“…Coupling of polarorbiting satellites such as MODIS (500 m, 4 times in a day) and geostationary-orbiting satellites (e.g. ~4km, every 5-15 minutes for GOES) might be useful to increase the number of observations over the target area (Li et al 2019). Inverse model calculation with a ground-based observation network would be of importance to improve the spatio-temporal variation in a priori emissions (Lucas et al 2017;Pisso et al 2019b;Guo et al 2018).…”

“…local time (Li et al, 2018). Due to this limited temporal coverage of fire observations in a given location, some fire emissions inventories or models supplement the diurnal cycle of emissions using FRP observations from geostationary satellites (Andela et al, 2015; Li et al, 2019; Mota & Wooster, 2018; Mu et al, 2011; Zhang et al, 2012) or assume a Gaussian distribution of daily FRP (Kaiser et al, 2009).…”

Wildfire smoke influences on air quality and atmospheric chemistry have been underscored by the increasing fire prevalence in recent years, and yet, the connection between fire, smoke emissions, and the subsequent transformation of this smoke in the atmosphere remains poorly constrained. Toward improving these linkages, we present a new method for coupling high time-resolution satellite observations of fire radiative power with in situ observations of smoke aerosols and trace gases. We apply this technique to 13 fire plumes comprehensively characterized during the recent FIREX-AQ mission and show that changes in fire radiative power directly translate into changes in conserved smoke tracers (CO 2 , CO, and black carbon aerosol) observed in the downwind smoke plume. The correlation is particularly strong for CO 2 (mean r > 0.9). This method is important for untangling the competing effects of changing fire behavior versus the influence of dilution and atmospheric processing on the downwind evolution of measured smoke properties.

“…In recent years different authors have evaluated C emissions from fires and its uptakes (Exbrayat et al, 2018;Li et al, 2019;van der Werf et al, 2010;Yin et al, 2020), characterizing fire regimes (Archibald et al, 2013;Finney, 2002;Fréjaville & Curt, 2017) and planning suppression of fires (Brotons et al, 2013;Gonzalez-Olabarria et al, 2019;Trejo, 2008). Globally, it has been estimated that fires in native vegetation emit 2.2 Pg C year −1 with a substantial interannual variability (van der Werf et al, 2017).…”

Biomass burning, including fires, has been identified as the largest source of primary fine carbonaceous particles in the troposphere and one of the major drivers of global carbon (C) cycle, cloud properties, and climate. Most of the global C emissions happen in the Pantropic region. Modeling estimates suggest an increase in Mexican fire frequencies, intensity, and C emission to the atmosphere. However, no study has combined field and satellite data to estimate C emissions by fires for any tropical country. Here, we present an approach to estimate the spatiotemporal variability of fires and its total C emissions in Mexico with the associated climate that combines national fire inventories with remote sensing. We provide evidence that tropical ecosystems, particularly tropical forests at Yucatan Peninsula, Pacific Coast, and Gulf of Mexico, provide the largest C emissions with high fire densities. We found evidence to contrast the relationships of the interannual and intra-annual variability of C emissions with immediate and lagged climate effects such as El Niño and La Niña events. Data also indicate that C emissions from fires are up to 11 times higher than those from deforestation and account 19% of the total National CO 2 emissions and 5% of the total Pantropical C emissions. Because fires are related to climate change, we encourage future studies to focus on climate fire feedbacks for implementing adequate climate mitigation strategies.
