The aim of this project is to develop methods for deriving Land Surface Temperature (LST) and Surface Spectral Emissivity (SSE) retrieval approaches with the Specim Aisa Owl data, evaluate algorithmic performances using ground measurements and to demonstrate the potential for demonstrate validation of satellite-based retrieval of LST and SSE. This project used NERC-ARF Remote Sensing instruments collected on board the British Antarctic Survey (BAS) Twin-Otter aircraft.
