Newsletter #7 - January 6th, 2025
OSI SAF's best wishes for 2025
Dear users, colleagues and partners,

As a new year begins, the OSI SAF team wants to wish you all the best for 2025! May this year be a successfull one for satellite monitoring of the ocean.

To start the year well, please find here our seventh newsletter! In it you'll find news about the work done by visiting scientists with our Sea Surface Temperature and our Sea Ice teams. We present you as well a use case of our Sea Surface Temperature products for Norway's coastal ocean forecasting model.

If you're looking for a good resolution easy to keep, you could send feedback to your dear satellite open data provider: you could answer our little survey (see below in the What's Up section). It takes only 5 minutes, and it will help us greatly to provide you with the best possible service.

Supporting Marine Earth Observation Applications
Supporting Marine Earth Observation Applications, 24 February - 21 March 2025
In 2025, EUMETSAT will organise a new iteration of the "Supporting Marine Earth Observation Applications (SMA)" course. This completely online course is organised in partnership by the EUMETSAT Copernicus marine training service, OSI SAF and the university of Hull.

Estimating the uncertainty of Sea-Ice area and Sea-Ice extent from satellite retrievals

In the context of the OSI SAF Visiting Scientist Program, Andreas Wernecke from the University of Hamburg, Germany, worked on assigning realistic uncertainties to integrated quantities such as the monthly mean Sea-Ice Extent and Sea-Ice Area computed from maps of Sea-Ice Concentration. Check this story to learn more.

Towards an improved Sea Surface Temperature Climate Data Record from the MeteoSat Second Generation mission (2004-2023)

In the context of the OSI SAF Visiting Scientist Program, Marouan Bouali from ORBTY Ltda., São José dos Campos, Brazil, worked on several areas of improvement for an upcoming Sea Surface Temperature Climate Data Record. Additionally to validate the temporal stability of MSG-1/MSG-2, he managed to produced improved climatologies of SST and got promising results in level SST retrieval using the multidimensional Dynamics Data Fusion System.

Assimilation of Sea Surface Temperature by MET Norway's coastal ocean forecasting model Norkyst

The Norwegian Meteorological Institute (MET Norway) and the Norwegian Institute of Marine Research (IMR) have developed an ocean forecasting model specifically for the Norwegian coastal and shelf seas, called Norkyst. This model enables MET Norway to provide forecasts such as Sea Surface Temperature (SST) and ocean currents, which are crucial for oil spill response, search and rescue operations, and plankton dispersion tracking. Norkyst assimilates near real-time SST products from OSI SAF catalogue to enhance its forecasting capabilities.

What's up ?

We need you!

We provide you our data on an open and cost-free base. The downside is that we don't really know much about you, nor about how you use our products...
As we turn to 2025, we have taken the good resolution to remediate this, and we'd love to hear from you!
If you haven't answer it yet, please take 5 minutes to answer this short survey, it will help us keep providing you with the best possible service.

Stay tuned!

Our WIND team is working hard. Oceansat-3 Winds have been released as operational products on 31/10/2024. You can access both the 25km and 50km resolution on our FTP server, on EUMETCast and in the Eumetsat Data Center.
Together with the operational release of Oceansat-3 product, the HY-2B, HY-2C, and HY-2D wind products has been slightly upgraded in order to harmonise all Ku-band near real time products.

Save the date !

OSI SAF will take part to the "Supporting Marine Earth Observation Applications (SMA)" online course (24 February to 27 March 2025). Application are open until the 24 January 2025.

OSI SAF will be represented at the International SST users' symposium & GHRSST science team meeting (16 to 20 june 2025). Come and meet members of our team there!

OSI SAF in video!

We have been launching a serie of short interviews to present you who is working with us. Here are the videos released so far.

 

On 10/09/2024, we hold a webinar abbout our Sea Ice Climate Records, within the frame of EUMETSAT short courses. A recorded version of the webinar is now available on our youtube account :
