The radar instrument is a fully polarimetric P-band (ultra-high frequency) SAR operating in the 420-440 MHz band. The flight campaigns took place periodically in May-August 2017 onboard a NASA Gulfstream-III aircraft. Each set of products was produced from a data take (i.e., acquisition) of the UAVSAR P-band SAR radar instrument, where one data take is equivalent to one flight line over a site. Two to four data takes were sought for each site, although for some sites as few as one or as many as six are provided. There were a total of 139 data takes over the 74 sites.}, publisher={ORNL Distributed Active Archive Center}, author={Shimada, J.G. and Lou, Y. and Hensley, S. and Hawkins, B.P. and Harcke, L. and Lagoy, D.M. and Michel, T.R. and Muellerschoen, R.J. and Flores, S. and Pinto, N. and Rains, C. and Tung, W.W. and Zheng, Y.}, year={2021}, language={en}, }
