Polarization effects on oceanographic lidar

Polarization in Lidar

Transient radiative transfer equation applied to oceanographic lidar.

We estimate the optical signal for an oceanographic lidar from the one-dimensional transient (time-dependent) radiative transfer equation using the discrete ordinates method. An oceanographic lidar directs a pulsed blue or green laser into the ocean and measures the time-dependent backscattered light. A large number of parameters affect the performance of such a system. Here the optical signal ...

Polarization Diversity Lidar (pdl) Development

As reviewed at the start of the ARM Program (Sassen 1991), polarization lidar techniques have unique cloudsensing capabilities, particularly with regard to the unambiguous discrimination of cloud phase and acx:urate determination of cloud boundaries. Various polarization techniques had not been systematically evaluated in the field, but such evaluations could now be facilitated by modern lidard...

Polarization lidar for shallow water depth measurement.

A bathymetric, polarization lidar system transmitting at 532 nm and using a single photomultiplier tube is employed for applications of shallow water depth measurement. The technique exploits polarization attributes of the probed water body to isolate surface and floor returns, enabling constant fraction detection schemes to determine depth. The minimum resolvable water depth is no longer dicta...

Fine and coarse dust separation with polarization lidar

The polarization-lidar photometer networking (POLIPHON) method for separating dust and non-dust aerosol backscatter and extinction, volume, and mass concentration is extended to allow for a height-resolved separation of fine-mode and coarse-mode dust properties in addition. The method is applied to a period with complex aerosol layering of fine-mode background dust from Turkey and Arabian deser...
