Volcanicashforecast

NAME

Volcanicashforecast - Norwegian national volcanic ash products including forecast

DESCRIPTION

This service offers links to the Norwegian national ash products for aviation in case of volcanic ash in the atmosphere near to Norway. The products include volcanic ash forecast images, satellite images and a report with further information. Results of this service can be seen on https://ippc.no or https://volcanicashtest.met.no during an volcanic eruption in Northern Europe.

NOTE

This is a specialized product for IPPC and is not very understandable or usable for others. As such we do not offer any support for this version of the product. We hope soon to be able to make a new version which is more suited for general use.
