In this article, difference maps created with Giovanni and NASA Panoply demonstrate how emissions of NO2 from wildfires in August 2019 were substantially higher than in August 2018, based on comparison to a 10-year mean for the region. NO2 data from the Ozone Measuring Instrument (OMI) was used for this comparison. An image created with Giovanni of average NO2 concentrations over the Amazon Basin in August 2019 is shown below.
