The maps were generated by using a machine learning-based regression and a set of spatial data layers to upscale ALT from narrow swaths of ALT that were retrieved from airborne high-resolution P-band Polarimetric Synthetic Aperture Radar (PolSAR) imagery. The data are provided in cloud-optimized GeoTIFF format.}, publisher={ORNL Distributed Active Archive Center}, author={Whitcomb, J. and Chen, R.H. and Clewley, D. and Kimball, J. and Pastick, N.J. and Yi, Y. and Moghaddam, M.}, year={2024}, language={en}, }
