   EarthVectorType is the VisAD data type for 2-D and 3-D wind
   or current vectors in Units convertable with meter / second
   whose first component is parallel to latitude lines, positive
   east, and whose second component is parallel to longitude lines,
   positive north.  It assumes vertical coordinates transform
   nearly flat, so the optional third vertical wind component
   does not transform.
