v1.4.2 (2024 Tree Cover Loss Update)

1. 2024 Annual Tree Cover Loss Update: This version of the model is updated to run through 2024 (2001-2024). Updates involved in this are: new tree cover loss (TCL) data, new tree cover loss from fires (TCLF) data, and an updated, 1km-resolution drivers of tree cover loss (Sims et al. 2025).
2. N₂O Emissions from Soil Nitrogen Mineralization: In addition to estimating CO₂ emissions from the loss of soil organic carbon, the model now also estimates nitrous oxide (N₂O) emissions from the mineralization of soil nitrogen when soil organic carbon is lost. When a forest undergoes a land use change, nitrogen that was previously stored in the soil can be released as N₂O. For these estimates, the model follows IPCC guidelines where the driver of tree cover loss is permanent agriculture, shifting cultivation, hard commodity production or settlement and infrastructure.
3. Updated Pre-Processing for 1km Drivers: The 1km drivers of tree cover loss map is a global raster with 8 bands: the first band is the classification and the remaining bands are class probabilities. We only need to use the classification in the forest flux model so we have added logic to the warp_to_hansen function to use only band 1 for the 1km drivers of tree cover loss pre-processing step.
