Profiles of aerosol backscattering and extinction, water vapor mixing ratio, and relative humidity have been routinely
measured around-the-clock during the last several years by a turnkey, automated Raman lidar system located at the Dept. of
Energy (DOE) Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) Climate Research Facility (CRF). These
Raman lidar aerosol extinction profiles are used to evaluate aerosol extinction profiles and aerosol optical thickness (AOT)
simulated by the Georgia Tech/Goddard Global Ozone Chemistry Aerosol Radiation and Transport (GOCART) and Interaction with
Chemistry and Aerosols (INCA) global aerosol models' simulations for the year 2000. The GOCART and INCA model average
aerosol extinction profiles show good agreement with the Raman lidar profiles for altitudes above about 2 km; below 2 km the
average model profiles are significantly (30-50%) lower than the Raman lidar profiles. The vertical variability in average
aerosol extinction profiles simulated by these models is less than the variability in the corresponding Raman lidar profiles.
Planetary Boundary Layer (PBL) heights derived from the Raman lidar water vapor and aerosol profiles acquired between
January 2000 and December 2002 were used to evaluate the amount of aerosol optical thickness (AOT) within and above the PBL.
A significant fraction ($>$25%) of the AOT was typically located above the PBL. Raman lidar measurements of the aerosol
extinction/backscatter ratio acquired during the May 2003 Aerosol Intensive Operations Period (IOP) are used in conjunction
with airborne remote and in situ aerosol measurements to estimate aerosol refractive index and single scatter albedo.
Comparisons of these and other results derived from the Raman lidar measurements acquired during this IOP with measurements
from other remote and in situ sensors are presented.
