description:
|
1) Downloaded daily near real time VIIRS hot spot data, with lat/lon and Fire Radiative Power (FRP) data, from the following sources:
- ftp://ftp.star.nesdis.noaa.gov/pub/smcd/emb/fire/VIIRS/VIIRS_375m_SNPP
- ftp://ftp.star.nesdis.noaa.gov/pub/smcd/emb/fire/VIIRS/VIIRS_375m_NOAA20
2) Data is filtered to only include closest to nadir data points from NOAA20 or SNPP
3) A gridded geotiff of hot spot detections is created, and overlaid with 500m MODIS landcover tiles, so that FRP per landcover type can be summed, for each GFED fire type: Deforested, Temperate Forest, Boreal Forest, Savannah, Agriculture, Peat.
4) Emissions estimates are calculated by multiplying various FRPs per fire type with teh GFED4_Emissions_Factors table, creating the 6 band output of emissions estimates: 1) Dry matter, 2) carbon, 3) carbon dioxide, 4) carbon monoxide, 5) methane, 6) particulate matter. |
