Improved Simulations of Biomass Burning Aerosol Optical Properties and Lifetimes during the ORACLES-I Campaign: Results from the NASA GEOS Model

Published by NASA | National Aeronautics and Space Administration | Metadata Last Checked: August 04, 2025 | Last Modified: 2025-04-23
This dataset contains model results and satellite-based research retrievals associated with the manuscript submitted in Atmospheric Chemistry and Physics Journal, titled, " Improved Simulations of Biomass Burning Aerosol Optical Properties and Lifetimes in the NASA GEOS Model during the ORACLES-I Campaign". There were multiple NASA GEOS global model simulations performed for this study. Following are the name of the simulation and their description corresponding to the file names within this dataset: 1. Baseline: Default version of the GEOS model 2. Smoke Age: Default version of the GEOS model run with biomass burning OA tagged by day of the week it was emitted. 3. Smoke Composition: Default version of the GEOS model run with biomass burning OA tagged by type of vegetation burned. 4. OA-loss: Hydrophilic OA from biomass burning is assigned a 6-day e-folding loss time; OA from biomass burning sources is enhanced 60%, BC from biomass burning sources is enhanced 15%. 5. OA-loss+updated optics: As in OA-loss but with updated aerosol optical properties.
