Wildfires around the world are increasing in frequency, size, and severity, including at the wildland-urban interface. These events pose threats to the ecosystems, processes, and lives within the areas they develop. The measurement of variables prior, during, and following fire events will become increasingly important as these events continue. This session focuses on new measurements of fire weather, wildfire, and the post-burn areas including observational strategies, new techniques, and recent results from field programs.
