Wow, watch this! A big-picture look at Sandy, what made it so big, and what it means:
Owen Kelley, a research scientist at NASA Goddard, works with data from the TRMM satellite to image the insides of storms. TRMM looked into the eye of Sandy the day before it made landfall and saw something surprising. Satellites also took snapshots of Sandy. J. Marshall Shepherd, president-elect of the American Meteorological Society and the director of the Atmospheric Sciences Program at the University of Georgia, explains some of Sandy’s unusual features.
