T-REX: DLR Doppler Lidar Data

Summary

The Terrain-Induced Rotor Experiment (T-REX) took place in March/April 2006 in the Owens Valley, Sierra Nevada, California. The DLR Institut für Physik der Atmosphäre operated a coherent 2µm Doppler lidar from LMCT to investigate the dynamics of mountain waves and rotors. The measurements were coordinated with a similar Doppler lidar operated by Arizona State University. The systems operated simultaneously for about 6 weeks. The first deployment of two Doppler lidars for mesoscale meteorological research made it possible to retrieve horizontal and vertical wind components in vertical cross sections perpendicular to the valley axis. The lidars performed nearly continuous measurements throughout 6 weeks, which included several interesting events outside of Intensive Observation Periods (IOPs).

The data are in tar files by day. Matlab scripts to analyze the data are included, as well as a binary program to convert the *.PRD data files to ASCII files.
