The air is full of tiny limpid and solid particles , collectively known as aerosol . They ’re produce by junk storms , volcanic eruptions , human action , and even the lifelike passing of the seasons . This amazing map expose where the aerosol can are .
NASA put this map of aerosol distributions together using the Moderate Resolution Imaging Spectroradiometer , or MODIS , on NASA ’s Terra and Aqua satellites . Let ’s let NASA tell us what we ’re look at :
This map testify the worldwide distribution of aerosol bomb in August 2010 , and the proportion of those aerosol that are large or small . Yellow areas are predominantly coarse particle , like detritus and ocean salt , while ruby areas are mainly fine aerosols from Mary Jane or pollution . Gray indicates expanse with no data . The brighter or more intense the color , the higher the concentration of aerosol container .
So why does one expanse have lots of bad particles , while another has a comparatively paltry amount of smaller particles ? NASA explains :
Yellow band - larger , harsh particles - around the Middle East , North Africa , and western North America likely indicate dust and sand storm as the northerly hemisphere reaches the driest time of year . The bright red expanse in Russia and much of South America reveal the vivid wildfire and some agrarian burn , which concur with hot summers and drouth in several region . The red patch in western Canada spring from summer wildfires , while China was likely grapple with a combination of firing , debris , and pollution events . It is undecipherable what was happening in westerly Africa .
