Lightning Ignition Efficiency: (August 2002) The
lightning ignition efficiency algorithm has been corrected due to
discovery of an error. The resulting maps reflect higher lightning
efficiency than previously.
NDVI Reprocessing: (August 2002) In March of 2001,
the EROS Data Center began a year-long effort to re-process raw
NDVI data with new algorithms to improve correction for atmospheric
moisture (not clouds). Generally this increased the observed NDVI
over past years' values. This reprocessing effort is complete and
historical GIF and data images are in preparation.
WFAS Redesign: (June 2002) The WFAS site has been
redesigned to provide easier access to products. Archives are
accessible by calendar. Comparisons between years can be displayed.
Animation of a sequence of images can be viewed.
Alaska: (June 2002) The Alaska Fire Service uses
the Canadian Fire Danger Rating System to monitor fire potential in
the Alaskan Interior. Some coastal Forest Service locations report
into WIMS on an irregular basis. Access to Alaska fire potential is
available at: http://fire.ak.blm.gov/. Then click on "Maps
and Imaging."
