This zip folder contains ASCII text files of vectors at the specified volcano at
12-hour intervals,
from January 1, 1990 through December 28, 2009.
The wind vectors are divided into five files, names by their elevation range above
sea level in the atmosphere: 00-05km.txt; 05-11km.txt; 11-16km.txt; 16-24km.txt;
and 24-30km.txt.
The zip folder also contains a subfolder "figures", with Wind rose plots of wind
direction and speed over
this time period. The plots are by season, and by elevation, given a total of 20
plots (4 seasons, 5
elevation ranges). A summary plot is also included which gives the year-round
