Since this is apparently your first visit to this new site version, here are some hints...
The whole site has been redesigned. Only the independent tools were kept in their original look (eg: wiki, pictures,...).
Menu is now dynamically invoked: You can make it appear by hovering or clicking on the top left icon.
When looking at results maps, the calendar could be made visible by cliking the NE arrowicon; the SW arrowicon makes it disapear.
Monitoring charts period could be changed by clicking on the arows at the bottom of the page, text will tell you which period you are looking for.
This pop-up, won't bother you again, unless you erase its cookie (Specat-demo).
Click anywhere to make this pop-up disapear.
Enjoy your browsing, and don't forget to report any bug.
