Imaging/sampling atmospheric events over different spatial and time scales

Combinations of imaging equipment analyzed relatively dim, moving subjects from 360-degree auroras to 1-arc-sec resolution of the International Space Station in orbit. Extremely wide fields, of meteors, used a Nikon fisheye adapter, Intervac 3rd-generation image intensifier, and Sony digital video camera. For the 2007 Aurigid meteors, the author and nearby NASA-Ames obtained local data with a Sony HD video camcorder simultaneously with Nikon D200 dSLR, each with enough sensitivity for bright meteors and background stars, in ~40-degree overlapping fields, suitable even in light pollution. That dSLR allows WAAS GPS to record all four dimensions precisely, directly into each image file, with the image. No detectable deceleration of a bright Aurigid meteor occurred throughout the 0.4 seconds of its visibility, imaged at 30 frames per second. Diverse methods will unveil atmospheric strata.
