Simultaneous observations of lower tropospheric continental aerosols with a ground-based, an airborne, and the spaceborne CALIOP lidar system

Spaceborne observations of the lidar ratio of marine aerosols

Retrievals of aerosol optical depth (AOD) from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) satellite sensor require the assumption of the extinction-to-backscatter ratio, also known as the lidar ratio. This paper evaluates a new method to calculate the lidar ratio of marine aerosols using two independent sources: the AOD from the Synergized Optical Depth of Aerosols (SODA) pro...

Airborne and Spaceborne Lidar

The evolution of lidar, from those early ground-based measurements to our first long-duration spaceborne experiments, is schematically represented in Fig. 13.1. It depicts the first lidars in the 1960s as ground-based, followed by systems first flown in 1969 on small aircraft, and followed in the late 1970s by lidars flown on large aircraft capable of long-range measurements. Starting in 1979, ...

A comparison of ground-based Doppler lidar and airborne in situ wind observations above complex terrain

Airborne wind observations collected by the National Oceanic and Atmospheric Administration’s (NOAA) WP-3D aircraft are compared with the winds retrieved by the NOAA/Environmental Technology Laboratory’s ground-based scanning Doppler lidar within the Wipp Valley during the Special Observing Period of the Mesoscale Alpine Programme. Comparisons are performed along individual  ight tracks and ov...
