Hyperspectral Ground Calibration Data - Spectroradiometer, Australian Field Sites 

Field spectroradiometer measurements have been collected at several locations across Australia (formally known as the AusCover Supersites) to relate field based measurements to satellite data products, such as Landsat and MODIS NBAR products. Collected in collaboration with multiple government and research-based institutions. 

We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging. The Joint Remote Sensing Research Project was primarily responsible for the curation of this data set, however the following organisations contributed to the data collection: Royal Melbourne Institute of Technology, Curtin University, University of Adelaide and CSIRO.
This work was funded by the Terrestrial Ecosystem Research Network (TERN), an Australian Government National Collaborative Research Infrastructure Strategy (NCRIS) project. 

The Hyperspectral ground-based data is used for calibration and validation of at-surface reflectance of airborne hyper-spectral image data. Once the at-surface reflectance values of the hyper-spectral image data have been validated, the data can be used for up-scaling to medium spatial resolution Landsat and MODIS data for cal/val of NBAR products. 

Data is typically collected from standardised calibration targets (white, grey and black) laid out in an open area within or nearby the site. Data is collected in a zig zag pattern of points over the target at approximately 1 m intervals. Natural features (roads, soils, grass, irradiance) are also collected opportunistically.
