Synchronized Starphotometry and Lidar measurements in the High Arctic

The sunphotometry-lidar synergy has proven to be effective for the characterization of aerosol events in the High Arctic. Sunphotometry measurements, however, are limited to the day-time periods. Starphotometry, based on the extinction of bright-star radiation, can mitigate the lack of aerosol optic...

Description
Summary:The sunphotometry-lidar synergy has proven to be effective for the characterization of aerosol events in the High Arctic. Sunphotometry measurements, however, are limited to the day-time periods. Starphotometry, based on the extinction of bright-star radiation, can mitigate the lack of aerosol optical depth (AOD) measurements during the Polar Night. In this work we present several examples of the coincident starphotometry-lidar measurements at Eureka, Canada (79°59'N, 85°56'W) obtained in Feb-Mar 2011. We show a correlation between fine (sub-micron) and coarse (super-micron) mode AOD dynamics from starphotometry and the backscatter profiles and depolarization ratio values from the lidar data.
