The NASA chart shows how natural disasters are affecting the speed of aerosols this week



The Earth experienced several forest fires, hurricanes and other natural disasters last week. As scientists observe and respond to these volatile climates, NASA provided insight into how such events affect even the smallest, often invisible matter particles that are omnipresent in the air.

On Friday, NASA released a map of the Earth showing the current ebb and flow of aerosols that are solid particles or airborne liquid droplets. Using a model called Goddard Earth Observing System Forward Processing, or GEOS FP, the space agency was able to improve the colorization of each particle type to reflect the aerosol velocity and presence as recorded on Thursday, August 23.

Instead of satellite data, the GEOS FP is a weather and climate model that uses mathematical equations to represent and calculate physical processes in the atmosphere that day. However, the NASA Earth Observation Center used some satellite inputs from MODIS (Moderate Resolution Imaging Spectroradiometer) sensors to track radiant power and simulate real-time conditions.

As NASA visualization showed, Thursday was eventful. The map shows black carbon particles in red, which NASA describes as aerosols released by fires or emissions from vehicles and factories. The red and orange swirls in North America reflect the forest fires that continue to rage across the west coast of the US and Canada. Meanwhile, hurricanes and tropical storms, such as those that hit Hawaii, South Korea and Japan, cause aerosols by sea spray, as can be seen from the concentrated light blue swirls. While these maps are visually striking, NASA reminded viewers of the violent situations that are some of the vortexes.

"Some of the events that appear in the visualization caused quite serious problems on the ground," the agency stated on its website. "On August 23, Hawaiians plunged into torrential rains and possibly heavy floods and mudslides as Hurricane Lane approached, with two tropical cyclones, Soulik and Cimaron, on the verge of whipping South Korea and Japan, and the plume of smoke over Central Africa is a seasonal phenomenon and mainly the product of farmers igniting numerous small fires to obtain crop and grazing land.Most of the smoke in North America came from large forest fires in Canada and the United States. "

Although aerosols are often not seen, People inhale millions of these omnipresent particles of matter, and their presence and patterns are of great importance to scientists because they monitor the behavior of forest fires and the presence of soot swarms. The Earth Observatory intends to routinely integrate these aerosol mappings into other models and weather mapping systems to better simulate real conditions in their deployment.
