Air Pressure During Three Blizzards (MERRA-2)

MERRA2 Reanalysis – Mean Sea Level Pressure (Select Events)
atmosphere NASA VEDA COG
In plain English

What it measures. Maps of sea-level air pressure during three selected blizzard events, which reveals the strength and location of each storm's low-pressure center.

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

How & where you'd use it. Helps analysts pinpoint and gauge the intensity of the low-pressure systems driving these blizzards.
