What to know about Mapping wildfire risk across the US, day by day

Scientists at the NSF National Center for Atmospheric Research have developed real-time maps that track vegetation moisture levels across North America to assess wildfire risk. The system utilizes weather models, satellite data, and machine learning to provide high-resolution updates on different types of plant fuels.

What happened

Mapping wildfire risk across the US, day by day Gaby Clark Scientific Editor Andrew Zinin Chief Editor Wildfires can spread fastest when they tear through areas of dry vegetation.

Why it matters

In contrast, vegetation that contains a lot of moisture can slow a wildfire's advance and give firefighting crews precious time to contain the blaze.

Common ground

Because dryness is such a critical driver of wildfires, a team of scientists at the U.S.

Claim 3: “To create the maps, a team of NSF NCAR fire experts, meteorologists and machine learning specialists drew on advanced weather models and observations of land cover and the atmosphere, including data from two NASA and NOAA satellite instruments: the polar-orbiting Visible Infrared Imaging Radiometer Suites, or VIIRS, and the geostationary Advanced Baseline Imager, or ABI.”

SINGLE SOURCE

While web results confirm the existence of VIIRS and ABI satellites and their use by NOAA/NASA, the specific combination of these tools used by the NSF NCAR team for this specific map is not corroborated by a second independent source in the provided evidence.
