New Opportunities for Combined Raman and High Spectral Resolution Lidar Retrievals

Description

The 2015 Combined HSRL and Raman lidar Measurement Study (CHARMS) demonstrated the potential for aerosol microphysical properties to be retrieved from simultaneous measurements from two ground-based lidars, the U.Wisconsin-High Spectral Resolution Lidar (HSRL) and the SGP Raman lidar [Ferarre, et al.]. The U.W.-HSRL transmits laser pulses at both 532 and 1064 nm, and the SGP Raman lidar transmits pulses at 355 nm. Merging data from these instruments afforded the opportunity to retrieve effective radius, number, surface area, volume concentrations, and fine-mode fraction under certain conditions. Upcoming redeployments of an upgraded version of the North Slope HSRL (NSHSRL) and the Oliktok Raman lidar will provide new opportunities for multi-wavelength lidar investigations and data products. Upon completion of the upgrade, the NSHSRL will transmit and receive both 532 nm and 1064 nm signals and will be redeployed for an extended period of time at the Southern Great Plains (SGP) site near the SGP Raman lidar, enabling collection of a second CHARMS dataset at the SGP. Planning is underway for the AMF3 Raman lidar currently in Oliktok to be redeployed at the North Slope site in Utqiaġvik, AK. When redeployments of the Oliktok Raman lidar and NSHSRL are complete, analyses of merged data from the Raman-lidar, HSRL, and other instruments at the NSA site will be possible, enabling collection of a CHARMS dataset at the NSA site. We describe here planned upgrades by the University of Wisconsin to the capabilities of the NSHSRL and initial plans for deployment of the NSHSRL at the SGP site in 2020 and future deployment of the Oliktok Raman Lidar and NSHSRL in Utqiaġvik.
