NASA releases satellite imagery of 1200+ mile smoke trail from California wildfires

On August 20, NASA released Terra satellite imry of plumes of smokes from California Fires. In a press release, NASA shared an im that depicted 1200+ Mile trail of smokes plaguing California wildfires region that dispersed in wind creating a blanket of haze. NASA wrote that its team captured unique im using an application that could calculate almost 1,214 miles rast to southwest trail of fire within app. 

“Fire is devastating, and effects of smoke on humans can also be devastating.  smoke released by any of fire forest, brush, crop, structure, tires, waste, or wood-burning is a mixture of particles and chemicals produced by incomplete burning of carbon-containing materials,” NASA wrote, describing devastating scene. It ded that hazardous plumes consisted of carbon moxide, carbon dioxide, and particulate matter, and toxic chemicals, including aldehydes, acid gases, sulfur dioxide, nitrogen oxides, polycyclic aromatic hydrocarbons (PAHs), benzene, toluene, styrene, metals, and dioxins, among ors. ding, that wildfires depleted availability of oxygen in environment as well as soared temperature, NASA said individuals in region were vised to avoid exposure to fires.

Individuals are vised to limit ir physical exertion if exposure to high levels of smoke cant be avoided. Individuals with cardiovascular or respiratory conditions (e.g., asthma), fetuses, infants, young children, and elderly may be more vulnerable to health effects of smoke exposure, NASA wrote in press release, warning population residing in vicinity of wildfires. 

Highlighting different toxic component’s constitution in satellite im using pointers and different colours, NASA indicated on its worldwide view site, "Aerosol Optical Depth (AOD) (or Aerosol Optical Thickness) indicates level at which particles in air (aerosols) prevent light from traveling through atmosphere.” Furr, it explained that aerosols scattered and absorbed incoming sunlight which dipped visibility on ground. “An AOD of less than 0.1 is “clean” (lightest yellow) - characteristic of clear blue sky, bright sun, and maximum visibility,” NASA elaborated, in context to im.

Smoke traced out into Pacific Ocean

“As AOD increases to 0.5, 1.0, and greater than 3.0, aerosols become so dense that sun is obscured ranging from yellow to dark red on scale,” it furr explained. In im, it could be seen that several regions in Los Angeles, Las Vegas, parts of San Francisco and into Idaho, were blanketed with smoke plumes. A trail of thick smoke traced out into Pacific Ocean. NASA's Earth Observing System Data and Information System (EOSDIS) Worldview application has earlier listed at least 700 global, full-resolution satellite imry of global events, including wildfires, detected by its rmal bands.
