Wind Speeds During Three Blizzards (MERRA-2)

MERRA2 Reanalysis – 10 Meter Wind (Select Events)
atmosphere NASA VEDA COG
In plain English

What it measures. Maps of wind speed near ground level (about 10 meters up) during three selected blizzard events.

How it's made. Drawn from MERRA-2, NASA's global weather reanalysis that reconstructs past atmospheric conditions.

How & where you'd use it. Lets analysts reconstruct how strong the winds were during these blizzards to understand their severity.
