type: Dataset
description: 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 wind pattern at the volcano, at 0-5 km elevation. Plots are in both jpg and pdf format.
