Synergistic exploitation of the methane product from Sentinel-SP for applications in the Arctic (STEPS)
The main goal of this feasibility study was to evaluate the potential of adding value to the Sentinel 5P TROPOMI methane product over Norway and the Arctic through the synergistic use of relevant observations from other Sentinel satellites and machine learning. We assessed the data availability of E...
