A High Spectral Resolution Lidar for the Arctic - A Progress Report

Eloranta, E.W., Razenkov, I., Kuehn, R., Holz, R., Hedrick, J., and Garcia, J., University of Wisconsin-Madison
Twelfth Atmospheric Radiation Measurement (ARM) Science Team Meeting

The University of Wisconsin is constructing a High Spectral Resolution Lidar for deployment in the Arctic. It is designed to operate as an internet appliance and require minimal attention from an onsite attendent. It will provide continuous well calibrated profiles of optical depth, cloud phase and backscatter cross sections. Deployment at the Point Barrow ARM facility is proposed. This poster will describe progess to date. Initial testing has demonstrated that the shared transmitter/reciever telescope design functions properly. While this approach eliminates alignment problems which make untended operation difficult, it is subject to problems with detector overload by light scattered out of the tranmitted pulse. The optical system has been constructed, the temperature controlled housing is nearly complete, and the last elements of the data system are scheduled for delivery before this meeting. The poster will describe the system and present test data.
