NASA scientists recently developed a model that investigates different climate factors that prompt the development and spread of fires. The Global Fire Weather Database (GFWED) represents nearby winds, temperatures, and humidity, while likewise being the first fire forecast model to incorporate satellite-based precipitation estimations.
Foreseeing the force of flames is vital on the grounds that smoke can influence air quality and increment the measure of greenhouse gases in the climate. The model compiles and examines different informational indexes and creates a rating that demonstrates how likely and intense fire may move toward becoming in a specific zone.
It is a similar sort of rating that numerous firefighting organizations use in their day– to– day operations. historical information is accessible to comprehend the climate conditions under which fires have happened before, and near–real-time information is accessible to check current fire risk.
Robert Field, creator of GFWED and a climate scientist at NASA’s Goddard Institute for Space Studies said, “Rather than look at the individual weather components, we look at their comprehensive effect. It’s not just one factor that causes a fire to start or spread.”
“For instance, if a region has not received normal precipitation for weeks or months, the vegetation might be drier and more prone to catching fire. Then if it gets windy, a fire could spread more quickly.”
“Across much of the world, tracking fires and smoke using NASA satellite data is the only way to get a consistent picture of fire activity, and our fire weather data helps us to understand the causes. That will help us to understand how fire activity might change and allows us to think ahead for different climate scenarios.”
GFWED consolidates meteorological information from a few sources. Temperature, relative humidity, and wind speeds originate from NASA’s MERRA2 dataset of the Global Modeling and Assimilation Office (GMAO). Precipitation information originates from ground-based rain gauges and from the Integrated Multi-Satellite Retrievals (IMERG), a result of the Global Precipitation Measurement mission.
Utilizing the GMAO weather forecasts, GFWED likewise incorporates experimental 8-day global forecasts of fire risk.
Scientists noted that the model has been especially helpful in Indonesia, which tends to have an intense fire season during El Niño years. A field has been working with the Indonesian Agency for Meteorology, Climatology, and Geophysics and the Ministry of Environment and Forestry to improve that country’s fire danger maps.
