On Tuesday, September 5, residents of the Pacific Northwest watched from the sky like snow, the ash falls. When he reached the ground, fires blazing in the Western United States and in Canada, again raised it with the smoke high into the atmosphere. Part of the aerosols reached most of Europe.
Intercontinental journey of smoke shown on the maps. Data were obtained from 4 to 7 September with an instrument Ozone Mapping Profiler Suite (OMPS) on the Suomi NPP satellite. On the maps of the relative concentration of aerosols: low concentrations marked with light-yellow, tall — dark-brown.
During all days high concentrations of aerosols occurred over the sources in the North-West Pacific ocean. But the prevailing winds carried away the high-rise smoke aerosols and transferred them to the East across the continent. Monday, September 4, smoke spread to the South-West USA, September 5, reached Newfoundland, and on 6 September the cloud of smoke could be seen clearly in the middle of the Atlantic ocean.
“As you can see, a cloud of smoke 6 Sep is part of a long stream of smoke, flew across the Atlantic”, — said Colin Seftor, an employee of the space flight Center of NASA Goddard.
Thursday, September 7, the smoke arrived in Ireland, Britain and Northern France. These aerosols are high in the atmosphere, so they do not pose a serious threat to air quality, land and human health. But this case clearly demonstrates how events in one continent can affect other parts of the world.
“It’s not uncommon for smoke from fires in North America comes to Europe”, — says Sartor. However, he noted that the smoke, which reach Europe this year, more large, dense and stable. For example, smoke from fires in the United States in mid-August, hung over Europe for several days.
Forest fires lasted long before was compiled with these cards, and continue to burn even now. An image in natural color shows the smoke passing through the Northern Middle West September 13.
The picture was taken using the Spectroradiometer MODIS on the NASA satellite “Aqua”. This year record heat in some parts of the Western United States was named as a possible cause of widespread fire activity that was somewhat surprising given the wet winter and spring in the region.
