Satellites may be a more accurate way to track smog-producing ammonia.<\/p>\n

Its notoriously tricky to pinpoint accurate numbers for ammonia gas emissions from sources such as animal feedlots and fertilizer plants. But new maps, generated from infrared radiation measurements gathered by satellites, reveal global ammonia hot spots<\/a> in greater detail than before. The new data suggest that previous estimates underestimate the magnitude of these emissions, researchers report December 5 in Nature<\/em>.<\/p>\n

In the atmosphere, ammonia, which contains nitrogen, can help form tiny particles that worsen air quality and harm human health. The research could help keep tabs on whos emitting how much, to make sure that factories and farms are meeting environmental standards.<\/p>\n

Emissions are usually estimated by adding up output from individual known sources of activity, but those calculations are only as good as the data that go into them. Ammonia sticks around only hours to a few days in the atmosphere, so on-the-ground measurements vary a lot even in the same place, says coauthor Martin Van Damme, an atmospheric scientist at the Universit\u00e9 Libre de Bruxelles in Belgium.<\/p>\n

\u201cTheres so much uncertainty in ammonia emissions,\u201d says Daven Henze, a mechanical engineer at the University of Colorado Boulder who wasnt part of the research. Other scientists, including his research group, have estimated ammonia releases using satellite data before. But these new maps rely on a more detailed dataset and have substantially better resolution, Henze says \u2014 fine enough that the study authors were able to link areas of high emissions to specific factories or farms.<\/p>\n

Satellite data can help scientists map ammonia emissions around the world. This map shows average ammonia release over a nine-year period, with darker red corresponding to higher emissions. Scientists are able from the data to pinpoint sites releasing especially high levels of the smog-producing gas, including West Africa, northern India and areas around Beijing.<\/p>\n

The new maps show 248 nitrogen emission hot spots across the globe at a resolution of about a kilometer. Eighty-three of those hot spots arose from agricultural activity that involved high numbers of cows, pigs and chickens, such as a site in Colorado that overlapped on satellite imagery maps with two big cattle feedlots. Ammonia emissions from feedlots come largely from livestock waste. Another 158 sites were affected by industrial emissions \u2014 mostly from sites that produced ammonia-based fertilizer, such as in Marvdasht, Iran. Six hot spots couldnt be pinned to specific activity.<\/p>\n

Ammonia is also emitted naturally, from volcanoes or seabird colonies. But most of those sources were too weak or not concentrated enough to show up as hot spots in the data. Lake Natron in Tanzania is the one exception \u2014 its mud flats show up as an ammonia-releasing hot spot, perhaps due to decaying algae. But its not clear why other lakes with similar mud flats didnt. Some natural sources may have gone undetected because of where they were located \u2014 in places with heavy cloud cover that obscured the data, or where turbulent air dissipated ammonia especially quickly, Van Damme suggests.<\/p>\n

Some areas with particularly high overall ammonia emissions from biomass burning or fertilizer, such as West Africa and the Indus Valley in Pakistan and northern India, didnt reveal specific hot spots, either, the researchers report.<\/p>\n
