High spectral resolution lidars for AMF2 and the North Slope

Description

The University of Wisconsin has constructed a pair of new High Spectral Resolution Lidars: one for the second ARM Mobile Facility (AMF2) and the other for the North Slope site at Barrow, Alaska. The first of these was installed on January 21, 2011, in AMF2 during the STORMVEX deployment at Steamboat Springs, Colorado. This poster will describe the new instruments and their performance. The basic design follows that of the system we have operated at Eureka, Nunavut, for the past five years. The optical design is nearly identical to the airborne system we designed for use on the National Center for Atmospheric Gulfstream V aircraft, except that they have been repackaged for ground-based deployment. The mechanical structure has been redesigned to minimize thermally induced shifts in optical alignment, and the telescope has been packaged inside the instrument to protect the optics from contamination.
