The Use of Lidar Technology for Measuring Mixing Heights under the Photochemical Assessment Monitoring Stations (PAMS) Program

摘要

The results show the CL-51 is capable of capturing hourlymixing height values. Examples were shown, Figure 4B, ofhow aerosol residual layers influence MH estimation. However,when appropriate screening criteria were applied to theCL-51 data, the correlations between the CL-51 MH andABLH estimates from the radiosondes significantly improvedfor the Golden site, and slightly decreased for the BAO site.On average, the radiosonde ABLH was higher than the CL-51 MH at the BAO (Erie, CO) (390 m (15%)) site, and lowerat the Golden (CO) site (-240 m (9%)). A limited numberof radiosondes was conducted during nighttime hours,and therefore nighttime MH were not evaluated. Despitedifferences in the two methodologies, the agreement remainsencouraging.
