real-time over global ocean with a spatial resolution of 0.25°. They are in netCDF format and span from April 2007 to present.  
Reprocessing Daily QuikSCAT Surface Wind Fields
Gridded daily wind vector and wind stress fields, estimated over global ocean from QuikSCAT scatterometer (referred as DQSCAT) data, have been updated. Their spatial resolution is 0.25° in longitude and in latitude. They are produced from the new QuikSCAT wind retrievals indicated as QuikSCAT V3 (ftp://podaac.jpl.nasa.gov/OceanWinds/quikscat/preview/L2B12/v3/). Wind retrievals are provided over QuikSCAT swath at Wind Vector Cell (WVC) of 12.5km spatial resolution. The new scatterometer product is assumed improving wind…
Sea Surface Salinity measured from space for the first time !
 A new method was developed that combine C and X-band brightness temperature measurements over the ocean to retrieve for the first time salinity is from satellite microwave radiometer measurements It provides a mean for monitoring salinity in the Amazon plume and it is very encouraging for future L-band radiometry from space.  
The oil spills of Prestige tanker observed from space
On 13th November 2002, the tanker Prestige was wrecked off Galice (Spain) after its crew was rescued. This was the beginning of the third big oil slick in Galice history. This event was monitored from space by satellite-embedded high resolution microwave radars.
