Northern Plains Dust and Haze, May 2022 Derecho

MODIS Aersol Optical Depth (AOD) for May 12, 2022
atmosphere NASA VEDA COG
In plain English

What it measures. Measures how much dust, smoke, and haze hung in the air over the Northern Plains during the daytime on May 12, 2022, when a powerful windstorm (derecho) swept through.

How it's made. Built from NASA's MODIS satellite instrument, which gauges how much sunlight airborne particles block (aerosol optical depth).

How & where you'd use it. Helps track air-quality hazards and visibility during severe wind and dust events.
