FIREXAQ: Insights into satellite- and fuel-based fire emissions
Abstract
Since the satellite era began, we have had the capability to view Earth and environmental phenomena including fires across landscapes from space. Through the use of these satellite data, we have the ability to estimate fire emissions for emissions inventories, air quality and health, and in chemical transport and climate models. However, there is a disconnect between ground-based and top-down estimates, and the reasons for these differences are not clear.
Using data and information from the NASA/NOAA FIREX-AQ (Fire Influence on Regional to Global Environments and Air Quality) airborne field campaign, we will quantify differences found in fire burning on the landscape and the view from space. This campaign sampled both natural and anthropogenic fires across the continental United States and was explicitly focused on fire emissions, air quality, and climate. The goal of this work is to: provide explanations for among-fire differences, with a focus on missing data; and to suggest viable solutions. First, we will briefly present the methodology used to estimate daily and 1-second emissions for each fire using ground- and satellite-based data. Then, we will compare and contrast the capability of current satellite-based products to track fire across landscapes and quantify fuels. Data and derived products considered include fire weather, FCCS, CDL, MODIS, VIIRS, GOES, Fire Radiative Power, and a nighttime visible energy fraction. Increased understanding of fire regimes is currently compelling, because fire in human-dominated landscapes is poorly defined, and extreme wildland fire is increasing, largely under the control of weather and climate, which then feeds back to these weather and climate systems.- Publication:
