• A Beautiful Yet Grim Map Shows How Wildfire Smoke Spreads

    Now, in the map menu, click on “Vertically Integrated Smoke.” Instead of measuring smoke around 8 meters off the ground, it’s modeling what a 25-kilometer-high column of air looks like in a given place in the US. (Think of it as the smoke that you can see in the sky, versus the near surface smoke being the stuff you’re actually breathing.) As you can see, on this scale, smoke now covers most of the country.

    To map this out, HRRR considers the infrared intensity of those fires and projects how much smoke a fire is producing. That smoke starts off in the eddies of what atmospheric scientists call the boundary layer. “It’s the layer through which you feel the bumps when you land in an airplane in the late afternoon anywhere in the country,” says Benjamin. “But then some of that air gets mixed further up above the boundary layer,

    What do the Philippines, Indonesia, and India have in common?

    All three nations have seen a massive surge in COVID-19 cases in the recent weeks.

    Some fear that the number of cases will only continue to rise due to the large population in all three nations. India is home to 1.4 billion people, while Indonesia and the Philippines have 267.7 million and 106.7 million people respectively.

    India is now third, after the U.S. and Brazil when it comes to total number of cases. It’s also the highest Asian nation with close to 3.7 million of its people infected. Looking at stats, it appears that the number of cases are only expected to climb after 78,512 cases were recorded on August 31, 2020 alone, following the reopening of its economy.
