28 September 2016 This directory contains the data collected by the Halo Streamline Doppler lidar that was provided by the Department of Energy Atmospheric Radiation Measurement (ARM) program for PECAN. This lidar was included in mobile PISA #3 (the University of Wisconsin - Madison's SPARC facility) during PECAN, and thus collected data in different locations nearly every day. The PI of this facility is Dr. Tim Wagner. The contact for the ARM contribution to PECAN is Dr. Dave Turner (NOAA/NSSL). This directory contains the data collected by the lidar when it was vertically pointing. All data are directly from the lidar with the exception of the "cloud base height" field, which was derived using a simple threshold technique (and this should be improved). These data were re-processed in June 2016 after a bug was found in the original dataset (that was processed in Feb 2016). The dataset was uploaded on 28 September 2016.
