NSF/NCAR GV HIAPER Raw 2D-S Imagery. Version 1.1

A 2D-S instrument contains two 2D probes which image particles as they pass through beams that are oriented orthogonally to each other and the airflow. If particles also lie in the intersection of the sensitive areas of the two beams, they are seen by both 2D probes. This dataset contains 2D-S imagery collected aboard the NSF/NCAR GV during the SOCRATES project using the SPEC 2D-S (Stereo) probe. The original files have been processed so that they are compatible with xpms2d software. All files reflect UTC time.
