Global Emissions Inventory Activity
Organization:  GEIA Steering Committtee 
Metadata:     
Description: The Global Emissions Inventory Activity (GEIA) was created in 1990 to develop and distribute global emissions inventories of gases and aerosols emitted into the atmosphere from natural and anthropogenic (human-caused) sources. The long-term goal is to develop inventories of all trace species that are involved in global atmospheric chemistry. GEIA's mission is to provide high quality data for timely, relevant assessments. The requirements for a data set to be accepted as a GEIA data base include substantial peer review as reflected by acceptance for journal publication and agreement among the individual GEIA project teams. Current, data sets include: Nitrogen Oxides in Soils, NOX Lightning data, Volcanic Sulfur EmissionsAmmonia, Black Carbon (Black Carbon from Fossil Fuel Combustion, Fossil Fuel & Biomass Burning Black Carbon); Carbon Dioxide (fossil fuels); Carbon Monoxide; Chlorofluorocarbons; Methane (Anthropogenic (preliminary), Natural); Nitrous Oxide;Nitrogen Oxides, Annual;Nitrogen Oxides, Seasonal;Reactive Chlorine Emissions; Sulfur Dioxide, Annual; Sulfur Dioxide, Seasonal and Volatile Organic Compounds (Anthropogenic: Non-Methane Volatile Organic Compounds, Natural)

Measured Fire Data Resources

GCVTC Fire Emissions Data
Organization:  CIRA
Metadata:     
Description:   As part of the Grad Canyon visibility Transport Commission process, a  special effort was undertaken by the USDA - Forest Service to develop emission estimates for prescribed fire and wildfires (i.e., wildland burning) in the western United States. Data include Prescribed Burning Emission Estimates including acres burned, fuel loading, and fuel consumption. This extensive data set was developed through surveys and represents 1989 conditions. The emission estimates cover prescribed fires on private, state, and federal lands; and Wildfire Emission Estimates acres burned, fuel loading, and fuel consumption for the emission calculations were obtained from the private, state, and federal land managers in the western United States. Since there is natural variability in wildfire emissions the wildland burning database contains emission estimates by fire event for 1986 through 1992 for the western United States. The monthly and daily wildfire emissions are displayed graphically on the CIRA/NPS web site. These emissions are fully described described in Emission Estimates for Assessing Visual Air Quality on the Colorado Plateau by Ronald J. Dickson, William R. Oliver, and Howard W. Balentine in J. Air & Waste Manage. Assoc. 47: 185-193.

Coarse-Scale Spatial Data for Fire and Fuel Management
Organization:  USDA Forest Service, Joint Fire Sciences Program (JFSP) 
Metadata:     
Description: This project involved mapping and characterization of historic natural fire regimes and current vegetation conditions, and development of an index of departure for use in national-level fire management planning. The concept of risk was defined as the 'risk of losing key components that define a system' or specifically, losses attributed to the occurrence or introduction of fire,either wildland or prescribed fire. Within that framework, we classify current conditions as a function of departure from historical natural conditions. These data integrate biophysical information and pre-existing remotely sensed products. We have incorporated disturbance and successional processes, including development of stylized successional pathways for unique combinations of historical fire regime and potential natural vegetation. These data are intended for national, programmatic and strategic planning, and will be used by federal land managers, states, and other non-governmental organizations in fire and fuel management planning, assessments of ecosystem health, and risk assessments.

Global Fire Monitoring Imagery 
Organization:  Earth Observatory, Goddard Space Flight Center, NASA
Metadata:     
Description:   The global fire monitoring web site provides recent satellite imagery and analysis of data about terrestrial fires and demonstration of future global fire monitoring capabilities. Imagery from several satellite systems including NOAA, DMSP, SeaWiFS, ERS, JERS, Landsat, SPOT and TRMM demonstrate the capability of satellite systems to monitor global fires and determine the total area of forests and grasslands burned each year and to estimate the amount of resulting emission products. The data will be used to develop better computer models and enhance scientists' abilities to predict how biomass burning will impact climate, the environment, and air quality. Data at the Earth Observatory Global Fire Monitoring site include 1 km AVHRR and 4 km TRMM observations.
