Wildfire smoke is a mixture of hazardous air pollutants, such PM 2.5, NO 2, ozone, aromatic hydrocarbons, or lead. In addition to contaminating the air with toxic pollutants, wildfires also simultaneously impact the climate by releasing large quantities of carbon dioxide and other greenhouse gases into the atmosphere.
Wildfire is an essential process connecting terrestrial systems to the atmosphere and climate. As vegetation burns, it releases smoke, carbon, and other materials into the atmosphere. These fires also release nutrients into the soil and are an integral part of ecological succession, plant germination, and soil enhancement.

A wildfire is an unplanned fire that burns in a natural area such as a forest, grassland, or prairie. Wildfires are often caused by human activity or a natural phenomenon such as lightning, and they can happen at any time or anywhere. In 50% of wildfires recorded, it is not known how they started.
This section provides links to tools and applications relevant to analyzing and visualizing wildfire data referenced in this Data Pathfinder. NASA's Earth Science Data Systems (ESDS) Program maintains many more resources for data analysis that may be helpful. Explore the full list on the NASA Earthdata Data Tools page. AppEEARS

Wildfire season in the Pantanal generally begins in July and peaks in August and September. Low rainfall amounts have caused the wildfire season to start earlier than usual. The image on the left (A side) is a true-color corrected reflectance image overlaid with the VIIRS fires and thermal anomalies layer, with detected hotspots shown as red dots.
This wildfire occurred in 2007, and sampling took place in 2008-2011 and in 2017. Global Fire Atlas with Characteristics of Individual Fires, 2003-2016 The Global Fire Atlas is a global dataset that tracks the day-to-day dynamics of individual fires to determine the timing and location of ignitions, fire size, duration, daily expansion, fire line length, speed, and direction of spread.
The NASA data that Davies, Ichoku, Rasolohery, and many others use to track and study wildfire provide critical information they need to determine what blazes mean for African communities. Understanding the data can certainly be complex and nuanced at times, such as when viewing hundreds of tiny fire points on a world map.
