Overview

abstract

  • Abstract. A new open biomass burning inventory is presented that; relies on the fire radiative power data from the Visible Infrared Imaging; Radiometer Suite (VIIRS) on board the Suomi NPP satellite. This VIIRS-based; Fire Emission Inventory (VFEI) provides emission data from early 2012 to; 2019 for more than 40 species of gases and aerosols at spatial resolutions; of around 500 m. We found that VFEI produces similar results when compared; to other major inventories in many regions of the world. Additionally, we; conducted regional simulations using VFEI with the Weather Research and; Forecasting (WRF) model with chemistry (WRF-Chem) for Southern Africa; (September 2016) and North America (July–August 2019). We compared aerosol; optical depth (AOD) from the model against two observational datasets: the; MODIS Multi-Angle Implementation of Atmospheric Correction (MAIAC) product; and AErosol RObotic NETwork (AERONET) stations. Results showed good; agreement between both simulations and the datasets, with mean AOD biases of; around +0.03 for Southern Africa and −0.01 for North America. Both; simulations were not only able to reproduce the AOD magnitudes accurately,; but also the inter-diurnal variations of smoke concentration. In addition,; we made use of the airborne data from the ObseRvations of Aerosols above; CLouds and their intEractionS (ORACLES; Southern Africa) and the Fire; Influence on Regional to Global Environments Experiment and Air Quality; (FIREX-AQ; North America) campaigns to evaluate the simulations. In Southern; Africa, results showed correlations higher than 0.77 when comparing carbon; monoxide and black carbon. In North America, correlations were lower and; biases higher. However, this is because the model was not able to reproduce; the timing, shape, and location of individual plumes over complex terrain; (Rocky Mountains) during the FIREX-AQ campaign period.;
