Layers:
Wildfire Automated Biomass Burning Algorithm (WF-ABBA)
The SSD product is a reformatted version of the North American product available on the CIMSS website. The reformatting of the WF-ABBA product consists of removing the lowest probability fires (category 5), as validation at CIMSS has shown that many of the low possibility fires are not fires. The fields fire size and temperature have been removed as they are very rough estimates of the average instantaneous sub-pixel fire(s) size and temperature, and are not meant to be used for wildfire diagnosis. The header is simplified and the table is put into comma-delimited form so that it can be easily read into a Geographic Information System (GIS) as table data. Each fire is described by a single line, specifying longitude, latitude, 4 micron (channel 2) temperature, 11 micron (channel 4) temperature, ecosystem category, and a fire flag.

Global Land Cover Characteristics Data Base
The U.S. Geological Survey's (USGS) Earth Resources Observation System (EROS) Data Center, the University of Nebraska-Lincoln (UNL) and the Joint Research Centre of the European Commission have generated a 1-km resolution global land cover characteristics data base for use in a wide range of environmental research and modeling applications (Loveland and others, 2000). The land cover characterization effort is part of the National Aeronautics and Space Administration (NASA) Earth Observing System Pathfinder Program and the International Geosphere-Biosphere Programme-Data and Information System focus 1 activity.
The data set is derived from 1-km Advanced Very High Resolution Radiometer (AVHRR) data spanning a 12-month period (April 1992-March 1993) and is based on a flexible data base structure and seasonal land cover regions concepts. Seasonal land cover regions provide a framework for presenting the temporal and spatial patterns of vegetation in the database. The regions are composed of relatively homogeneous land cover associations (for example, similar floristic and physiognomic characteristics) which exhibit distinctive phenology (that is, onset, peak, and seasonal duration of greenness), and have common levels of primary production.

Hazard Mapping System Fire and Smoke Product
The HMS is an interactive processing system that allows the trained satellite analysts in the Satellite Analysis Branch (SAB), within the Satellite Services Division (SSD), to manually integrate data from various automated fire detection algorithms with GOES and polar (Advanced Very High Resolution Radiometer (AVHRR), Moderate Resolution Imaging Spectroradiometer Fire Algorithm (MODIS) and Defense Meteorological Satellite Program/Operational Linescan System (DMSP/OLS)) images. The result is a quality controlled display of the locations of fires and significant smoke plumes detected by meteorological satellites.
