Air Temperatures During Three Blizzards (MERRA-2)

MERRA2 Reanalysis – 2 Meter Temperature (Select Events)
atmosphere NASA VEDA COG
In plain English

What it measures. Maps of near-surface air temperature (about 2 meters above the ground) 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. Helps analysts study how cold these blizzards were and where freezing conditions spread.
