NASA's Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) released the first dataset from the Airborne Validation Unified Experiment: Land to Ocean (AVUELO) project.
This dataset contains Level 2A (L2A) orthocorrected surface reflectance and uncertainty estimates from the Airborne Visible / Infrared Imaging Spectrometer-3 (AVIRIS-3). This L2A data product was generated with a provisional calibration algorithm.
AVUELO aims to advance the validation and calibration of spaceborne imaging spectroscopy (hyperspectral) data for tropical ecosystems by combining airborne imaging spectroscopy for terrestrial and marine sites in Panama and Costa Rica with contemporaneous field measurements and data collected in February 2025.
