During June 2019 the NASA JPL Hyperspectral Thermal Emission Spectrometer (HyTES) instrument, one of the most sophisticated thermal instruments flown for the first time outside the US alongside NCEO’s Specim Fenix hyperspectral instrument as part of the NET-Sense project. The aim was to collect airborne data over a number of sites which could be used to inform the proposed European Space Agency High Spatio-Temporal Resolution Land Surface Temperature Monitoring (LSTM). In addition to airborne data an extensive field campaign was carried out using equipment on loan from the NERC Field Spectroscopy Facility.
After data collection, the Specim Fenix data were sent to NEODAAS for processing, continuing the capability previously operated through the NERC Airborne Research Facility Data Analysis Node where they were calibrated and georeferenced. Working with the NET-Sense team the data will be atmospherically corrected to produce surface reflectance measurements, utilising measurements collected from FSF sun photometers and spectrometers.
