They were generated from the Full Carbon Accounting Model (FullCAM), which was used to estimate per-hectare land clearing emissions across the entire NT, at a spatial resolution of 250 m x 250 m. Average expected outcome was calculated over a 40-year period (12-1977 to 12-2017) to include variability associated with historical fire. Total emissions resulting from land clearing (in units CO2-e) are calculated as the sum of the four ecosystem components (above- and below-ground living biomass, above-ground debris, and above-ground standing dead). - AboveGroundLivingBiomass_tCO2e_ha.tif image depicts predicted above-ground living biomass and presented in units of tonnes of carbon dioxide-equivalent per hectare (tCO2-e ha-1) - BelowGroundBiomass_tCO2e_ha.tif image depicts below-ground biomass, presented in units of tonnes of carbon dioxide-equivalent per hectare (tCO2-e ha-1) - AboveGroundForestDebris_tCO2e_ha.tif image depicts above-ground forest debris, presented in units of tonnes of carbon dioxide-equivalent per hectare (tCO2-e ha-1) - AboveGroundStandingDead_tCO2e_ha.tif image depicts above-ground standing dead trees, presented in units of tonnes of carbon dioxide-equivalent per hectare (tCO2-e ha-1) - TotalEmissions_tCO2e_ha.tif image depicts total biomass, presented in units of tonnes of carbon dioxide-equivalent per hectare (tCO2-e ha-1)Department use onlyEnglish-26-101291381977-12-012017-12-01datasetnot knownComplete0not knownna0not knownGeoTIFF grid has a spatial resolution of 250 m x 250 m0not knownna0To generate the mapped products, the FullCAM model was used to estimate per-hectare land clearing emissions across the entire NT, at a spatial resolution of 250 m x 250 m. Predicted emissions in response to land clearing events were calculated as the sum of the four carbon pools assumed to return to the atmosphere as a result of clearing: aboveground biomass, belowground biomass, aboveground debris, aboveground standing dead. To provide a generalised emissions estimate, the average expected outcome was calculated over a 40-year period to include variability associated with historical fire. The assumption was made that tree growth was experiencing average environmental conditions. The model created by CSIRO referred to land clearing datasets in the NT for the years 2003-2020 - Pastoral land, >300 ha clearing area; and Unzoned land, >50 ha clearing area.
