چکیده

Near-real time estimates of biomass burning emissions are important for air quality monitoring and forecasting. We present here the preliminary analysis of global biomass burning emission product (GBBEP) produced from geostationary-satellite-derived fire radiative power (FRP) in near-real time. Specifically, the FRP is retrieved at an interval of 15 to 30 minutes using WF_ABBA_V65 (Wildfire Automated Biomass Burning Algorithm) from multiple geostationary satellites. The missing FRP detections are simulated by combining the available instantaneous FRP observations within a day and the representative ecosystem-dependent climatologic diurnal pattern of half-hourly FRPs. Finally, the diurnal variation in FRP is applied to quantify global emissions of PM2.5 (particulate mass for particles with diameter < 2.5 μm) and trace gases with a one-day latency. The algorithm is tested by analyzing global patterns in hourly biomass burning emissions for 2010.

Daily and 3‐hourly variability in global fire emissions and consequences for atmospheric model predictions of carbon monoxide

[1] Attribution of the causes of atmospheric trace gas and aerosol variability often requires the use of high resolution time series of anthropogenic and natural emissions inventories. Here we developed an approach for representing synoptic‐ and diurnal‐scale temporal variability in fire emissions for the Global Fire Emissions Database version 3 (GFED3). We disaggregated monthly GFED3 emissions...

Global Near-Real-Time Estimates of Biomass Burning Emissions using Satellite Active Fire Detections

We present a new technique for generating daily global estimates of biomass burning emissions suitable for use in models forecasting atmospheric chemical composition and air quality. We combine ecosystem-dependent carbon fuel databases, fire weather severity estimates, and near-real-time satellite fire detections from the MODIS instruments to estimate the amount of carbon released from active f...

Satellites may underestimate rice residue and associated burning emissions in Vietnam

In this study, we estimate rice residue, associated burning emissions, and compare results with existing emissions inventories employing a bottom-up approach. We first estimated field-level post-harvest rice residues, including separate fuel-loading factors for rice straw and rice stubble. Results suggested fuel-loading factors of 0.27 kgm (±0.033), 0.61 kgm (±0.076), and 0.88 kgm (±0.083) for ...
