visualization of total precipitable water over U.S. mid-2004
This visualization shows the development of the severe President's Day 1979 snow storm. The color contours are the sea level pressure (hPa), the color wind barbs are the surface layer winds (m/s values are colored according to the right side color bar), and total cloud fraction is shaded from black (no cloud) to white (complete cloud cover). This is generated from MERRA data currently available at the GES DISC.
