The project prepares Sentinel-2 data (2017–present) for use in the GHG inventory and examines whether the methods can be transferred to Landsat data to extend the time series back to 1990. It investigates the distinguishability of 19 annual crops and six grassland types. The goal is to create a consistent, spatially explicit time series (1990–present) in line with IPCC guidelines, serving as input for RothC modeling in the national greenhouse gas inventory.
