ARM Micropulse Lidar: Configuration Upgrades and New Data Products

Flynn, C.J., Mendoza, A., and Christy, J., Pacific Northwest National Laboratory
Fourteenth Atmospheric Radiation Measurement (ARM) Science Team Meeting

The ARM Program has operated Micropulse Lidar (MPL) systems for more than one decade. However, the MPL instrument configuration and data product development has been essentially static for the last five years. Meanwhile, as ARM's deployed MPL systems continue to age they exhibit decreasing performance and an increasing frequency of repair. To stem this tide, ARM has begun to implement several MPL configuration changes to improve routine operation. In addition, some of these changes yield significant new capablity. MPL systems with improved optics have been deployed at SGP and TWP Manus. A prototype MPL with polarization sensitivity has been deployed to NSA Barrow. A schedule for deployments at other sites is provided. New routine data products are in development to capitalize on the new measurement capabilities. Aerosol backscatter and extinction profiles will be produced as routine data products. Polarization products will be routinely available for those sites with polarization-sensitive MPL systems. Preliminary results demonstrating these products are presented.
