S411 CIS_EastCoast ice chart quicklooks

The ice chart previews are made with a short python script. The scripts are running independently from the S411 production, therefore previews may be older than the S411 data itself. The standard S411/WMO portrayal is used for concentration and stage of development.The navigational portrayal is based on the POLARIS system. For each individual ice class the colors indicate:

ligth green
easy ice conditions (RIO>10)
light ice conditions (10>RIO>5)
normal ice operation (5>RIO>0)
elevated operational risk (0>RIO>-10)
special consideration (normally No-Go) (RIO<-10)
Clicking in the small preview opens a larger version (use the back button to return to this page).
