40 Year (1961-2000) Climatology of the Haines Index for North America
The Haines Index is a measure of how readily atmospheric conditions roughly 1 to 3 km (0.5 to 2 miles) above the ground would support the development of a large or erratic plume dominated
wildfire. As part of a project funded by the US Forest Service and the Joint Fire Science Program, research scientists at Michigan State University, the Northern Research Station, and the Pacific Wildland Fire Sciences Laboratory have created this climatology of the Haines Index based on data from the years 1961 through 2000.
** All of the maps in the Haines Index Climatology were produced
using federal funding. They are in the public domain. **
