NASA on Amazon Fires

August 27, 2019

NASA Earth Observatory:

On August 19, 2019, the MODIS instrument on NASA’s Terra satellite captured a natural-color image (top of the page) that shows fires burning in the vicinity of Novo Progresso in the Brazilian state of Pará. The town is located along BR-163, a straight north-south highway that connects farmers in the southern Amazon with an ocean-going port on the Amazon river in Santarém. Pasture and croplands are clustered around the highway in ordered, rectangular plots. To the west of the highway, winding roads connect a series of small-scale mines that extend deep into the rainforest.

With the fire season in the Amazon approaching its midpoint, scientists using NASA satellites to track fire activity have confirmed an increase in the number and intensity of fires in the Brazilian Amazon in 2019, making it the most active fire year in that region since 2010.


Fire activity in the Amazon varies considerably from year-to-year and month-to-month, driven by changes in economic conditions and climate. August 2019 stands out because it has brought a noticeable increase in large, intense, and persistent fires burning along major roads in the central Brazilian Amazon, explained Douglas Morton, chief of the Biospheric Sciences Laboratory at NASA’s Goddard Space Flight Center. While drought has played a large role in exacerbating fires in the past, the timing and location of fire detections early in the 2019 dry season are more consistent with land clearing than with regional drought.


“Satellites are often the first to detect fires burning in remote regions of the Amazon,” Morton said. NASA’s primary tool for fire detections since 2002 has been the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on the Terra and Aqua satellites.
At this point in the fire season, MODIS active fire detections in 2019 are higher across the Brazilian Amazon than in any year since 2010. The state of Amazonas is on track for record fire activity in 2019.


Morton noted that 2019 fire activity statistics distributed by NASA and Brazil’s Instituto Nacional de Pesquisas Espaciais (INPE) are in agreement. “INPE also uses active fire data from NASA’s MODIS sensors to monitor fire activity in the Brazilian Amazon,” Morton said. “As a result, NASA and INPE have the same estimates of chanes in recent fire activity. MODIS detections are higher in 2019 than at this time last year in all seven states that comprise the Brazilian Amazon.”


MODIS fire detections are analyzed by the Global Fire Emissions Database (GFED) project, which includes Morton and colleagues from NASA Goddard, the University of California, Irvine, and Vrije Universiteit Amsterdam. Over the years, the GFED team has processed 17 years of NASA satellite data to better understand the role of fire for changes in the Earth system. Their analysis of the southern Amazon includes parts of Brazil, Peru, and Bolivia that typically see fires between July and October. Their data plots are available online here.


The map above shows active fire detections in Brazil as observed by Terra and Aqua MODIS between August 15-22, 2019. The locations of the fires, shown in orange, have been overlain on nighttime imagery acquired by VIIRS. In these data, cities and towns appear white; forested areas appear black; and tropical savannas and woodland (known in Brazil as Cerrado) appear gray. Note that fire detections in the Brazilian states of Pará and Amazonas are concentrated in bands along the highways BR-163 and BR-230.

    Hmmmm. So tell me again why we’re having all these fires in the Amazon? It’s because small farmers are burning off the forest so they can plant soybeans?
    And they are planting soybeans because China wants to buy them? And China wants to buy Brazilian soybeans because they have cut way back on their purchase of U.S. soybeans? Because of Trump’s trade war?

    So, it’s obvious—-it’s all the fault of Nancy Pelosi, “The Squad’, Democrats in general, and the Fake News Media.

    Once the highway was built through the rainforest, it wasn’t going to be long before it got eaten away.
