We received a message from Dispatch informing us of an ozone area containing 0.25 PPM from FL360 to FL500 along our route of flight. Neither the Captain nor I realized the relevance of the ozone concentration and did not descend from FL360. We didn't find any useful information in the FOM regarding our course of action. An hour and a half later we received another message from Dispatch informing us that a report was being generated on our flight because we had remained at FL360 and to call Dispatch if we needed any further details.
A B757 received an Ozone Alert from Dispatch on a North Atlantic Track but had no guidance about what action should be taken.
