This article presents results from the joint DISCOVER-AQ/FRAPPÉ field campaigns conducted over Denver and the Front Range area, where Lidar technology was used to measure mixing heights and compared to atmospheric boundary layer heights determined by radiosondes.
The operational use of ceilometers across the United States has been limited to detection of cloud-base heights across the Automatic Surface Observing Systems (ASOS) primarily operated by the National Weather Service and the Federal Aviation Administration. Continued improvements in the underlying technology over the past decade has resulted in the use of ceilometers to identify aerosol layers throughout the troposphere including the atmospheric mixing heights. With the forthcoming requirement to measure hourly mixing heights under the U.S EPA Photochemical Assessment Monitoring Stations (PAMS) program, ceilometers may provide a cost effective technological solution. During the joint DISCOVER AQ/FRAPPÉ Field Campaigns conducted over Denver and the Front Range area two CL-51 ceilometers were used to measure mixing heights and compared to atmospheric boundary layer heights determined by radiosondes.
