- The MALIBU project (Multi AngLe Imaging Bidirectional Reflectance Distribution Function small UAS) (PI: Zhuosen Wang (619/UMD); Co-Is: M. Román (619), N. Pahlevan (619/SSAI), J. McCorkel (618), G. Bland, (610W)) completed its second series of validation flights at the NOAA Table Mountain Facility (Boulder, Colorado) on Nov 30. NOAA Table Mountain is one of seven stations of the Surface Radiation (SURFRAD) network; a component of the World Climate Research Programs (WCRP) Baseline Surface Radiation Network (BSRN). Tower-based surface radiation datasets, combined with MALIBU overflights are being used to validate a number of EOS and Suomi-NPP standard products, including Surface Reflectance, Albedo, and Reflectance Anisotropy. Validations studies have shown that airborne observations are critical to overcome errors of scale and spatial heterogeneity in the in-situ measurements. The multi-angular high spatial resolution (<1m) MALIBU observations cover a much larger area than ground measurements and provide high quality datasets to validate multi-spatial resolution satellite products; such as those derived from MODIS, VIIRS, and Landsat OLI. MALIBU is a pathfinder activity whose purpose is to develop a multi-angle reflectance measurement technique for global land product calibration and validation using small Unmanned Aircraft Systems (sUAS). This work is funded under the NASA/GSFC IRAD and SBIR programs and the Joint Polar Satellite System (JPSS).

The MALIBU project (Multi AngLe Imaging Bidirectional Reflectance Distribution Function small UAS) (PI: M. Román, 619; Instrument-PI: N. Pahlevan, 619/SSAI; Co-Is: Z. Wang, 619/UMD, J. McCorkel, 618, G. Bland, 610W) completed the first series of test flights at Pawnee National Grasslands, Colorado (June 28-30, 2016; link to video brief: https://youtu.be/Vd8c-4rXQOo). MALIBU is a pathfinder series of missions to develop a multi-angle reflectance measurement technique for global land product calibration and validation using small Unmanned Aircraft Systems (sUAS). The instrument package includes two multispectral imagers oriented at two different viewing angles to capture vegetation structure and spectral characteristics. The series of test flights were collocated with NIST-traceable measurements of calibration tarps, and supported by a ground surveying crew for post-process geolocation. The last test flight, Flight #003 on 30 June 2016, was successfully completed during a Landsat-8 overpass. These measurements will assist in evaluating OLI-derived surface reflectance and biogeophysical products at unprecedented scales (i.e., high spatial (<20 cm) and multi-angular (< 0.5 degree) resolutions). The MALIBU team would like to thank Christy Hansen (610), Barbara Justis (840), and Gerrit Everson (830) for their assistance during the MALIBU Airworthiness and Flight Safety Review Board (AFSRB), and for their guidance in processing the FAA Certificates of Authorization (COA-G) for the Pawnee field site.
