Implication

Modeling analysis demonstrates reduced cloud extinction coefficient estimation errors in thin clouds, suggesting improved accuracy for optical depth measurements.

Key Points

To evaluate the feasibility and accuracy of estimating cloud extinction coefficients from single- and multiple-wavelength lidar backscatter measurements.
Modeled backscatter and extinction relationships for spherical cloud droplet polydispersions with a 5-microm width across particle radii between 1 and 100 microm.
Evaluated coefficient ratio stability and retrieval accuracy across single-wavelength (visible and near-visible) and multiwavelength lidar systems.
Single-wavelength visible and near-visible lidar systems retrieved extinction coefficients for thin clouds with an error of ~15%.
Incorporating multiple lidar wavelengths reduced the extinction coefficient estimation error to ~9%.
