Canadian Arctic Composite Disclaimer

Data on this composite image ranges in time from that given by the header to several hours old.

This composite starts fresh each day with the data from the first pass of day placed on the map. The first pass typically covers the easterly portion of the map. Through the day new data replaces sections of old data or fits in areas not previously covered. The time between the newest and oldest data may by 4-6 hours. By midday most of the map is covered and some areas have had old data replaced several times. By end of day all but sections of east Greenland have data.
