In the text files with emissions for each fire, the aerosols (BC, OC, PM2.5, PM10), as well as the gas-phase lumped species 'NOXasNO' and NMOC, are in units of kg/day, and the gas-phase species are in moles/day. In these files 'AREA' is the area burned in m^2; 'BMASS' is the biomass burned per area burned in kg/m^2. 'GENVEG' specifies the vegetation type assumed for the fire: 1 = grasslands and savanna; 2 = woody savanna/shrublands; 3 = tropical forest; 4 = temperate forest; 5 = boreal forest; 6 = temperate evergreen forest; 9 = croplands; 0 = no vegetation.
In the 0.1x0.1 degree gridded files, all compounds are converted to molecules/cm^2/sec, where aerosols have been converted from kg to molecules using molecular weight of 12 g/mole.
The text files also contain POLYID and FIREID. Each fire point identified by satellites is assigned a POLYID. Each POLYID is assigned to a FIREID. If multiple fire points are located together as part of a big fire, they are assigned to the same FIREID.
FRP (in MW, megawatts) is also included in the text (each_fire) files. FRP is not used in the calculation of FINN emissions, but has been averaged to each 1-km fire in FINN emissions for potential use by users.
Note on FINNv2.5.1_modvrs_nrt_base_FRP_*.txt files: When reading these files, please use a space as the column delimiter as a comma is missing in the middle of each line. This is fixed starting with Jan 2025 files.
