From: Improved modelling of biogenic emissions in human-disturbed forest edges and urban areas
Each panel illustrates a set step in the calculation of BVOC emissions. A Calculate the standard emission factor grid map (EFMAP) in MEGAN2.1 based on plant functional types (PFTs) and emission factor (EF); B Derivation of leaf area index (γLAI) and environmental activity factor (γA) in MEGAN2.1; C Calculation of temperature (γT) and light (γP) activity factors using meteorological data in MEGAN 2.1; D Dynamic standard emission factor grid map construction in GEE-MEGAN, incorporating land use/cover change (LUCC) and wildfire data. E Updated calculation of γLAI and γA in GEE-MEGAN using high-resolution LAI data from Landsat.
