Cloud parameters from infrared lidar used singly and in combinationwith radar and infrared radiometer

摘要

A CO₂ lidar operating at wavelength of aboutnλ=10.6 μm differs in some respects from most other lidars,nwhich operate at wavelengths an order of magnitude smaller. Onenimportant difference is that ice and water particles absorb strongly atnCO₂ lidar wavelengths, whereas scattering dominates at thenshorter wavelengths. The authors are developing cloud-sensing techniquesnthat rely on the unique characteristics of a coherent CO₂nDoppler lidar
