> NEW! 31/10/2018 Special diagnostic for the Route du Rhum sailing race!

> EXCLUSIVE! This website is the first one to map live data from more than 100 sensors at sea (North Atlantic)


Route du Rhum⇩  North Atlantic⇩  Europe⇩  USA/Canada⇩ 


Added value of the MeteOceanOnline sea-level pressure reconstruction (near real time) over GFS real-time solutions (short-term forecasts), computed as the innovation towards observations. The control solution is a 4DVAR analysis (ARPEGE, delayed availability). This test is based on stations of the North Atlantic ocean away from the Greenland and Newfoundland neighborhoods. Quality of the MOO reconstruction depends on a total number of sensors at sea large enough.

NEW! 03/10/2018 Added value of MeteOceanOnline temperature reconstruction in Europe ("Europe 1" domain)

Diagnostics are value-added products mainly based on the real-time observation data.
Data is high quality from the real-time global observation network where most of the spurious records have been filtered out.
Data density and diagnosis quality of each date increase with time due to regular updates.
